首先我们要明白一下几点，
1.代码写出来除了让他跑起来还有个非常非常重要的作用是维护，因为没有一成不变的代码，需求变化代码就不可避免的要变化。
2.你不是一个人在写代码，你身后有一个团队，这个团队中任何一个人都有可能会改你的代码，你如果写的不规范，后面的人会跟着写。举一个例子，最初的代码可能是这样的，
if (orderinfo.o_ordersentity.directflightchannel.trim().toupper() == "cz-sp")
{
ordercostandweightentity e = new ordercostandweightentity();
e.flightagency = insurancecommon.getstrategyflightagencynew(orderinfo.o_ordersentity.directflightchannel);
e = regetflight.getdirectflighthighweightentity(orderinfo.o_flightentity, "", e.flightagency);
e.sendticketcity = int.parse(configurationmanager.appsettings["sendticketcityofdirectflights_hu"].tostring());
regetflightinitdata.highcostandweightentity = e;
regetflightinitdata.tickettype = "0001";
//如果是海航,则不需要政策倒查验证
regetflightinitdata.researchnoflight = false;
}
else
{
ordercostandweightentity e = new ordercostandweightentity();
e.sendticketcity = int.parse(configurationmanager.appsettings["sendticketcityofdirectflights_hu"].tostring());
e.flightagency = insurancecommon.getstrategyflightagencynew(orderinfo.o_ordersentity.directflightchannel);
e.costrate1 = 1.0m;
regetflightinitdata.highcostandweightentity = e;
//如果是海航,则不需要政策倒查验证
regetflightinitdata.researchnoflight = false;
}
但是过一时间又来个需求，对于“mu-ws”也需要走上面的逻辑，你会怎么写，如果你只是完成任务可能会像下面这样写
if (orderinfo.o_ordersentity.directflightchannel.trim().toupper() == "cz-sp" || orderinfo.o_ordersentity.directflightchannel.trim().toupper() == "mu-ws")
{
ordercostandweightentity e = new ordercostandweightentity();
e.flightagency = insurancecommon.getstrategyflightagencynew(orderinfo.o_ordersentity.directflightchannel);
e = regetflight.getdirectflighthighweightentity(orderinfo.o_flightentity, "", e.flightagency);
e.sendticketcity = int.parse(configurationmanager.appsettings["sendticketcityofdirectflights_hu"].tostring());
regetflightinitdata.highcostandweightentity = e;
regetflightinitdata.tickettype = "0001";
//如果是海航,则不需要政策倒查验证
regetflightinitdata.researchnoflight = false;
}
else
{
ordercostandweightentity e = new ordercostandweightentity();
e.sendticketcity = int.parse(configurationmanager.appsettings["sendticketcityofdirectflights_hu"].tostring());
e.flightagency = insurancecommon.getstrategyflightagencynew(orderinfo.o_ordersentity.directflightchannel);
e.costrate1 = 1.0m;
regetflightinitdata.highcostandweightentity = e;
//如果是海航,则不需要政策倒查验证
regetflightinitdata.researchnoflight = false;
}
如果真的这么写你就是始作俑者，后面的人如果都和你一样就都会朝着葫芦画瓢，最后代码可能会是这样的
if (orderinfo.o_ordersentity.directflightchannel.trim().toupper() == "cz-sp" || orderinfo.o_ordersentity.directflightchannel.trim().toupper() == "mu-ws" || orderinfo.o_ordersentity.directflightchannel.trim().toupper() == "mu-ws" || orderinfo.o_ordersentity.directflightchannel.trim().toupper() == "mu-sp" || orderinfo.o_ordersentity.directflightchannel.trim().toupper() == "cz-ws" || orderinfo.o_ordersentity.directflightchannel.trim().toupper() == "xt-ws")
{
ordercostandweightentity e = new ordercostandweightentity();
e.flightagency = insurancecommon.getstrategyflightagencynew(orderinfo.o_ordersentity.directflightchannel);
e = regetflight.getdirectflighthighweightentity(orderinfo.o_flightentity, "", e.flightagency);
e.sendticketcity = int.parse(configurationmanager.appsettings["sendticketcityofdirectflights_hu"].tostring());
regetflightinitdata.highcostandweightentity = e;
regetflightinitdata.tickettype = "0001";
//如果是海航,则不需要政策倒查验证
regetflightinitdata.researchnoflight = false;
}
else
{
ordercostandweightentity e = new ordercostandweightentity();
e.sendticketcity = int.parse(configurationmanager.appsettings["sendticketcityofdirectflights_hu"].tostring());
e.flightagency = insurancecommon.getstrategyflightagencynew(orderinfo.o_ordersentity.directflightchannel);
e.costrate1 = 1.0m;
regetflightinitdata.highcostandweightentity = e;
//如果是海航,则不需要政策倒查验证
regetflightinitdata.researchnoflight = false;
}
看到效果了么，你需要脱一下下面的那个长条才能看到全部代码，这就是你的“因”种下后得到的果实。所以我们需要改进，常见的改进是回车换行，保证所有的代码都在你一眼能够看到的范围之内。改进后代码如下：
if (orderinfo.o_ordersentity.directflightchannel.trim().toupper() == "cz-sp" ||
orderinfo.o_ordersentity.directflightchannel.trim().toupper() == "mu-ws" ||
orderinfo.o_ordersentity.directflightchannel.trim().toupper() == "mu-ws" ||
orderinfo.o_ordersentity.directflightchannel.trim().toupper() == "mu-sp" ||
orderinfo.o_ordersentity.directflightchannel.trim().toupper() == "cz-ws" ||
orderinfo.o_ordersentity.directflightchannel.trim().toupper() == "xt-ws")
{
ordercostandweightentity e = new ordercostandweightentity();
e.flightagency = insurancecommon.getstrategyflightagencynew(orderinfo.o_ordersentity.directflightchannel);
e = regetflight.getdirectflighthighweightentity(orderinfo.o_flightentity, "", e.flightagency);
e.sendticketcity = int.parse(configurationmanager.appsettings["sendticketcityofdirectflights_hu"].tostring());
regetflightinitdata.highcostandweightentity = e;
regetflightinitdata.tickettype = "0001";
//如果是海航,则不需要政策倒查验证
regetflightinitdata.researchnoflight = false;
}
else
{
ordercostandweightentity e = new ordercostandweightentity();
e.sendticketcity = int.parse(configurationmanager.appsettings["sendticketcityofdirectflights_hu"].tostring());
e.flightagency = insurancecommon.getstrategyflightagencynew(orderinfo.o_ordersentity.directflightchannel);
e.costrate1 = 1.0m;
regetflightinitdata.highcostandweightentity = e;
//如果是海航,则不需要政策倒查验证
regetflightinitdata.researchnoflight = false;
是不是清爽一点，好看一点，如果你在第一次修改代码的时候这样写后面的人就会跟着这样写，他们可能会想，前面一个人这样写这样写应该不会有问题，虽然代码看起来有点别扭，这时候我们可以带着鉴赏的眼光看这段代码，如果再想一想还有更好的方法，为何不用switch呢？
switch (orderinfo.o_ordersentity.directflightchannel.trim().toupper())
{
case "cz-sp":
case "mu-sp":
case "xt-ws":
{
ordercostandweightentity e = new ordercostandweightentity();
e.flightagency = insurancecommon.getstrategyflightagencynew(orderinfo.o_ordersentity.directflightchannel);
e = regetflight.getdirectflighthighweightentity(orderinfo.o_flightentity, "", e.flightagency);
e.sendticketcity = int.parse(configurationmanager.appsettings["sendticketcityofdirectflights_hu"].tostring());
regetflightinitdata.highcostandweightentity = e;
regetflightinitdata.tickettype = "0001";
//如果是海航,则不需要政策倒查验证
regetflightinitdata.researchnoflight = false;
break;
}
default:
{
ordercostandweightentity e = new ordercostandweightentity();
e.sendticketcity = int.parse(configurationmanager.appsettings["sendticketcityofdirectflights_hu"].tostring());
e.flightagency = insurancecommon.getstrategyflightagencynew(orderinfo.o_ordersentity.directflightchannel);
e.costrate1 = 1.0m;
regetflightinitdata.highcostandweightentity = e;
//如果是海航,则不需要政策倒查验证
regetflightinitdata.researchnoflight = false;
break;
}
}
是不是更加简单，如果你这样写，后面的人会毫不犹豫地在后面加一个case “”：因为这个是大家再熟悉不过的语法了，丝毫不用怀疑这种写法的正确性，于是我们可以带着欣赏的眼光来看这段代码了。
3.要承认我们的心智就这么多，脑袋就这么大，我们既不能一目十行也不能出口成章，所以不要写一言看不出什么意思的代码。
以上的想法都是建立在维护别人代码的痛苦，失落，沮丧，各种不爽，各种吐槽之上，所以代码规范是需要我们时刻关注的，在这里自己总结一些规范，告诫自己不要做始作俑者。
1.一个文件中只放一个类，类名同文件名，不要在一个文件中写好几个类，这样看的清楚。
2.不要在一个文件中写多于1000行的代码，除了那些比较大的实体类。其实我还想说超过500行看起来就有点累，但是在我们的系统中超过10000行的代码比比皆是。
3.一个方法的代码不要超过100行，其实我想说超过50行的方法看起来就有点累。但是在我们的系统中超过200行代码的方法比比皆是。
4.存储过程的代码也不要超过100行,不要在存储过程中写过多的业务逻辑，那是找死，但是在我们的系统中我还真他妈的见过10000多行的存储过程，好宏伟啊！
5.避免写超过5个参数的方法，如果有请使用一个类或者结构来传。
6.一个方法只有一个return result; ，不要多次return结果，最好给返回结果赋值，最后return result;
7.不要给很简单的代码加注释，会有噪音的，会让人误解的，因为你写的大多数情况下很片面。
8.记录日志的时候不要到处都记，有条件的情况下针对客户一次操作（比如下单）只记录一条日志。
另外再这里列举自己对代码做的一些改进，不足之处欢迎大家指出。
1.参数过长使用缩进
a.
//获得保险策略信息
insurancestrategy = insurancecommon.getstrategyinsurance(appfltentity.productsource.tostring(), strategyflightagency.tostring(), "", appfltentity.price.tostring(), appfltentity.directflightchannel, appfltentity.airline.dibitcode, appfltentity.flight, appfltentity.departairport.code, appfltentity.arriveairport.code, appfltentity.subclass, appfltentity.departtime, appfltentity.departtime.date, null);
b.
//获得保险策略信息
insurancestrategy = insurancecommon.getstrategyinsurance(appfltentity.productsource.tostring(),
strategyflightagency.tostring(),
"",
appfltentity.price.tostring(),
appfltentity.directflightchannel,
appfltentity.airline.dibitcode,
appfltentity.flight,
appfltentity.departairport.code,
appfltentity.arriveairport.code,
appfltentity.subclass,
appfltentity.departtime,
appfltentity.departtime.date,
null);
2.if条件过长中使用缩进
a.
if (isdirectflight && (this.corppaytype == expensetype.own || this.accountinfo.directordersquotemode == "i"))
{
strategyflightagency = insurancecommon.getstrategyflightagencynew(appfltentity.directflightchannel);
//根据票台获得票台对应的城市
strategycityid = insurancecommon.getflightagencycity(strategyflightagency);
}
b.
if (isdirectflight &&
(this.corppaytype == expensetype.own ||
this.accountinfo.directordersquotemode == "i"))
{
strategyflightagency = insurancecommon.getstrategyflightagencynew(appfltentity.directflightchannel);
//根据票台获得票台对应的城市
strategycityid = insurancecommon.getflightagencycity(strategyflightagency);
}
3.使用三元表达式
a.
if (insuranceinfolist != null && insuranceinfolist.count > 0 && insuranceinfolist[0].generaldescription.contains("e路泰康"))
collections.set("iseldercanbuyinsurance", "t");
else
collections.set("iseldercanbuyinsurance", "f");
b.
collections.set("iseldercanbuyinsurance", insuranceinfolist != null && insuranceinfolist.count > 0 && insuranceinfolist[0].generaldescription.contains("e路泰康") ? "t" : "f");
4.使用蓝不大表达式
a.
insuranceinfolist = insuranceinfolist.findall(delegate(bookinginsuranceinfo iinfo)
{
return iinfo.typeid == "c2c30";
});
b.
insuranceinfolist = insuranceinfolist.findall(a => a.typeid == "c2c30");
5.使用switch表达式，见上面。
6.使用数组包含
a.
if (wsflt.productsource == 4 && !string.isnullorempty(wsflt.directflightchannel) && (wsflt.directflightchannel.toupper() == "ho-ws" or wsflt.directflightchannel.toupper() == "zh-ws" or wsflt.directflightchannel.toupper() == "xt-ws")
&& directflightcorporationlist != null && directflightcorporationlist.count > 0 && !directflightcorporationlist.contains(corporationid))
{
return false;
}
b.
if (wsflt.productsource == 4 &&
new list<string>() { "ho-ws", "cz-ws", "xt-ws" }.contains(wsflt.directflightchannel.trim().toupper()) &&
directflightcorporationlist != null &&
directflightcorporationlist.count > 0 &&
!directflightcorporationlist.contains(corporationid))
{
return false;
}
可以看到代码中也使用了缩进。
