C# 对象转XML 支持匿名类

在网上找了很多关于对象转xml的，大多不支持匿名类转换，今天在*找了一篇文章  但是有些许bug  已经修复

 1 public static class objecttoxml
 2     {
 3         private static readonly type[] writetypes = new[] {
 4         typeof(string), typeof(datetime),typeof(decimal), typeof(guid),
 5         };
 6         public static bool issimpletype(this type type)
 7         {
 8             return type.isprimitive || writetypes.contains(type) || type.isenum;
 9         }
10         public static xelement toxml(this object input)
11         {
12             return input.toxml(null);
13         }
14 
15         private static string getxmlelementattributename(propertyinfo info)
16         {
17             string attributename = "";
18 
19             var attr = info.getcustomattributes(true);
20             if (attr != null && attr.length > 0)
21             {
22                 
23                 foreach (var item in attr)
24                 {
25                     if (item is xmlelementattribute)
26                     {
27                         var temp = item as xmlelementattribute;
28                         attributename = temp.elementname;
29 
30                         
31                     }
32                     else if(item is xmlrootattribute)
33                     {
34                         var temp = item as xmlrootattribute;
35                         attributename = temp.elementname;
36                     }
37                 }
38             }
39             return attributename;
40         }
41 
42         private static object getpropertyvalue(object input, propertyinfo info)
43         {
44             if (info.propertytype.isenum)
45             {
46                 return (int)info.getvalue(input);
47             }
48             return info.getvalue(input);
49         }
50 
51         public static xelement toxml(this object input, string element)
52         {
53             if (input == null)
54                 return null;
55 
56             if (string.isnullorempty(element))
57                 element = "object";
58 
59             element = xmlconvert.encodename(element);
60             var ret = new xelement(element);
61 
62             if (input != null)
63             {
64                 var type = input.gettype();
65                 var props = type.getproperties();
66                 var elements = from prop in props
67                                let name = xmlconvert.encodename(getxmlelementattributename(prop) == "" ? prop.name : getxmlelementattributename(prop))
68                                let val = getpropertyvalue(input,prop)
69                                let value = prop.propertytype.issimpletype()
70                                     ? new xelement(name, val)
71                                     : val.toxml(name)
72                                where value != null
73                                select value;
74 
75                 ret.add(elements);
76             }
77 
78             return ret;
79         }
80     }

调用：

var model = new {
   name = "张三",
   age = 18 
};

model.toxml("requestparameter").tostring();

记得引入命名空间
