C#编程实现DataTable添加行的方法

本文实例讲述了c#编程实现datatable添加行的方法。分享给大家供大家参考，具体如下：

方法一:

datatable tbldatas = new datatable("datas");
datacolumn dc = null;
dc = tbldatas.columns.add("id", type.gettype("system.int32"));
dc.autoincrement = true;//自动增加
dc.autoincrementseed = 1;//起始为1
dc.autoincrementstep = 1;//步长为1
dc.allowdbnull = false;//
dc = tbldatas.columns.add("product", type.gettype("system.string"));
dc = tbldatas.columns.add("version", type.gettype("system.string"));
dc = tbldatas.columns.add("description", type.gettype("system.string"));
datarow newrow;
newrow = tbldatas.newrow();
newrow["product"] = "水果刀";
newrow["version"] = "2.0";
newrow["description"] = "打架专用";
tbldatas.rows.add(newrow);
newrow = tbldatas.newrow();
newrow["product"] = "折叠凳";
newrow["version"] = "3.0";
newrow["description"] = "行走江湖七武器之一";
tbldatas.rows.add(newrow);

方法二:

datatable tbldatas = new datatable("datas");
tbldatas.columns.add("id", type.gettype("system.int32"));
tbldatas.columns[0].autoincrement = true;
tbldatas.columns[0].autoincrementseed = 1;
tbldatas.columns[0].autoincrementstep = 1;
tbldatas.columns.add("product", type.gettype("system.string"));
tbldatas.columns.add("version", type.gettype("system.string"));
tbldatas.columns.add("description", type.gettype("system.string"));
tbldatas.rows.add(new object[]{null,"a","b","c"});
tbldatas.rows.add(new object[] { null, "a", "b", "c" });
tbldatas.rows.add(new object[] { null, "a", "b", "c" });
tbldatas.rows.add(new object[] { null, "a", "b", "c" });
tbldatas.rows.add(new object[] { null, "a", "b", "c" });

希望本文所述对大家c#程序设计有所帮助。
