关于dataTable中根据列排序正确姿势做个随笔，方便查阅
1 System.Data.DataTable dt = new System.Data.DataTable();
2 dt.Columns.Add("date", typeof(System.String));
3 System.Data.DataRow dr = dt.NewRow();
4 dr["date"] = "2016-09";
5 System.Data.DataRow dr1 = dt.NewRow();
6 dr1["date"] = "2015-09";
7 System.Data.DataRow dr2 = dt.NewRow();
8 dr2["date"] = "2014-09";
9 System.Data.DataRow dr3 = dt.NewRow();
10 dr3["date"] = "2016-06";
11 System.Data.DataRow dr4 = dt.NewRow();
12 dr4["date"] = "2013-10";
13 dt.Rows.Add(dr);
14 dt.Rows.Add(dr1);
15 dt.Rows.Add(dr2);
16 dt.Rows.Add(dr3);
17 dt.Rows.Add(dr4);
18 System.Data.DataView dv = dt.DefaultView;
19 dv.Sort = "date";
20 System.Data.DataTable dt1 = dv.ToTable();
21
22 foreach (System.Data.DataRow varDr in dt1.Rows)
23 {
24 Console.WriteLine(varDr["date"].ToString());
25 }
