C#在DataTable中使用LINQ

 1 private static DataTable GetStuTable()
 2         {
 3 
 4             int[] id = { 4, 5, 1, 3, 2, 7, 6 };
 5             string[] name = {"Tom","Jack","HelloWorld","Visual Studio","Gril","Timmy","Geo" };
 6             DataTable table = new DataTable("Student");
 7             table.Columns.Add("ID", typeof(int));
 8             table.Columns.Add("Name", typeof(string));
 9 
10             for(int i = 0;i< id.Length;i++)
11             {
12                 table.Rows.Add(new object[] { id[i],name[i]});
13             }
14 
15             return table;
16         }

 1 DataTable dt = GetNumbersTable();
 2 
 3             var students = dt.AsEnumerable();
 4 
 5             //排序
 6             var result = students.OrderBy(x => x.Field<int>("ID"));
 7 
 8             //输出
 9             Console.WriteLine("ID" + "\t" + "Name");
10             foreach (DataRow row in result)
11             {
12                 Console.WriteLine(row["ID"].ToString() + "\t" + row["Name"].ToString());
13             }
