c # sorted according to the specified column

C # provides built-in objects DataTable is particularly strong, if we need a column in the DataTable sort how to deal with it, the specific code as follows: 
DataTable dt = new new DataTable (); 
dt.Columns.Add ( "Id"); 
dt .Columns.Add ( "the Name"); 
dt.Rows.Add (new new Object [] {. 1, "zhangsan"}); 
dt.Rows.Add (new new Object [] {2, "taoge"}); 

dt. DefaultView.Sort = "Id DESC"; // Id by reverse 
dt.DefaultView.Sort = "Id DESC, Name desc "; // Name reverse and reverse by Id 
dt = dt.DefaultView.ToTable (); // return a new DataTable
