如何從vb.net中的數據表中選擇特定列？

Question

我有一個數據表，我根據條件過濾數據，但如何僅顯示數據表中的特定列？

Dim Dt As New DataTable 
       Dim SQlDa As SqlDataAdapter = New SqlDataAdapter(SqlCmd) 
       SQlDa.Fill(TrackingDt) 
       Dim Rows() As DataRow = Dt.Select("State = " + "'" + State + "'") 
       Dim TempDt As New DataTable 
       If Rows.Length > -1 Then 
        TempDt = Rows.CopyToDataTable() 
       End If 


       Return TempDt 

Answer 1

Dim view As New DataView(MyDataTable) 
Dim distinctValues As DataTable = view.ToTable(True, "ColumnA") 

Answer 2

嘗試這個

TempDt =New DataView(Rows.CopyToDataTable()).ToTable(False, 
"columnname1", "name2","...","..")
