属性

次の例では、テーブルを DataView 2 つの列で並べ替えるよう指示します。

using System.Data;
using System;
public class A {
   static void Main(string[] args) {
      DataTable locationTable = new DataTable("Location");
      // Add two columns
      locationTable.Columns.Add("State");
      locationTable.Columns.Add("ZipCode");

      // Add data
      locationTable.Rows.Add("Washington", "98052");
      locationTable.Rows.Add("California", "90001");
      locationTable.Rows.Add("Hawaii", "96807");
      locationTable.Rows.Add("Hawaii", "96801");
      locationTable.AcceptChanges();

      Console.WriteLine("Rows in original order\n State \t\t ZipCode");
      foreach (DataRow row in locationTable.Rows) {
         Console.WriteLine(" {0} \t {1}", row["State"], row["ZipCode"]);
      }

      // Create DataView
      DataView view = new DataView(locationTable);

      // Sort by State and ZipCode column in descending order
      view.Sort = "State ASC, ZipCode ASC";

      Console.WriteLine("\nRows in sorted order\n State \t\t ZipCode");
      foreach (DataRowView row in view) {
         Console.WriteLine(" {0} \t {1}", row["State"], row["ZipCode"]);
      }
   }
}
Imports System.Data
Public Class A
   Public Shared Sub Main(args As String())
      Dim locationTable As New DataTable("Location")
      ' Add two columns
      locationTable.Columns.Add("State")
      locationTable.Columns.Add("ZipCode")

      ' Add data 
      locationTable.Rows.Add("Washington", "98052")
      locationTable.Rows.Add("California", "90001")
      locationTable.Rows.Add("Hawaii", "96807")
      locationTable.Rows.Add("Hawaii", "96801")
      locationTable.AcceptChanges()

      Console.WriteLine("Rows in original order" & vbLf & " State " & vbTab & vbTab & " ZipCode")
      For Each row As DataRow In locationTable.Rows
         Console.WriteLine(" {0} " & vbTab & " {1}", row("State"), row("ZipCode"))
      Next

      ' Create DataView
      Dim view As New DataView(locationTable)

      ' Sort by State and ZipCode column in descending order
      view.Sort = "State ASC, ZipCode ASC"

      Console.WriteLine(vbLf & "Rows in sorted order" & vbLf & " State " & vbTab & vbTab & " ZipCode")
      For Each row As DataRowView In view
         Console.WriteLine(" {0} " & vbTab & " {1}", row("State"), row("ZipCode"))
      Next
   End Sub
End Class
