DataGrid.HitTestInfo.GetHashCode メソッド

DataGrid.HitTestInfo インスタンスのハッシュコードを取得します。

名前空間: System.Windows.Forms
アセンブリ: System.Windows.Forms (system.windows.forms.dll 内)
構文

Visual Basic (宣言)

Public Overrides Function
 GetHashCode As Integer

Visual Basic (使用法)

Dim instance As HitTestInfo
Dim returnValue As Integer

returnValue = instance.GetHashCode

public override int GetHashCode ()

C++

public:
virtual int GetHashCode () override

public int GetHashCode ()

JScript

public override function GetHashCode () : int

戻り値
対象のインスタンスのハッシュコード。

解説

このメソッドは、GetHashCode をオーバーライドします。

使用例

DataGrid.HitTestInfo のハッシュコードを出力する例を次に示します。

Visual Basic

Private Sub dataGrid1_MouseDown(ByVal
 sender As Object, ByVal
 e As System.Windows.Forms.MouseEventArgs)
    Dim newLine As String
 = ControlChars.Cr
    Console.WriteLine(newLine)
    Dim myHitTest As System.Windows.Forms.DataGrid.HitTestInfo
    ' Use the DataGrid control's HitTest method with the x and y properties.
    myHitTest = dataGrid1.HitTest(e.X, e.Y)
    Console.WriteLine(("Hashcode " & myHitTest.GetHashCode().ToString()))
End Sub 'dataGrid1_MouseDown

private void dataGrid1_MouseDown
(object sender, System.Windows.Forms.MouseEventArgs e)
{
   string newLine = "\n";
   Console.WriteLine(newLine);
   System.Windows.Forms.DataGrid.HitTestInfo myHitTest;
   // Use the DataGrid control's HitTest method with the x and y properties.
   myHitTest = dataGrid1.HitTest(e.X,e.Y);
   Console.WriteLine("Hashcode " + myHitTest.GetHashCode().ToString());
}

C++

private:
   void dataGrid1_MouseDown( Object^ /*sender*/,
      System::Windows::Forms::MouseEventArgs^ e )
   {
      String^ newLine = "\n";
      Console::WriteLine( newLine );
      System::Windows::Forms::DataGrid::HitTestInfo^ myHitTest;
      // Use the DataGrid control's HitTest method with the x and y
 properties.
      myHitTest = dataGrid1->HitTest( e->X, e->Y );
      Console::WriteLine( "Hashcode {0}", myHitTest->GetHashCode() );
   }
