要繪製之矩形左上角的 X 座標。

y
Int32

要繪製之矩形左上角的 Y 座標。

範例

下列程式代碼範例是專為搭配 Windows Forms 使用而設計,而且需要 PaintEventArgse,這是 Paint 事件處理程式的參數。 程式代碼會執行下列動作:

  • 建立黑色畫筆。

  • 建立矩形的位置和大小。

  • 將矩形繪製到畫面。

public:
   void DrawRectangleInt( PaintEventArgs^ e )
   {
      // Create pen.
      Pen^ blackPen = gcnew Pen( Color::Black,3.0f );

      // Create location and size of rectangle.
      int x = 0;
      int y = 0;
      int width = 200;
      int height = 200;

      // Draw rectangle to screen.
      e->Graphics->DrawRectangle( blackPen, x, y, width, height );
   }
public void DrawRectangleInt(PaintEventArgs e)
{
             
    // Create pen.
    Pen blackPen = new Pen(Color.Black, 3);
             
    // Create location and size of rectangle.
    int x = 0;
    int y = 0;
    int width = 200;
    int height = 200;
             
    // Draw rectangle to screen.
    e.Graphics.DrawRectangle(blackPen, x, y, width, height);
}
Public Sub DrawRectangleInt(ByVal e As PaintEventArgs)

    ' Create pen.
    Dim blackPen As New Pen(Color.Black, 3)

    ' Create location and size of rectangle.
    Dim x As Integer = 0
    Dim y As Integer = 0
    Dim width As Integer = 200
    Dim height As Integer = 200

    ' Draw rectangle to screen.
    e.Graphics.DrawRectangle(blackPen, x, y, width, height)
End Sub
