範例

• 下列範例的設計目的是要與 Windows Forms 搭配使用，而且需要 PaintEventArgse，這是 Paint 事件處理程式的參數。 程式代碼範例示範如何使用某個 RegionData 物件的 Data，為另一個 RegionData設定 Data。

C#

private void DemonstrateRegionData2(PaintEventArgs e)
{

    //Create a simple region.
    Region region1 = new Region(new Rectangle(10, 10, 100, 100));

    // Extract the region data.
    System.Drawing.Drawing2D.RegionData region1Data = region1.GetRegionData();
    byte[] data1;
    data1 = region1Data.Data;

    // Create a second region.
    Region region2 = new Region();

    // Get the region data for the second region.
    System.Drawing.Drawing2D.RegionData region2Data = region2.GetRegionData();

    // Set the Data property for the second region to the Data from the first region.
    region2Data.Data = data1;

    // Construct a third region using the modified RegionData of the second region.
    Region region3 = new Region(region2Data);

    // Dispose of the first and second regions.
    region1.Dispose();
    region2.Dispose();

    // Call ExcludeClip passing in the third region.
    e.Graphics.ExcludeClip(region3);

    // Fill in the client rectangle.
    e.Graphics.FillRectangle(Brushes.Red, this.ClientRectangle);

    region3.Dispose();
}
