示例
下面的代码示例演示如何在运行时创建位图,并通过设置Image属性将其显示在其中PictureBox。 若要运行此示例,请将其粘贴到Windows窗体中,并从窗体的构造函数调用CreateBitmapAtRuntime
。
PictureBox pictureBox1 = new PictureBox();
public void CreateBitmapAtRuntime()
{
pictureBox1.Size = new Size(210, 110);
this.Controls.Add(pictureBox1);
Bitmap flag = new Bitmap(200, 100);
Graphics flagGraphics = Graphics.FromImage(flag);
int red = 0;
int white = 11;
while (white <= 100) {
flagGraphics.FillRectangle(Brushes.Red, 0, red, 200,10);
flagGraphics.FillRectangle(Brushes.White, 0, white, 200, 10);
red += 20;
white += 20;
}
pictureBox1.Image = flag;
}
Private pictureBox1 As New PictureBox()
Public Sub CreateBitmapAtRuntime()
pictureBox1.Size = New Size(210, 110)
Me.Controls.Add(pictureBox1)
Dim flag As New Bitmap(200, 100)
Dim flagGraphics As Graphics = Graphics.FromImage(flag)
Dim red As Integer = 0
Dim white As Integer = 11
While white <= 100
flagGraphics.FillRectangle(Brushes.Red, 0, red, 200, 10)
flagGraphics.FillRectangle(Brushes.White, 0, white, 200, 10)
red += 20
white += 20
End While
pictureBox1.Image = flag
End Sub
注解
Image 属性设置为要显示的 Image。 可以在设计时或运行时执行此操作。
备注
如果要在多个 PictureBox 控件中使用同一个映像,请为每个 PictureBox控件创建映像的克隆。 从多个控件访问同一映像会导致发生异常。
