Hi

I Using this code for draw a pic. Link:

Dim x As Integer = 2
        Dim y As Integer = 2
        Dim w As Integer = 400
        Dim h As Integer = 400
        Dim r As Integer = 30



        Dim path As GraphicsPath = New GraphicsPath()
        path.AddArc(x, y, r, r, 180, 90)
        path.AddLine(x + r, y, x + w - r, y)

        path.CloseFigure()

推荐答案

只需使用Graphics.DrawPath:

Just use Graphics.DrawPath:

Dim x As Integer = 2
Dim y As Integer = 2
Dim w As Integer = 400
'int h = 400;
Dim r As Integer = 30

Dim path As New System.Drawing.Drawing2D.GraphicsPath()
path.AddArc(x, y, r, r, 180, 90)
path.AddLine(x + r, y, x + w - r, y)

path.CloseFigure()
g.DrawPath(Pens.Red, path)

如果要处理Paint事件，则可以从PaintEventArgs参数Graphics属性获取上下文.否则，您需要为要绘制的项目创建Graphics对象，并在完成后将其处理.

If you are handling the Paint event, your can get the context from the PaintEventArgs parameters Graphics property. Otherwise you need to create the Graphics object for the item you are drawing onto, and Dispose it when you are finished.
