如何在c#.net中制作圆形窗口形式

how to make a round window form in c# .net

推荐答案

我假设您是在谈论Windows形式的圆角.
C#Winforms中的圆角表格. [ ^ ]

您可以使用Graphics类来覆盖Onpaint
表格的方法(在表格上打印的地方)，您可能需要阅读以下内容
使用GDI类.
这是 GDI +初学者教程 [ Rectangle.Round方法 [ ^ ]供参考.

I assume you''re talking about rounded corners for windows forms.
Rounded Corner Form in C# Winforms.[^]

You can use the classes of Graphics to override the Onpaint
method of the form ( where the form is printed ) you may need to read about
using GDI classes.
Here is good example on GDI+ Tutorial for Beginners[^]

Also have a look on Rectangle.Round Method[^] for reference.

protected void RePaint()
{
   GraphicsPath graphicpath = new graphicsPath();
    graphicpath.StartFigure();
    graphicpath.AddArc(0,0,25,25,180,90);
    graphicpath.AddLine(25,0,this.Width-25,0); 
    graphicpath.AddArc(this.Width-25,0,25,25,270,90); 
    graphicpath.AddLine(this.Width,25,this.Width,this.Height-25);
    graphicpath.AddArc(this.Width-25,this.Height-25,25,25,0,90);
    graphicpath.AddLine(this.Width-25,this.height,25,this.Height);
    graphicpath.AddArc(0,this.Height-25,25,25,90,90);
    graphicpath.CloseFigure();
    this.Region = new Region(graphicpath)
}

那不是太困难-您所需要做的就是修改Region属性:

That''s not too difficult - all you need to do is modify the Region property:

GraphicsPath path = new GraphicsPath();
path.AddEllipse(new Rectangle(0, 0, 300, 300));
Region = new Region(path);

但是，这从来没有那么简单！如果您制作圆形(甚至按钮)，则必须自己绘制所有图形:标题栏，关闭按钮，边框，拉伸箭头，批次.

However, it is never that simple! If you make a round form (or even button) you are going to have to do all the drawing yourself: title bar, close button, borders, stretch arrows, the lot.
