推荐答案

CodeProject上有很多按钮控件:

There are lots of button controls on CodeProject:

For example, this one:

0)Winforms-您必须创建一个自定义控件至少覆盖Paint事件.

1)WPF或Silverlight-您必须拿出自己的样式/数据模板并绘制所需的形状. (您也可以只创建图像并以自定义样式使用它.

2)ASP.Net-只需拿出具有所需形状的按钮图像，然后将其用作网页上的按钮即可.

最后，Google是您的朋友.

0) Winforms - You have to create a custom control that at least overrides the Paint event.

1) WPF or Silverlight - you have to come up with your own style/data template and draw the desired shape. (You could also just create an image and use that in your custom style.

2) ASP.Net - just come up with a button image with the desired shape, and use that as the button on your web page.

In the end, Google is your friend.
