推荐答案

创建自己的控件所需的最低限度是一个类继承自System.Windows.Forms.Control类.有了它后，如果您构建项目，则该项目应显示在工具箱中.如果要在其他项目中使用它，则将其编译为类库DLL，然后在VS中，右键单击工具箱"并选择选择项目"，然后浏览到您的DLL文件

您的课程将有一个Paint事件，您可以使用GDI +绘制任何事件；如果需要，您可以通过P/Invoke使用GDI.

任何公共属性都将显示在表单设计器的属性网格中.

希望对您有帮助

The minimum you need to create your own controls is a class that inherits from the System.Windows.Forms.Control class. Once you have this, if you build the project, it should appear in the toolbox. If you want to use it in other projects, compile it as a Class Library DLL, then in VS, right click in the Toolbox and select Choose Items, then Browse to your DLL file

Your class will have a Paint event, which you can use to draw whatever you need using GDI+; You can use GDI through P/Invoke if you want though.

Any public properties will show up in the property grid on the form designer.

Hope this helps
