推荐答案

轻松！ （当你知道如何......：笑:)。

只需设置ToolboxBitmap属性：

Easy! (When you know how... :laugh: )
Just set the ToolboxBitmap property:

[System.Drawing.ToolboxBitmap(@"C:\Projects\Controls\SQLControl.bmp")]
partial class ctrlSQL : UserControl
    {

注意：它必须是16x16 bmp： http：// msdn .microsoft.com / zh-cn / library / 4wk1wc0a.aspx [ ^ ]

解决方案1存在我在评论中解释的问题。更好的解决方案将是本页示例中显示的第三个解决方案：



http://msdn.microsoft.com/en-us/library/4wk1wc0a.aspx [ ^ ]。



请参阅： http://msdn.microsoft.com/en-us/library/system.drawing.toolboxbitmapattribute.aspx [ ^ ]。



应将16x16位图放入应用程序资源中。第一个例子（使用来自.NET FCL的控件类型）将起作用，但它没有什么实际意义。

因此，第三个例子说明了唯一具有实际意义的用法： http://msdn.microsoft.com/en-us/library/eth0sx9d.aspx [ ^ ]。



如果你使用这种方式，所讨论的位图总是带有定义所讨论控件的程序集，无论它如何部署;它可以使用应用程序构建或部署在IL代码中;解决方案的完整性无法破解。



真正的问题是MSDN对此功能的描述非常糟糕且有些误导，尤其是上面首先引用的页面。 br $>

The Solution 1 has the problem I explained in my comment to it. Better solution would be the 3rd one shown in the example on this page:

http://msdn.microsoft.com/en-us/library/4wk1wc0a.aspx[^].

Please see: http://msdn.microsoft.com/en-us/library/system.drawing.toolboxbitmapattribute.aspx[^].

The 16x16 bitmap should be put in the application resource. The first example (use of a control type from .NET FCL) will work, but it makes little practical sense.
So, the third example illustrate the only practically significant usage: http://msdn.microsoft.com/en-us/library/eth0sx9d.aspx[^].

If you use this way, the bitmap in question always come with the assembly defining the control in question, no matter how it is deployed; it could be built with the application or deployed in IL code; integrity of solution cannot be broken.

The real problem is that the MSDN description of this feature is really bad and somewhat misleading, especially the page referenced first, above.
