用户控件的数据源

更简单的选择可能是使用属性提供程序:

[AttributeProvider(typeof(IListSource))]

您可以尝试使用程序集限定名称吗？并指定编辑器？

[TypeConverter("System.Windows.Forms.Design.DataSourceConverter, System.Design, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a")]
[Editor("System.Windows.Forms.Design.DataSourceListEditor, System.Design, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a", "System.Drawing.Design.UITypeEditor, System.Drawing, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a")]

实际上,只需指定程序集,就可以将其缩写为与版本无关:

[TypeConverter("System.Windows.Forms.Design.DataSourceConverter, System.Design")]
[Editor("System.Windows.Forms.Design.DataSourceListEditor, System.Design", typeof(UITypeEditor))]
