我正在创建一个自定义文本框控件（CustomTextBox）。 我使用 ToolBoxBitmapAttribute 在Visual Studio工具箱中显示一个图标：
Hi, I''m creating a custom textbox control (CustomTextBox). I use a ToolBoxBitmapAttribute to show an icon in the Visual Studio Toolbox:
[ToolboxBitmap(typeof(TextBox))] public sealed class CustomTextBox : TextBox我尝试显示与文本框相同的图标作为 System.Windows的图标.Forms.TextBox 。 现在，我希望工具箱中的 TextBox 图标为我的 CustomTextBox ，但我看到了这个图标： www.codeproject/script/Membership/Uploads/8966127/ControlIcon.png [ ^ ] 所以，我也尝试了这段代码：
I try to show the same icon for my text box as the icon for the System.Windows.Forms.TextBox. Now, I''m expecting a TextBox icon in the toolbox for my CustomTextBox, but I see this icon: www.codeproject/script/Membership/Uploads/8966127/ControlIcon.png[^] So, I tried also this code:
[ToolboxBitmap(typeof(TextBox),"System.Windows.Forms.TextBox.bmp")] // System.Windows.Forms.TextBox.bmp is the resource name of the icon for the TextBox, according to my decompiler public sealed class CustomTextBox : TextBox但我仍然看到这个图标： www.codeproject/script/Membership/Uploads/8966127/ControlIcon.png [ ^ ] 如何显示 TextBox 对于我的 CustomTextBox i我的工具箱而不是其他图标？ 注意：我的 CustomTextBox 类在我的另一个程序集中Windows窗体项目，我用 CustomControl 添加对程序集的引用。 提前致谢。 主题更新（将''item''更改为''icon''）[/ Edit]
But I still see this icon: www.codeproject/script/Membership/Uploads/8966127/ControlIcon.png[^] How can I show the TextBox for my CustomTextBox in my tool box instead of the other icon? Note: my CustomTextBox class is in another assembly than my Windows Forms project, and I add a reference to the assembly with my CustomControl. Thanks in advance. Subject updated (changed ''item'' into ''icon'')[/Edit]
推荐答案尝试以下代码，它适用于我： Try following code, it works for me: [ToolboxBitmap(typeof(TextBox), "TextBox.bmp")] public sealed class CustomTextBox : TextBox { }
重新编译后不要忘记删除并再次将组件添加到工具箱中。
And don''t forget to remove and add again your component to toolbox after recompile.
