窗体继承发生错误

[adventurous]

namespace MyNewsReader.UI
{
public partial class ChannelInfoViewForm : ChannelInfoFormBase
{
public ChannelInfoViewForm()
{
InitializeComponent();
}
}
}
我在继承channelInfoFormBase窗体时发生错误，这个窗体中就有几个文本框和按钮控件，现在一打开channelInfoViewForm
的窗体设计器就会出现错误提示

提示什么?

[adventurous]

The designer could not be shown for this file because none of the classes within it can be designed. The designer inspected the following classes in the file: ChannelInfoViewForm --- The base class 'MyNewsReader.UI.ChannelInfoFormBase' could not be loaded. Ensure the assembly has been referenced and that all projects have been built.

我还不太清楚继承一个窗体的步骤是什么，如果说一下可能我能找出错误

派生类找不到基类ChannelInfoFormBase
，须要正确的使用命名空间。

namespace MyNewsReader.UI
{
public partial class ChannelInfoViewForm : MyNewsReader.UI.ChannelInfoFormBase

public ChannelInfoViewForm()
{

}
}
这样算加上命名空间了吧，但还是不行

检查一下你ChannelInfoFormBase 的构造器，是否有designer识别不了的

vs2005的bug，不必理它。设计界面的时候可以是先继承form,要调试时再改回来

ChannelInfoFormBase好像有designer构造器，我用的是vs2008
