无法打开我的C#项目

Vel*_*gan 0 .net c# visual-studio-2008

我无法在Visual Studio 2008中打开我的项目.它是由我的朋友用C#开发的.它显示了这个错误:

  "Could not find type 'LibrarySystem.ctrlSeparator'.
  Please make sure that the assembly that contains this type is referenced.
  If this type is a part of your development project, make sure that
  the project has been successfully built. "

  "The variable 'ctrlSeparator1' is either undeclared or was never assigned. "

我该如何纠正这个问题?

尊重......错误信息告诉你需要知道的一切......

它正在尝试加载一个不存在的控件.所以要么你的朋友没有给你整个项目,要么他使用了你没有的第三方组件.
