如何避免System.Runtime.InteropServices.COMException？
在我的Microsoft Surface项目中，我总是会遇到很多以下exception：

我该如何纠正？ 我只找到了这个参考：

它说：
从COM方法调用返回无法识别的HRESULT时引发的exception。
但我不知道这意味着什么….

我按照下面的答案中的建议来调试exception。 这是详细报告：
System.Runtime.InteropServices.COMException occurred Message=Class not registered (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG)) Source=Microsoft.Surface.Shell.ShellApi ErrorCode=-2147221164 StackTrace: at Microsoft.Surface.Shell.NativeMethods.CoCreateInstance(Guid rclsid, Object pUnkOuter, CLSCTX dwClsContext, Guid riid) InnerException:
debuger在构造函数调用时停止了：
public MainWindow() { InitializeComponent(); // Add handlers for Application activation events AddActivationHandlers(); // AssemblyParser parser = new AssemblyParser(); //parser.parse(); // DirSearch(@"C:\Users\Roflcoptr\Documents\Visual Studio 2008\Projects\TestClass.dll\"); }
我在构造函数的开头就停了下来：
public MainWindow()
您的代码（或您调用的某些代码）正在调用返回未知值的COM方法。 如果你能找到那么你就在那里。
抛出exception时可以尝试中断。 转到Debug> Exceptions …并使用Find …选项找到System.Runtime.InteropServices.COMException 。 勾选选项以在抛出时中断，然后调试应用程序。
希望它会破坏某个有意义的地方，你将能够追溯并找到错误的来源。
打开项目解决方案时遇到了System.Runtime.InteropServices.COMException 。 有时用户没有足够的priveleges来运行一些COM方法。 我以管理员身份运行Visual Studio，exception消失了。
