如何避免System.Runtime.InteropServices.COMException？

Question

在我的Microsoft Surface项目中,我总是遇到很多以下异常:

在我停止程序之前,最后一次异常被抛出.我已经注释掉了我的所有代码,并且除了已经内置的代码之外,我运行了应用程序,但同样的情况也是如此.

我怎么能纠正这个？我只发现了这个参考:

http://www.mobydisk.com/softdev/techinfo/dotnetexceptions.html

它说:

从COM方法调用返回无法识别的HRESULT时引发的异常.

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异常.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()

Answer 1

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.

抛出异常时可以尝试中断.转到Debug> Exceptions ...并使用Find ...选项进行查找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.

Answer 2

我在System.Runtime.InteropServices.COMException打开项目解决方案时遇到了.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,异常消失了.
