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：

最后一个异常一直抛出，直到我停止程序。我已经注释掉了所有代码，并且除了已经内置的代码之外什么都没有运行该应用程序，但同样的情况发生了。

我该如何纠正这个问题？我只找到了这个参考：

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

那里写着：

当发生异常时抛出的异常 返回无法识别的 HRESULT COM 方法调用。

但我不知道这意味着什么......

====编辑====

我按照下面答案中的建议来调试异常。这是详细的报告：

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: 

调试器在构造函数调用处停止：

 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停止：

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。如果你能找到这一点，那么你就成功了一半。

您可以尝试在引发异常时中断。转到调试>;异常...并使用查找...选项来定位System.Runtime.InteropServices.COMException。勾选抛出时中断的选项，然后调试应用程序。

希望它会在有意义的地方中断，并且您将能够追溯并找到错误的根源。

Answer 2

我在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权限来运行某些 COM 方法。我以管理员身份运行 Visual Studio，异常消失了。

Answer 3

我在将对象（变量）矩阵数组复制到 Excel 工作表时遇到此异常。解决方案是，矩阵数组索引(i,j) 必须从 (0,0) 开始，而 Excel 工作表应从 (1,1) 开始矩阵数组索引 (i,j) 。

我希望你有这个概念。

Answer 4

首先找到导致该异常的代码行，然后找到与该行相关的引用（dll）文件。然后尝试注册dll或ocx文件。
搜索cmd并以管理员身份运行。注册dll或ocx文件的命令是：

C:\Windows\SysWOW64\regsvr32.exe "drive:\folder\yourdll.ocx"

Answer 5

也许您正在尝试访问索引为 0 的 Excel，请注意 Excel 行/列从 1 开始。
