System.Runtime.InteropServices (mscorlib.dll)

class

When a COM error occurs, .NET tries to map it to an exception in the .NET Framework and throws that exception. If the COM error does not map to any exception in the .NET Framework, this exception is thrown instead. It's the "couldn't find an exception" exception.

 public class  COMException  : ExternalException {  // Public Constructors  public  COMException  ( );    public  COMException  (string   message   );    public  COMException  (string   message   , Exception   inner   );    public  COMException  (string   message   , int   errorCode   );  // Protected Constructors  protected  COMException  (System.Runtime.Serialization.SerializationInfo   info   ,        System.Runtime.Serialization.StreamingContext   context   );  // Public Instance Methods  public override string  ToString  ( );  // overrides Exception  }
