c# – 如何获取有关异常的更多信息

前端之家收集整理的这篇文章主要介绍了c# – 如何获取有关异常的更多信息前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。
我在 Windows 7,64位的visual studio 2008上创建了一个解决方案.

有用.

当我将它移动到另一台机器上时,也赢得了7,64位,它几乎没有信息就崩溃了.

最初的问题是:

call was rejected by callee

然后我实现了这个解决方

how to properly GetTypeFromProgID for visual studio 2008

但是,现在我的问题是,当我在另一台机器上运行可执行文件时,程序立即崩溃并显示以下信息:

我将代码包装在try / catch中,但仍未收到正确的错误消息:

static void Main()
{
    try
    {
        EnvDTE80.DTE2 dte;
        object obj = null;
        System.Type t = null;

        // Get the ProgID for DTE 8.0.
        t = System.Type.GetTypeFromProgID("VisualStudio.DTE.9.0",true);
        // Create a new instance of the IDE.
        obj = System.Activator.CreateInstance(t,true);
        // Cast the instance to DTE2 and assign to variable dte.
        dte = (EnvDTE80.DTE2)obj;

        // Register the IOleMessageFilter to handle any threading
        // errors.
        MessageFilter.Register();
        // Display the Visual Studio IDE.
        dte.MainWindow.Activate();


        Application.EnableVisualStyles();
        Application.SetCompatibleTextRenderingDefault(false);

        Application.Run(new Form1());

        // For example,get a reference to the solution2 object
        // and do what you like with it.

        // All done,so shut down the IDE...
        dte.Quit();
        // and turn off the IOleMessageFilter.
        MessageFilter.Revoke();

    }
    catch (Exception e)
    {
        MessageBox.Show(e.ToString());
    }
}

如何确定异常发生的确切位置以及异常是什么?

我有一些非托管代码

        }

        // Done with the filter,close it.
        public static void Revoke()

            return 0;
        }

        int IOleMessageFilter.RetryRejectedCall(System.IntPtr
          hTaskCallee,int dwRejectType)
        {
            if (dwRejectType == 2)
            // flag = SERVERCALL_RETRYLATER.

            }
            // Too busy; cancel call.
            return -1;
        }

        int IOleMessageFilter.MessagePending(System.IntPtr hTaskCallee,int dwPendingType)
        {
            //Return the flag PENDINGMSG_WAITDEFPROCESS.
            return 2;
        }

        // Implement the IOleMessageFilter interface.
        [DllImport("Ole32.dll")]
        private static extern int
          CoRegisterMessageFilter(IOleMessageFilter newFilter,out 
          IOleMessageFilter oldFilter);
    }
    [ComImport(),Guid("00000016-0000-0000-C000-000000000046"),InterfaceTypeAttribute(ComInterfaceType.InterfaceIsIUnknown)]

    {
        [PreserveSig]
        int HandleInComingCall(
            int dwCallType,IntPtr hTaskCaller,IntPtr lpInterfaceInfo);

        [PreserveSig]

            IntPtr hTaskCallee,int dwPendingType);
    }
}

在给我带来麻烦的机器上安装VS 2008 express后,我现在得到这个:

解决方法

您还可以尝试订阅AppDomain.CurrentDomain.UnhandledException事件:
AppDomain.CurrentDomain.UnhandledException += 
      (sender,e) => MessageBox.Show(e.ExceptionObject.ToString());

在Main方法的顶部执行此操作.
