名称“ $ exception”在当前上下文中不存在 [英] The name '$exception' does not exist in the current context

问题描述

今天，我正在调试工作中的应用程序。我继续在我的一个catch块中设置一个断点，以便更详细地检查异常。

Today I was debugging an application in my work. I proceeded to set a breakpoint in one of my catch blocks in order to inspect an exception with more detail.

查看详细信息模态窗口正常打开，但是没有向我显示异常的详细信息，而是引发了一个奇怪的错误，一个我从未得到的错误，也不知道这意味着什么：

The View Detail modal window opens normally, but instead of showing me the details of the exception, it is throwing a strange error, one I never got, nor I know what it means:

错误提示：

名称 $ exception在当前上下文中不存在

The name '$exception' does not exist in the current context

这令人沮丧，因为我在catch块范围内，所以我应该能够看到我的异常。

This is frustating because I am within the catch block scope, so I should be able to see my exception.

重新启动应用程序之后，我设法对其进行调试。这是（到目前为止）我唯一一次遇到此错误。

After restarting my application, I managed to debug it just fine. This was the only time (so far) I got this error.

有人知道它的含义吗，我该如何解决（而不必重新启动应用程序）？

Does anyone know what it means and how can I fix it (without having to restart application)?

注意：我正在使用 Visual Studio 2012 Premium 。版本 11.0.61030.00更新4

推荐答案

尝试明确告诉编译器如何导入dll。例如：

Try explicitly to tell the compiler how to import the dll. Ex:

using System;
using System.Runtime.InteropServices;

namespace BitmapProcessingCs
{
    public static class NativeMethods
    {
        [DllImport("BitmapProcessingCpp.dll", CallingConvention = CallingConvention.Cdecl)]
        public static extern void GenerateBitmap(IntPtr src, int dimension);
    }
}
