无法调试使用Process.Start（）开始的项目 [英] Can not debug a Project started using Process.Start()

问题描述

我有两个C＃WinForm项目在同一个解决方案中可以调用它们A和B.项目A通过下面的调用启动进程B.

  ProcessStartInfo psi = new ProcessStartInfo（）; 
 psi.FileName = Task.EXEFilename; 
 psi.WorkingDirectory = Path.GetDirectoryName（Data.EXEFilename）; 
 Process.Start（psi）; 
  

进程B正确启动。我正在调试过程B时调试过程B.我认为在B中设置一个断点就足够了，但是它永远不会被打。我已经验证了启动的进程是在B的bin / debug文件夹中。我不应该在这种情况下附加到进程以将调试从A切换到B？

解决方案

在第二个项目中，它检查其命令行参数，如果它看到类似于 - debug 被传入第一个参数第二个程序启动调试器本身

  private static void Main（string [] args）
 {
 //如果没有附加调试器，并且参数--debug被传递启动调试器
 if（args.Length == 1&& args [0] ==--debug& & Debugger.IsAttached == false）
 Debugger.Launch（）; 
 
 //（snip）你的程序的其余部分
 
} 
  

当您执行此操作时，您将看到一个对话框窗口，您可以选择打开Visual Studio的新副本或仅使用已打开的副本。

您还可以将子进程放在图像文件执行选项注册表项。

I have two C# WinForm projects in the same solution lets call them A and B. Project A starts Process B via a call like below

ProcessStartInfo psi = new ProcessStartInfo();
psi.FileName = Task.EXEFilename;
psi.WorkingDirectory = Path.GetDirectoryName(Data.EXEFilename);
Process.Start(psi);

The process B is started correctly. I wanted to debug the process B while I am debugging A. I thought putting a break point in the B would be enough but it is never hit. I have verified that process that is started is in the bin/debug folder of the B. I should not be doing attached to process in this case to switch debugging from A to B ?

解决方案

In the 2nd project have it check its command line arguments, if it sees something like --debug was passed in as the first argument the 2nd program launches the debugger itself

private static void Main(string[] args)
{
    //If no debugger is attached and the argument --debug was passed launch the debugger
    if (args.Length == 1 && args[0] == "--debug" && Debugger.IsAttached == false)
        Debugger.Launch();

    //(snip) the rest of your program

}

When you do this you will get a dialog window that will allow you to choose to open a new copy of Visual Studio or just use your already open copy.

You can also put the child process in the Image File Execution Options registry key.
