Is there a way to detect if a debugger is attached to another process from C#?
提问by Lucas Meijer
I have a program that Process.Start()another program, and it shuts it down after N seconds.
我有一个程序，Process.Start()另一个程序，它在 N 秒后关闭它。
Sometimes I choose to attach a debugger to the started program. In those cases, I don't want the process shut down after N seconds.
有时我选择将调试器附加到启动的程序。在这些情况下，我不希望进程在 N 秒后关闭。
I'd like the host program to detect if a debugger is attached or not, so it can choose to not shut it down.
我希望主机程序检测是否连接了调试器，因此它可以选择不关闭它。
Clarification: I'm not looking to detect if a debugger is attached to myprocess, I'm looking to detect if a debugger is attached to the process I spawned.
说明：我不是要检测调试器是否连接到我的进程，而是要检测调试器是否连接到我生成的进程。

You will need to P/Invokedown to CheckRemoteDebuggerPresent. This requires a handle to the target process, which you can get from Process.Handle.
您将需要P/Invoke到CheckRemoteDebuggerPresent。这需要目标进程的句柄，您可以从 Process.Handle 中获取该句柄。

I know this is old, but I was having the same issue and realized if you have a pointer to the EnvDTE, you can check if the process is in Dte.Debugger.DebuggedProcesses:
我知道这是旧的，但我遇到了同样的问题，并意识到如果你有一个指向 EnvDTE 的指针，你可以检查进程是否在Dte.Debugger.DebuggedProcesses 中：
foreach (EnvDTE.Process p in Dte.Debugger.DebuggedProcesses) {
if (p.ProcessID == spawnedProcess.Id) {
// stuff
}
}
The CheckRemoteDebuggerPresent call only checks if the process is being natively debugged, I believe - it won't work for detecting managed debugging.
CheckRemoteDebuggerPresent 调用仅检查进程是否正在本地调试，我相信 - 它不适用于检测托管调试。

The solution for me is Debugger.IsAttached as described here: http://www.fmsinc.com/free/NewTips/NET/NETtip32.asp
我的解决方案是 Debugger.IsAttached，如下所述：http: //www.fmsinc.com/free/NewTips/NET/NETtip32.asp

Is the currentprocess being debugged?
是目前正在调试的进程？
var isDebuggerAttached = System.Diagnostics.Debugger.IsAttached;
Is anotherprocess being debugged?
是否正在调试另一个进程？
Process process = ...;
bool isDebuggerAttached;
if (!CheckRemoteDebuggerPresent(process.Handle, out isDebuggerAttached)
{
// handle failure (throw / return / ...)
}
else
{
// use isDebuggerAttached
}
/// <summary>Checks whether a process is being debugged.</summary>
/// <remarks>
/// The "remote" in CheckRemoteDebuggerPresent does not imply that the debugger
/// necessarily resides on a different computer; instead, it indicates that the
/// debugger resides in a separate and parallel process.
/// <para/>
/// Use the IsDebuggerPresent function to detect whether the calling process
/// is running under the debugger.
/// </remarks>

[return: MarshalAs(UnmanagedType.Bool)]
private static extern bool CheckRemoteDebuggerPresent(
SafeHandle hProcess,
[MarshalAs(UnmanagedType.Bool)] ref bool isDebuggerPresent);
Within a Visual Studio extension
在 Visual Studio 扩展中
Process process = ...;
bool isDebuggerAttached = Dte.Debugger.DebuggedProcesses.Any(
debuggee => debuggee.ProcessID == process.Id);
