.net - 创建互斥体会引发 DirectoryNotFoundException

Question

我正在尝试创建一个 named mutex ，但是当我调用构造函数时，我得到一个 DirectoryNotFoundException!为什么互斥锁试图访问文件系统，我如何知道什么是有效路径？互斥体是否应该放置在任何特定的目录中，它与名称有何对应？

编辑:我正在使用 Mutex(bool, string) 重载，异常(exception)情况是:

System.IO.DirectoryNotFoundException: Could not find a part of the path '<mutex name>'.
at System.IO.__Error.WinIOError(Int32 errorCode, String maybeFullPath)
at System.Threading.Mutex.<>c__DisplayClass3.<.ctor>b__0(Object userData)
at System.Runtime.CompilerServices.RuntimeHelpers.ExecuteCodeWithGuaranteedCleanup(TryCode code, CleanupCode backoutCode, Object userData)
at System.Threading.Mutex..ctor(Boolean initiallyOwned, String name, Boolean& createdNew, MutexSecurity mutexSecurity)
at System.Threading.Mutex..ctor(Boolean initiallyOwned, String name)

Answer 1

啊，找到问题所在了。我的互斥体名称中有 \ ，Windows 将其解释为路径字符。运行:

mutexName = mutexName.Replace(Path.DirectorySeparatorChar, '_');
