.net - Get process ID of a client that connected to a named pipe server with C# -

i'm not sure if i'm not seeing it, or what? need know process id of client connected via named pipe server instance of namedpipeserverstream. such possible?

in meantime came function:

[dllimport("kernel32.dll", setlasterror = true)] internal static extern bool getnamedpipeclientprocessid(intptr pipe, out uint32 clientprocessid); public static uint32 getnamedpipeclientprocid(namedpipeserverstream pipeserver) {     //return:     //      = client process id connected via named pipe server, or     //      = 0 if error     uint32 nprocid = 0;     try     {         intptr hpipe = pipeserver.safepipehandle.dangerousgethandle();         getnamedpipeclientprocessid(hpipe, out nprocid);     }     catch     {         //error         nprocid = 0;     }      return nprocid; } 

i'm not strong in "dangerousgethandles" , "dllimports". i'm way better off win32, i'm using here.

the main problem code, not perform correct error handling. need check return value of getnamedpipeclientprocessid detect error.

[dllimport("kernel32.dll", setlasterror = true)] internal static extern bool getnamedpipeclientprocessid(intptr pipe, out uint clientprocessid); public static uint getnamedpipeclientprocid(namedpipeserverstream pipeserver) {     uint32 nprocid;     intptr hpipe = pipeserver.safepipehandle.dangerousgethandle();     if (getnamedpipeclientprocessid(hpipe, out nprocid))         return nprocid;     return 0; }
