Pago: What is a good pattern for using a Global Mutex in C#?
// unique id for global mutex - Global prefix means it is global to the machine
const string mutex_id = "Global\\{B1E7934A-F688-417f-8FCB-65C3985E9E27}";
static void Main(string[] args)
{
using (var mutex = new Mutex(false, mutex_id))
{
// edited by Jeremy Wiebe to add example of setting up security for multi-user usage
// edited by 'Marc' to work also on localized systems (don't use just "Everyone")
var allowEveryoneRule = new MutexAccessRule(new SecurityIdentifier(WellKnownSidType.WorldSid, null), MutexRights.FullControl, AccessControlType.Allow);
var securitySettings = new MutexSecurity();
securitySettings.AddAccessRule(allowEveryoneRule);
mutex.SetAccessControl(securitySettings);
//edited by acidzombie24
var hasHandle = false;
try
{
try
{
// note, you may want to time out here instead of waiting forever
//edited by acidzombie24
//mutex.WaitOne(Timeout.Infinite, false);
hasHandle = mutex.WaitOne(5000, false);
if (hasHandle == false) return;//another instance exist
}
catch (AbandonedMutexException)
{
// Log the fact the mutex was abandoned in another process, it will still get aquired
}
// Perform your work here.
}
finally
{
//edit by acidzombie24, added if statemnet
if (hasHandle)
mutex.ReleaseMutex();
}
}
}
Si desea sólo una instancia echar un vistazo a objeto mutex: http://stackoverflow.com/questions/819773/run-single-instance-of-an-application-using-mutex –
hay un problema con el uso de Mutex de esa manera, además a veces necesito reiniciar mi aplicación usando Application.Restart que entraría en conflicto con el patrón mutex. – Stacker
Así que, básicamente, su pregunta es: "¿Cómo puedo obtener todas las funciones mutex sin crear realmente un mutex"? ¿Por qué no preguntas cómo solucionar los problemas que tienes con el uso de un mutex? –
