Açıklamalar

Yönetilen bir iş parçacığı oluşturulduğunda, iş parçacığında yürütülen yöntem, oluşturucuya Thread geçirilen bir ThreadStart temsilci veya temsilci ParameterizedThreadStart tarafından temsil edilir. yöntemi çağrılana Thread.Start kadar iş parçacığı yürütülmeye başlamaz. Yürütme, veya ParameterizedThreadStart temsilcisi tarafından temsil edilen yöntemin ThreadStart ilk satırında başlar.
