'Declaration <SecuritySafeCriticalAttribute> _ Public Shared Sub TryEnter ( _ obj As Object, _ timeout As TimeSpan, _ ByRef lockTaken As Boolean _ )
- Type: System.Object
The object on which to acquire the lock.
- Type: System.TimeSpan
The amount of time to wait for the lock. A value of –1 millisecond specifies an infinite wait.
- Type: System.Boolean%
The result of the attempt to acquire the lock, passed by reference. The input must be false. The output is true if the lock is acquired; otherwise, the output is false. The output is set even if an exception occurs during the attempt to acquire the lock.
If the lock was not taken because an exception was thrown, the variable specified for the lockTaken parameter is false after this method ends. This allows the program to determine, in all cases, whether it is necessary to release the lock.
