SemaphoreSlim.Wait Method (Int32)

Blocks the current thread until it can enter the SemaphoreSlim, using a 32-bit signed integer that specifies the timeout.

Namespace:  System.Threading
Assemblies:   System.Threading (in System.Threading.dll)
  mscorlib (in mscorlib.dll)

public bool Wait(
	int millisecondsTimeout
)

Parameters

millisecondsTimeout
Type: System.Int32

The number of milliseconds to wait, or Infinite(-1) to wait indefinitely.

Return Value

Type: System.Boolean
true if the current thread successfully entered the SemaphoreSlim; otherwise, false.

ExceptionCondition
ArgumentOutOfRangeException

millisecondsTimeout is a negative number other than -1, which represents an infinite time-out.

If a thread or task is able to enter the semaphore, it decrements the CurrentCount property by one.

If a thread or task is blocked when calling Wait(Int32), and the time-out interval specified by millisecondsTimeout expires, the thread or task doesn’t enter the semaphore, and the CurrentCount property isn’t decremented.
