ManualResetEvent Constructor

Updated: March 2011

Initializes a new instance of the ManualResetEvent class with a Boolean value indicating whether to set the initial state to signaled.

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

public ManualResetEvent(
	bool initialState
)

Parameters

initialState
Type: System.Boolean
true to set the initial state signaled; false to set the initial state to nonsignaled.

If the initial state of a ManualResetEvent is signaled (that is, if it is created by passing true for initialState), threads that wait on the ManualResetEvent do not block. If the initial state is nonsignaled, threads block until the Set method is called.
