TaskAwaiter Structure

.NET Framework 4.6 and 4.5

This API supports the .NET Framework infrastructure and is not intended to be used directly from your code.

Provides an object that waits for the completion of an asynchronous task.

Namespace:  System.Runtime.CompilerServices
Assemblies:   mscorlib (in mscorlib.dll)
  System.Threading.Tasks (in System.Threading.Tasks.dll)

[HostProtectionAttribute(SecurityAction.LinkDemand, Synchronization = true, 
	ExternalThreading = true)]
public struct TaskAwaiter : ICriticalNotifyCompletion, 

The TaskAwaiter type exposes the following members.

Public propertyIsCompletedGets a value that indicates whether the asynchronous task has completed.

Public methodEqualsIndicates whether this instance and a specified object are equal. (Inherited from ValueType.)
Public methodGetHashCodeReturns the hash code for this instance. (Inherited from ValueType.)
Public methodGetResultEnds the wait for the completion of the asynchronous task.
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Public methodOnCompletedSets the action to perform when the TaskAwaiter object stops waiting for the asynchronous task to complete.
Public methodToStringReturns the fully qualified type name of this instance. (Inherited from ValueType.)
Public methodUnsafeOnCompletedSchedules the continuation action for the asynchronous task that is associated with this awaiter.

This type and its members are intended for use by the compiler.


The HostProtectionAttribute attribute applied to this type or member has the following Resources property value: Synchronization | ExternalThreading. The HostProtectionAttribute does not affect desktop applications (which are typically started by double-clicking an icon, typing a command, or entering a URL in a browser). For more information, see the HostProtectionAttribute class or SQL Server Programming and Host Protection Attributes.
