Provides services for managing the queue of work items for a thread.
Assembly: System.Windows (in System.Windows.dll)
Thetype exposes the following members.
|BeginInvoke(Action)||Executes the specified delegate asynchronously on the thread the is associated with.|
|BeginInvoke(Delegate, Object())||Executes the specified delegate asynchronously with the specified array of arguments on the thread the is associated with.|
|CheckAccess||Determines whether the calling thread is the thread associated with this .|
|Equals(Object)||Determines whether the specified Object is equal to the current Object. (Inherited from Object.)|
|Finalize||Allows an object to try to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.)|
|GetHashCode||Serves as a hash function for a particular type. (Inherited from Object.)|
|GetType||Gets the Type of the current instance. (Inherited from Object.)|
|MemberwiseClone||Creates a shallow copy of the current Object. (Inherited from Object.)|
|ToString||Returns a string that represents the current object. (Inherited from Object.)|
The class currently provides support only for running code on the user interface (UI) thread from a non-UI thread. For example, you could update the UI after the device camera finishes capturing a photo. For more information about this scenario, see How to create a base camera app for Windows Phone 8.
You can access the object for the UI thread through the DependencyObject.Dispatcher properties. These are instance methods, but instances of these types are frequently inaccessible from non-UI threads.
You can call the CheckAccess method to determine whether the caller is on the UI thread. If the caller is not on the UI thread, you can call BeginInvoke to run the specified delegate on the UI thread.
