AsyncInfo.Run<TProgress> Method (Func<CancellationToken, IProgress<TProgress>, Task>)
Creates and starts a Windows Runtime asynchronous action that includes progress updates, by using a function that generates a started task. The task can support cancellation and progress reporting.
Assembly: System.Runtime.WindowsRuntime (in System.Runtime.WindowsRuntime.dll)
public static IAsyncActionWithProgress<TProgress> Run<TProgress>( Func<CancellationToken, IProgress<TProgress>, Task> taskProvider )
The type that is used for progress notifications.
- Type: System.Func<CancellationToken, IProgress<>, Task>
A delegate that represents the function that creates and starts the task. The started task is represented by the Windows Runtime asynchronous action that is returned. The function is passed a cancellation token that the task can monitor to be notified of cancellation requests, and an interface for reporting progress; you can ignore either or both of these arguments if your task does not support progress reporting or cancellation.
Return ValueType: IAsyncActionWithProgress<>
A started Windows.Foundation.IAsyncActionWithProgress<TProgress> instance that represents the task that is generated by taskProvider.
This method passes a cancellation token to the function that is specified by taskProvider. This token provides a connection between Windows Runtime cancellation and .NET Framework task cancellation; if the action is canceled, the task is canceled. If your task does not support cancellation, ignore the token.
This method also passes an interface for reporting progress. The function that is specified by taskProvider can use this interface to report progress through the IAsyncActionWithProgress<TProgress> instance. If your task does not support progress reporting, ignore the interface.
