public Task<TNewResult> ContinueWith<TNewResult>( Func<Task<TResult>, Object, TNewResult> continuationFunction, Object state, TaskContinuationOptions continuationOptions )
The type of the result produced by the continuation.
- Type: System.Func<Task<TResult>, Object, >
A function to run when the Task<TResult> completes. When run, the delegate will be passed the completed task and the caller-supplied state object as arguments.
- Type: System.Object
An object representing data to be used by the continuation function.
The returned Task<TResult> will not be scheduled for execution until the current task has completed, whether it completes due to running to completion successfully, faulting due to an unhandled exception, or exiting out early due to being canceled.
The continuationFunction, when executed, should return a Task<TResult>. This task's completion state will be transferred to the task returned from the ContinueWith call.
