[<ExtensionAttribute>]
static member Select : 
        task : Task<'TSource> * 
        continuationAction : Action<Task<'TSource>> * 
        supportsErrors : bool -> Task 

Parameters

task

Type: System.Threading.TasksTaskTSource
The antecedent task.

continuationAction

Type: SystemActionTaskTSource
The continuation action to execute when task completes.

supportsErrors

Type: SystemBoolean
if the continuationAction properly handles a faulted antecedent task; otherwise, .

Type Parameters

TSource

The type of the result produced by the antecedent TaskTResult.

Return Value

Usage Note

This code implements support for the following construct without requiring the use of /.

try
{
    TSource source = await task.ConfigureAwait(false);
}
catch
{
    if (!supportsErrors)
        throw;
}

continuationAction(task);

If the antecedent task is canceled, or faulted with supportsErrors set to , the status of the antecedent is directly applied to the task returned by this method; it is not wrapped in an additional AggregateException.

Notes to Callers
Since the continuation is executed synchronously, this method should only be used for lightweight continuation actions. For non-trivial continuation actions, use ThenTSource(TaskTSource, FuncTaskTSource, Task, Boolean) instead.
