TaskFactory.FromAsync<TArg1, TResult> Method (Func<TArg1, AsyncCallback, Object, IAsyncResult>, Func<IAsyncResult, TResult>, TArg1, Object)
Creates a Task<TResult> that represents a pair of begin and end methods that conform to the Asynchronous Programming Model pattern.
Assembly: mscorlib (in mscorlib.dll)
public Task<TResult> FromAsync<TArg1, TResult>( Func<TArg1, AsyncCallback, Object, IAsyncResult> beginMethod, Func<IAsyncResult, TResult> endMethod, TArg1 arg1, Object state )
The type of the first argument passed to the beginMethod delegate.
The type of the result available through the Task<TResult>.
- Type: System.Func<, AsyncCallback, Object, IAsyncResult>
The delegate that begins the asynchronous operation.
The first argument passed to the beginMethod delegate.
- Type: System.Object
An object containing data to be used by the beginMethod delegate.
The exception that is thrown when the beginMethod argument is null.
The exception that is thrown when the endMethod argument is null.
The beginMethod delegate is started on the thread that FromAsync is running on. This method throws any exceptions thrown by the beginMethod.
