Properties
RequestStream
public IClientStreamWriter<TRequest> RequestStream { get; }
Async stream to send streaming requests.
ResponseHeadersAsync
public Task<Metadata> ResponseHeadersAsync { get; }
Asynchronous access to response headers.
ResponseStream
public IAsyncStreamReader<TResponse> ResponseStream { get; }
Async stream to read streaming responses.
Methods
Dispose()
public void Dispose()
Provides means to cleanup after the call. If the call has already finished normally (request stream has been completed and response stream has been fully read), doesn't do anything. Otherwise, requests cancellation of the call which should terminate all pending async operations associated with the call. As a result, all resources being used by the call should be released eventually.
Normally, there is no need for you to dispose the call unless you want to utilize the
"Cancel" semantics of invoking Dispose
.
GetStatus()
public Status GetStatus()
Gets the call status if the call has already finished. Throws InvalidOperationException otherwise.
GetTrailers()
public Metadata GetTrailers()
Gets the call trailing metadata if the call has already finished. Throws InvalidOperationException otherwise.
