Grpc.Core.AsyncDuplexStreamingCall<TRequest, TResponse>

public sealed class AsyncDuplexStreamingCall<TRequest, TResponse> : IDisposable

Return type for bidirectional streaming calls.

public IClientStreamWriter<TRequest> RequestStream { get; }

Async stream to send streaming requests.

public Task<Metadata> ResponseHeadersAsync { get; }

Asynchronous access to response headers.

public IAsyncStreamReader<TResponse> ResponseStream { get; }

Async stream to read streaming responses.

public AsyncDuplexStreamingCall(IClientStreamWriter<TRequest> requestStream, IAsyncStreamReader<TResponse> responseStream, Task<Metadata> responseHeadersAsync, Func<Status> getStatusFunc, Func<Metadata> getTrailersFunc, Action disposeAction)

Creates a new AsyncDuplexStreamingCall object with the specified properties.

public AsyncDuplexStreamingCall(IClientStreamWriter<TRequest> requestStream, IAsyncStreamReader<TResponse> responseStream, Func<object, Task<Metadata>> responseHeadersAsync, Func<object, Status> getStatusFunc, Func<object, Metadata> getTrailersFunc, Action<object> disposeAction, object state)

Creates a new AsyncDuplexStreamingCall object with the specified properties.

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.

public Status GetStatus()

Gets the call status if the call has already finished. Throws InvalidOperationException otherwise.

public Metadata GetTrailers()

Gets the call trailing metadata if the call has already finished. Throws InvalidOperationException otherwise.
