Syntax

public sealed class AsyncClientStreamingCall<TRequest, TResponse> : IDisposable

Type Parameters

Name	Description
TRequest	Request message type for this call.
TResponse	Response message type for this call.

Constructors

AsyncClientStreamingCall(IClientStreamWriter<TRequest>, Task<TResponse>, Task<Metadata>, Func<Status>, Func<Metadata>, Action)

Creates a new AsyncClientStreamingCall object with the specified properties.

Declaration

public AsyncClientStreamingCall(IClientStreamWriter<TRequest> requestStream, Task<TResponse> responseAsync, Task<Metadata> responseHeadersAsync, Func<Status> getStatusFunc, Func<Metadata> getTrailersFunc, Action disposeAction)

Parameters

Type	Name	Description
IClientStreamWriter<TRequest>	requestStream	Stream of request values.
System.Threading.Tasks.Task<TResponse>	responseAsync	The response of the asynchronous call.
System.Threading.Tasks.Task<Metadata>	responseHeadersAsync	Response headers of the asynchronous call.
System.Func<Status>	getStatusFunc	Delegate returning the status of the call.
System.Func<Metadata>	getTrailersFunc	Delegate returning the trailing metadata of the call.
System.Action	disposeAction	Delegate to invoke when Dispose is called on the call object.

Properties

RequestStream

Async stream to send streaming requests.

Declaration

public IClientStreamWriter<TRequest> RequestStream { get; }

Property Value

Type	Description
IClientStreamWriter<TRequest>

ResponseAsync

Asynchronous call result.

Declaration

public Task<TResponse> ResponseAsync { get; }

Property Value

Type	Description
System.Threading.Tasks.Task<TResponse>

ResponseHeadersAsync

Asynchronous access to response headers.

Declaration

public Task<Metadata> ResponseHeadersAsync { get; }

Property Value

Type	Description
System.Threading.Tasks.Task<Metadata>

Methods

Dispose()

Provides means to cleanup after the call. If the call has already finished normally (request stream has been completed and call result has been received), 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.

Declaration

public void Dispose()

Implements

System.IDisposable.Dispose()

Remarks

Normally, there is no need for you to dispose the call unless you want to utilize the "Cancel" semantics of invoking Dispose.

GetAwaiter()

Allows awaiting this object directly.

Declaration

public TaskAwaiter<TResponse> GetAwaiter()

Returns

Type	Description
System.Runtime.CompilerServices.TaskAwaiter<TResponse>

GetStatus()

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

Declaration

public Status GetStatus()

Returns

Type	Description
Status

GetTrailers()

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

Declaration

public Metadata GetTrailers()

Returns

Type	Description
Metadata
