Syntax

public sealed class AsyncUnaryCall<TResponse> : IDisposable

Type Parameters

Name	Description
TResponse	Response message type for this call.

Constructors

AsyncUnaryCall(Task<TResponse>, Func<Object, Task<Metadata>>, Func<Object, Status>, Func<Object, Metadata>, Action<Object>, Object)

Creates a new AsyncUnaryCall object with the specified properties.

Declaration

public AsyncUnaryCall(Task<TResponse> responseAsync, Func<object, Task<Metadata>> responseHeadersAsync, Func<object, Status> getStatusFunc, Func<object, Metadata> getTrailersFunc, Action<object> disposeAction, object state)

Parameters

Type	Name	Description
System.Threading.Tasks.Task<TResponse>	responseAsync	The response of the asynchronous call.
System.Func<System.Object, System.Threading.Tasks.Task<Metadata>>	responseHeadersAsync	Response headers of the asynchronous call.
System.Func<System.Object, Status>	getStatusFunc	Delegate returning the status of the call.
System.Func<System.Object, Metadata>	getTrailersFunc	Delegate returning the trailing metadata of the call.
System.Action<System.Object>	disposeAction	Delegate to invoke when Dispose is called on the call object.
System.Object	state	State object for use with the callback parameters.

AsyncUnaryCall(Task<TResponse>, Task<Metadata>, Func<Status>, Func<Metadata>, Action)

Creates a new AsyncUnaryCall object with the specified properties.

Declaration

public AsyncUnaryCall(Task<TResponse> responseAsync, Task<Metadata> responseHeadersAsync, Func<Status> getStatusFunc, Func<Metadata> getTrailersFunc, Action disposeAction)

Parameters

Type	Name	Description
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

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

ConfigureAwait(Boolean)

Configures an awaiter used to await this AsyncUnaryCall<TResponse>.

Declaration

public ConfiguredTaskAwaitable<TResponse> ConfigureAwait(bool continueOnCapturedContext)

Parameters

Type	Name	Description
System.Boolean	continueOnCapturedContext	true to attempt to marshal the continuation back to the original context captured; otherwise, false.

Returns

Type	Description
System.Runtime.CompilerServices.ConfiguredTaskAwaitable<TResponse>	An object used to await this task.

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()

Remarks

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

GetAwaiter()

Gets an awaiter used to await this AsyncUnaryCall<TResponse>.

Declaration

public TaskAwaiter<TResponse> GetAwaiter()

Returns

Type	Description
System.Runtime.CompilerServices.TaskAwaiter<TResponse>	An awaiter instance.

Remarks

This method is intended for compiler use rather than use directly in code.

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
