public struct CallOptions

Options for calls made by client.

Namespace

Grpc.Core

Assembly

Grpc.Core.Api.dll

Constructors

CallOptions(Metadata?, DateTime?, CancellationToken, WriteOptions?, ContextPropagationToken?, CallCredentials?)

public CallOptions(Metadata? headers = null, DateTime? deadline = null, CancellationToken cancellationToken = default, WriteOptions? writeOptions = null, ContextPropagationToken? propagationToken = null, CallCredentials? credentials = null)

Creates a new instance of CallOptions struct.

Parameters
Name Description
headers Metadata

Headers to be sent with the call.

deadline DateTime

Deadline for the call to finish. null means no deadline.

cancellationToken CancellationToken

Can be used to request cancellation of the call.

writeOptions WriteOptions

Write options that will be used for this call.

propagationToken ContextPropagationToken

Context propagation token obtained from ServerCallContext.

credentials CallCredentials

Credentials to use for this call.

Properties

CancellationToken

public CancellationToken CancellationToken { get; }

Token that can be used for cancelling the call on the client side. Cancelling the token will request cancellation of the remote call. Best effort will be made to deliver the cancellation notification to the server and interaction of the call with the server side will be terminated. Unless the call finishes before the cancellation could happen (there is an inherent race), the call will finish with StatusCode.Cancelled status.
