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.

Property Value
Type	Description
CancellationToken

Credentials

public CallCredentials? Credentials { get; }

Credentials to use for this call.

Property Value
Type	Description
CallCredentials

Deadline

public DateTime? Deadline { get; }

Call deadline.

Property Value
Type	Description
DateTime

Headers

public Metadata? Headers { get; }

Headers to send at the beginning of the call.

Property Value
Type	Description
Metadata

IsWaitForReady

public bool IsWaitForReady { get; }

If true and channel is in ChannelState.TransientFailure, the call will attempt waiting for the channel to recover instead of failing immediately (which is the default "FailFast" semantics). Note: experimental API that can change or be removed without any prior notice.

Property Value
Type	Description
bool

PropagationToken

public ContextPropagationToken? PropagationToken { get; }

Token for propagating parent call context.

Property Value
Type	Description
ContextPropagationToken

WriteOptions

public WriteOptions? WriteOptions { get; }

Write options that will be used for this call.

Property Value
