DigitalTwinsClient.PublishComponentTelemetry Method

Definition

Namespace:

Azure.DigitalTwins.Core

Assembly:

Azure.DigitalTwins.Core.dll

Package:

Azure.DigitalTwins.Core v1.4.0

Source:

DigitalTwinsClient.cs

Publishes telemetry from a digital twin's component synchronously. The result is then consumed by one or many destination endpoints (subscribers) defined under DigitalTwinsEventRoute. These event routes need to be set before publishing a telemetry message, in order for the telemetry message to be consumed.

public virtual Azure.Response PublishComponentTelemetry (string digitalTwinId, string componentName, string messageId, string payload, DateTimeOffset? timestamp = default, System.Threading.CancellationToken cancellationToken = default);

abstract member PublishComponentTelemetry : string * string * string * string * Nullable<DateTimeOffset> * System.Threading.CancellationToken -> Azure.Response
override this.PublishComponentTelemetry : string * string * string * string * Nullable<DateTimeOffset> * System.Threading.CancellationToken -> Azure.Response

Public Overridable Function PublishComponentTelemetry (digitalTwinId As String, componentName As String, messageId As String, payload As String, Optional timestamp As Nullable(Of DateTimeOffset) = Nothing, Optional cancellationToken As CancellationToken = Nothing) As Response
