Type Parameters

T

The type to deserialize the digital twin to.

Parameters

digitalTwinId: String

The Id of the digital twin.

digitalTwin: T

The application/json digital twin to create.

ifNoneMatch: Nullable<ETag>

If-None-Match header that makes the request method conditional on a recipient cache or origin server either not having any current representation of the target resource. For more information about this property, see RFC 7232. Acceptable values are null or "". If ifNonMatch option is null the service will replace the existing entity with the new entity.

cancellationToken: CancellationToken

The cancellation token.

Returns

Task<Response<T>>

The created application/json digital twin and the HTTP response Response<T>.

Exceptions

RequestFailedException

The exception that captures the errors from the service. Check the ErrorCode and Status properties for more details.

ArgumentNullException

The exception is thrown when digitalTwinId or digitalTwin is null.

Examples

var customTwin = new CustomDigitalTwin
{
    Id = customDtId,
    Metadata = { ModelId = modelId },
    Prop1 = "Prop1 val",
    Prop2 = 987,
    Component1 = new MyCustomComponent
    {
        ComponentProp1 = "Component prop1 val",
        ComponentProp2 = 123,
    },
};
Response<CustomDigitalTwin> createCustomDigitalTwinResponse = await client.CreateOrReplaceDigitalTwinAsync(customDtId, customTwin);
Console.WriteLine($"Created digital twin '{createCustomDigitalTwinResponse.Value.Id}'.");
