public abstract System.Threading.Tasks.Task<Microsoft.Azure.Cosmos.ResponseMessage> PatchItemStreamAsync (string id, Microsoft.Azure.Cosmos.PartitionKey partitionKey, System.Collections.Generic.IReadOnlyList<Microsoft.Azure.Cosmos.PatchOperation> patchOperations, Microsoft.Azure.Cosmos.PatchItemRequestOptions requestOptions = default, System.Threading.CancellationToken cancellationToken = default);

abstract member PatchItemStreamAsync : string * Microsoft.Azure.Cosmos.PartitionKey * System.Collections.Generic.IReadOnlyList<Microsoft.Azure.Cosmos.PatchOperation> * Microsoft.Azure.Cosmos.PatchItemRequestOptions * System.Threading.CancellationToken -> System.Threading.Tasks.Task<Microsoft.Azure.Cosmos.ResponseMessage>

Public MustOverride Function PatchItemStreamAsync (id As String, partitionKey As PartitionKey, patchOperations As IReadOnlyList(Of PatchOperation), Optional requestOptions As PatchItemRequestOptions = Nothing, Optional cancellationToken As CancellationToken = Nothing) As Task(Of ResponseMessage)

Parameters

id: String

The Cosmos item id

partitionKey: PartitionKey

The partition key for the item.

patchOperations: IReadOnlyList<PatchOperation>

Represents a list of operations to be sequentially applied to the referred Cosmos item.

requestOptions: PatchItemRequestOptions

(Optional) The options for the item request.

cancellationToken: CancellationToken

(Optional) CancellationToken representing request cancellation.

Returns

Task<ResponseMessage>

A Task containing a ResponseMessage which wraps a Stream containing the patched resource record.

Examples

PatchItemAsync<T>(String, PartitionKey, IReadOnlyList<PatchOperation>, PatchItemRequestOptions, CancellationToken)

Remarks

The item's partition key value is immutable. To change an item's partition key value you must delete the original item and insert a new item. The patch operations are atomic and are executed sequentially. By default, resource body will be returned as part of the response. User can request no content by setting EnableContentResponseOnWrite flag to false.
