CosmosContainer.UpsertItemStreamAsync 方法

定义

在 Azure Cosmos 服务中将项流作为异步操作更新插入。

public abstract System.Threading.Tasks.Task<Azure.Response> UpsertItemStreamAsync (System.IO.Stream streamPayload, Azure.Cosmos.PartitionKey partitionKey, Azure.Cosmos.ItemRequestOptions requestOptions = default, System.Threading.CancellationToken cancellationToken = default);
abstract member UpsertItemStreamAsync : System.IO.Stream * Azure.Cosmos.PartitionKey * Azure.Cosmos.ItemRequestOptions * System.Threading.CancellationToken -> System.Threading.Tasks.Task<Azure.Response>
Public MustOverride Function UpsertItemStreamAsync (streamPayload As Stream, partitionKey As PartitionKey, Optional requestOptions As ItemRequestOptions = Nothing, Optional cancellationToken As CancellationToken = Nothing) As Task(Of Response)

参数

streamPayload
Stream

包含 Stream 有效负载的 。

partitionKey
PartitionKey

项的分区键。 PartitionKey

requestOptions
ItemRequestOptions

(可选) 项请求的选项 ItemRequestOptions

cancellationToken
CancellationToken

(表示请求取消的可选) CancellationToken

返回

包含 Task 的 , Response 它包装 Stream 包含读取资源记录的 。

示例

将包含该项的流向上插入 Cosmos

using(Response response = await this.container.UpsertItemStreamAsync(stream, new PartitionKey("itemPartitionKey")))
{

    using(Stream stream = response.ContentStream)
    {
        //Read or do other operations with the stream
        using (StreamReader  streamReader = new StreamReader(stream))
        {
            string content =  streamReader.ReadToEndAsync();
        }
    }
}
