返回

一个 TaskResponse ,它包含包装 Stream 包含读取资源记录的 。

示例

以流的形式读取响应。

using(Response response = await this.container.ReadItemStreamAsync("id", new PartitionKey("partitionKey")))
{
    using(Stream stream = response.ContentStream)
    {
        //Read or do other operations with the stream
        using (StreamReader streamReader = new StreamReader(stream))
        {
            string content =  streamReader.ReadToEndAsync();
        }
