ReplaceAttachmentAsync(Attachment, RequestOptions, CancellationToken)

将 Attachment Azure Cosmos DB 服务中的 作为异步操作替换。

public System.Threading.Tasks.Task<Microsoft.Azure.Documents.Client.ResourceResponse<Microsoft.Azure.Documents.Attachment>> ReplaceAttachmentAsync (Microsoft.Azure.Documents.Attachment attachment, Microsoft.Azure.Documents.Client.RequestOptions options = default, System.Threading.CancellationToken cancellationToken = default);

abstract member ReplaceAttachmentAsync : Microsoft.Azure.Documents.Attachment * Microsoft.Azure.Documents.Client.RequestOptions * System.Threading.CancellationToken -> System.Threading.Tasks.Task<Microsoft.Azure.Documents.Client.ResourceResponse<Microsoft.Azure.Documents.Attachment>>
override this.ReplaceAttachmentAsync : Microsoft.Azure.Documents.Attachment * Microsoft.Azure.Documents.Client.RequestOptions * System.Threading.CancellationToken -> System.Threading.Tasks.Task<Microsoft.Azure.Documents.Client.ResourceResponse<Microsoft.Azure.Documents.Attachment>>

Public Function ReplaceAttachmentAsync (attachment As Attachment, Optional options As RequestOptions = Nothing, Optional cancellationToken As CancellationToken = Nothing) As Task(Of ResourceResponse(Of Attachment))

参数

attachment

Attachment

已更新 Attachment ，以将现有资源替换为 。

options

RequestOptions

(可选) 请求的请求选项。

cancellationToken

CancellationToken

(可选) A CancellationToken ，其他对象或线程可以使用它来接收取消通知。

返回

Task<ResourceResponse<Attachment>>

包含 System.Threading.Tasks 的 ， ResourceResponse<TResource> 它包装 Attachment 包含已更新资源记录的 。

实现

ReplaceAttachmentAsync(Attachment, RequestOptions, CancellationToken)

例外

ArgumentNullException

如果未 attachment 设置 。

DocumentClientException

此异常可以封装许多不同类型的错误。 若要确定特定错误，请始终查看 StatusCode 属性。 创建文档时可能会获取的一些常见代码包括：

StatusCode	异常原因

示例

//Fetch the item to be updated
Attachment attachment = client.CreateAttachmentQuery(attachmentLink)
                            .Where(r => r.Id == "attachment id")
                            .AsEnumerable()
                            .SingleOrDefault();

//Update some properties on the found resource
attachment.MediaLink = "updated value";

//Now persist these changes to the database by replacing the original resource
Attachment updated = await client.ReplaceAttachmentAsync(attachment);
