WebClient.UploadValuesCompleted 事件

命名空间:

System.Net

程序集:

System.Net.WebClient.dll

Source:

WebClient.cs

当名称/值集合的异步上传完成时发生。

public:
 event System::Net::UploadValuesCompletedEventHandler ^ UploadValuesCompleted;

Public Custom Event UploadValuesCompleted As UploadValuesCompletedEventHandler

UploadValuesCompletedEventHandler

注解

谨慎

WebRequest、HttpWebRequest、ServicePoint和 WebClient 已过时，不应将其用于新开发。 请改用 HttpClient。

每次异步上传 NameValueCollection 对象的数据完成时都会引发此事件。 这些上传是通过调用 UploadValuesAsync 方法启动的。

UploadValuesCompletedEventHandler 是此事件的委托。 UploadValuesCompletedEventArgs 类为事件处理程序提供事件数据。
