应用程序更新程序 - 不断收到 401 未经授权的错误
我正在测试 .Net 应用程序更新程序组件，如下所述 更新程序组件
我遇到一个问题，当客户端尝试访问 update.xml 文件时出现 401 Unathorized 访问错误。
当我通过网络浏览器访问该网址时，可以看到 update.xml 文件。有什么想法我做错了吗？
“服务器”部分仅位于本地主机上。

//Retrieve the File
HttpWebRequest Request = (HttpWebRequest)HttpWebRequest.Create(url);
Request.Headers.Add("Translate: f");
Request.Credentials = CredentialCache.DefaultCredentials;
//Set up the last modfied time header
if (File.Exists(filePath))
Request.IfModifiedSince = LastModFromDisk(filePath);
try
{
Response = (HttpWebResponse)Request.GetResponse();// this is where error is being thrown.
}
亲切的问候
阿什
Im testing out the .Net application updater component as decribed here Updater component
Im getting an issue that when the client tries to access the update.xml file I am getting a 401 Unathorized access error.
I can see the update.xml file when I go to the url through the web browser. Any ideas what Im doing wrong?
The "server" part is just on local host.

您是否尝试过通过 fiddler 运行您的 uri？ - http://www.fiddler2.com/fiddler2/
使用此工具，您可以查看请求并响应，并可能找出导致问题的原因，而不仅仅是 401 错误。

您的计算机是否通过身份验证 Web 代理连接到 Internet？如果是，.NET 将不会与代理通信，除非应用程序配置文件包含如下内容：
Is your computer connecting to the Internet via an authenticating web proxy? If it is, .NET won't talk to the proxy unless the application configuration file contains a bit like this:
