本文介绍了一种解决HTTPWebRequest在遇到407错误（代理认证所需）时的方法。通过设置代理对象使用当前登录用户的凭据，并在配置文件中启用默认代理使用默认凭据，可以有效解决此问题。

1. Supply the credentials of the Currently Logged on User to the Proxy object similar to this:

// Begin code change by jeff

 
                    //  Obtain the 'Proxy' of the  Default browser. 
                    IWebProxy theProxy = aReq.Proxy;
                    // Print the Proxy Url to the console.
                    if (theProxy != null)
                    {
// Use the default credentials of the logged on user.
                        theProxy.Credentials = CredentialCache.DefaultCredentials;
                    }
                    // End code change by jeff
 
                    HttpWebResponse aResp = aReq.GetResponse() as HttpWebResponse;

　　2. Add this property to the <<application>>.exe.config or machine.config file:

<system.net>
    <defaultProxy useDefaultCredentials="true"> </defaultProxy>
</system.net>
