此博客展示了一段C#代码，用于在代理需要认证模式时，提供用户名、密码和域名进行网页请求。代码通过创建HttpWebRequest对象，设置网络凭证和缓存，获取网页响应并读取内容，最后将结果显示在页面上。

// Source Code starts
<%@ Import Namespace="System.Net" %>
<%@ Import Namespace="System.IO" %>
<script language="C#" runat="server">
void Page_Load(Object Src, EventArgs E) {
myPage.Text = readHtmlPage("http://www.c-sharpcorner.com");
}

private String readHtmlPage(string url)
{
String result;
WebResponse objResponse;
WebProxy proxyObject = new WebProxy("http://urproxy:port/",true);
WebRequest objRequest = System.Net.HttpWebRequest.Create(url);
objRequest.Proxy = proxyObject;

objResponse = objRequest.GetResponse();
using (StreamReader sr =
new StreamReader(objResponse.GetResponseStream()) )
{
result = sr.ReadToEnd();
// Close and clean up the StreamReader
sr.Close();
}
return result;
}
</script>
<html>
<body>

<b>This content is being populated from a separate HTTP request to
<a href="http://www.c-sharpcorner.com">www.c-sharpcorner.com</a></b><hr/>
<asp:literal id="myPage" runat="server"/>
</body>
</html>

// Source Code End

//While Here is the Code where you need to Provide UserName,Password and //domainName if your Proxy requires these Authentication Mode.

<%@ Import Namespace="System.Net" %>
<%@ Import Namespace="System.IO" %>
<script language="C#" runat="server">
void Page_Load(Object Src, EventArgs E) {
myPage.Text = readHtmlPage("http://www.c-sharpcorner.com");
}

private String readHtmlPage(string url)
{
String result;
HttpWebRequest makeReq =(HttpWebRequest)WebRequest.Create("http://www.shivanicreations.com/");
NetworkCredential giveCred = new NetworkCredential("username","password","domain");
CredentialCache putCache = new CredentialCache();
putCache.Add(new Uri("http://www.shivanicreations.com/"), "Basic", myCred);
makeReq.Credentials = myCache;
WebResponse objResponse;
objResponse = objRequest.GetResponse();
using (StreamReader sr = new StreamReader(objResponse.GetResponseStream()) )
{
result = sr.ReadToEnd();
// Close and clean up the StreamReader
sr.Close();
}
return result;
}
