ASP.NET 取得用戶端資訊

using System.Collections.Specialized  

int loop1, loop2;
   NameValueCollection coll;
 
   // Load ServerVariable collection into NameValueCollection object.
   coll=Request.ServerVariables;
   // Get names of all keys into a string array.
   String[] arr1 = coll.AllKeys;
   for (loop1 = 0; loop1 < arr1.Length; loop1++)
   {
    Response.Write("Key: " + arr1[loop1] + "<br>");
    String[] arr2=coll.GetValues(arr1[loop1]);
    for (loop2 = 0; loop2 < arr2.Length; loop2++)
    {
     Response.Write("Value " + loop2 + ": " + arr2[loop2] + "<br>");
    }
   }

 

 

====以下是一個取得IP和作業系統以及瀏覽器的例子=========

private string getIp()
{/*穿過Proxy 伺服器取遠端使用者真實IP地址：*/
if(Request.ServerVariables["HTTP_VIA"]!=null)
return Request.ServerVariables["HTTP_X_FORWARDED_FOR"].ToString();
else
return Request.ServerVariables["REMOTE_ADDR"].ToString();
}
Label2.Text =getIp();
HttPBrowserCapabilities bc = new HttpBrowserCapabilities();
bc = Request.Browser;
string xitong ="你的作業系統為";
Label3.Text=xitong+bc.Platform + " 瀏覽器類型:" + bc.Type;
