c# - 为什么我不能在 C# 代码文件中使用 Request.ServerVariables ["ALL_HTTP"]？

Question

我可以使用Request.ServerVariables["ALL_HTTP"]在 .Aspx 文件中 % 标记之间， 即<%=Request.ServerVariables["ALL_HTTP"]%> 但 .cs 文件将无法识别 namespace 。是什么赋予了？我需要将这些变量放入代码文件中的数组中。

public partial class _Default : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {

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


    }
