Question

我是C＃的新手，我遇到了一个我无法调用以显示在我的aspx页面上的变量的问题。

背后的代码如下：

using System;
using System.Collections;
using System.Configuration;
using System.Data;
using System.Linq;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.HtmlControls;
using System.Xml.Linq;
using System.DirectoryServices;
using System.DirectoryServices.AccountManagement;

namespace PRIIS
{
   public partial class _Default : System.Web.UI.Page
   {
    private DirectoryEntry GetDirectoryObject()
    {
        DirectoryEntry oDE;
        oDE = new DirectoryEntry("LDAP://192.168.5.4", "user", "xxxx", AuthenticationTypes.Secure);
        return oDE;
    }
    public DirectoryEntry GetUser(string UserName)
    {
        DirectoryEntry de = GetDirectoryObject();
        DirectorySearcher deSearch = new DirectorySearcher();
        deSearch.SearchRoot = de;

        deSearch.Filter = "(&(objectClass=user)(SAMAccountName=" + UserName + "))";
        deSearch.SearchScope = SearchScope.Subtree;
        SearchResult results = deSearch.FindOne();

        if (!(results == null))
        {
            de = new DirectoryEntry(results.Path, "user", "xxxx", AuthenticationTypes.Secure);
            return de;
        }
        else
        {
            return null;
        }

    }
    public class MyUserName
    {
        public string strName;
        public string str;

        public void userNameOnSystem()
        {
            strName = HttpContext.Current.User.Identity.Name.ToString();
            string[] splitString = strName.Split('\\');
            str = splitString[1];
        }



    }

    protected void Page_Load(object sender, EventArgs e)
    {

        DirectoryEntry de = GetUser("dramirez");
        if (de != null)
        {

            string displayUser = de.Properties["displayName"].Value.ToString();

            Response.Write(displayUser + "<br/>");
            //Response.Write(de.Properties["telephoneNumber"].Value.ToString() + "<br/>");
            //Response.Write(de.Properties["mail"].Value.ToString() + "<br/>");
            //Response.Write(de.Properties["userPrincipalName"].Value.ToString() + "<br/>");

           } 



       }

   }

}

我正在进行的调用是使用以下语句在.aspx页面上显示的displayUser字符串

<%= displayUser %>

不幸的是我收到了错误;

错误2当前上下文中不存在名称“displayUser”

我不确定问题的来源和来源。

提前感谢您的帮助。

Answer 1

为了以这种方式从ASPX标记中访问值，它应该是代码隐藏中的属性（至少protected访问，我相信）。像这样：

protected string DisplayUser { get; set; }

protected void Page_Load(object sender, EventArgs e)
{
    DirectoryEntry de = GetUser("dramirez");
    if (de != null)
    {
        DisplayUser = de.Properties["displayName"].Value.ToString();
    } 
}

然后它应该显示：

<%= DisplayUser %>

Answer 2

将您的变量声明为Public。

 public string displayUser;
 protected void Page_Load(object sender, EventArgs e)
    {

        DirectoryEntry de = GetUser("dramirez");
        if (de != null)
        {

            displayUser = de.Properties["displayName"].Value.ToString();

            Response.Write(displayUser + "<br/>");
            //Response.Write(de.Properties["telephoneNumber"].Value.ToString() + "<br/>");
            //Response.Write(de.Properties["mail"].Value.ToString() + "<br/>");
            //Response.Write(de.Properties["userPrincipalName"].Value.ToString() + "<br/>");

           } 



       }

无法将我的代码后面的变量传递给.net页面
