从客户端

Question

我有以下功能：

public string GetADDisplayName(string strLogin)
{
    int length = strLogin.IndexOf('\\');
    if (length == -1)
        length = strLogin.IndexOf('@');
    string str1;
    string str2;
    if (length != -1)
    {
        str1 = strLogin.Substring(0, length);
        str2 = strLogin.Substring(length + 1);
    }
    else
    {
        str1 = Environment.MachineName;
        str2 = strLogin;
    }
    string str3;
    try
    {
        str3 = new DirectoryEntry("WinNT://" + str1 + "/" + str2).Properties["FullName"].Value.ToString();
    }
    catch (Exception ex)
    {
        Page.ClientScript.RegisterStartupScript(Page.GetType(), "", "alert('GetADDisplayName ERROR: " + ex.ToString() + "');", true);
        str3 = "";
    }
    return str3;
}

我传递给函数的值是HttpContext.Current.User.Identity.Name.Trim()。

当我在visual studio中调试/ F5时，它会显示FullName。

当我部署到Web服务器并从Web服务器本身访问它时，它会显示FullName。

但是当我从客户端访问Web服务器时，它未能显示FullName，为什么会这样？

尝试这种方法：

using System;
using System.DirectoryServices;
using System.DirectoryServices.AccountManagement;

using (var principalContext = new PrincipalContext(ContextType.Domain))
{
    using (var userPrincipal = new UserPrincipal(principalContext))
    {
        userPrincipal.SamAccountName = 'userdomain name'; // -> ex. jtabuloc

        using (var principalSearcher = new PrincipalSearcher())
        {
            principalSearcher.QueryFilter = userPrincipal;

            var principal = principalSearcher.FindOne();

            if (principal != null)
            {
                var directoryEntry = (DirectoryEntry)principal.GetUnderlyingObject();

                 // You can examine directoryEntry if key exist and retrieve values                   
                 var Name = directoryEntry["name"][0] as string;
                 var FullName = directoryEntry["FullName"][0] as string;
                 var Email = directoryEntry["mail"][0] as string;
                 var Title = directoryEntry["title"][0] as string;
            }    
        }
    }
}

尝试使用FullName获取AccountManagement：

using System.DirectoryServices.AccountManagement;

UserPrincipal userPrincipal = UserPrincipal.Current;
String name = userPrincipal.DisplayName;
