温习ASP调用C#的DLL并实现用户名密码进行域验证反馈结果

项目示意图：

设置：使程序集COM可见

 设置：为程序集签名

 C#类代码：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.DirectoryServices;
namespace ClassLibrary1
{
    public class Class1
    {
        public string msg;
        public string pat;
        public bool IsAuthenticated(string domain, string username, string pwd)
        {
            string domainAndUsername = domain + @"\" + username;
            pat = "LDAP://" + domain;
            DirectoryEntry entry = new DirectoryEntry(pat, domainAndUsername, pwd);
            try
            {
                //Bind to the native AdsObject to force authentication.
                object obj = entry.NativeObject;
                DirectorySearcher search = new DirectorySearcher(entry);
                search.Filter = "(SAMAccountName=" + username + ")";
                search.PropertiesToLoad.Add("cn");
                SearchResult result = search.FindOne();
                if (null == result)
                {
                    return false;
                }
                //Update the new path to the user in the directory.
                pat = result.Path;
                msg = (string)result.Properties["cn"][0];
            }
            catch (Exception ex)
            {
                msg = ex.Message;
                return false;
            }

            return true;
        }
    }
}

注册DLL：

RegAsm ClassLibrary1.dll /codebase

注销DLL：

RegAsm ClassLibrary1.dll /u

注册组件默认位置：C:\WINDOWS\Microsoft.NET\Framework\v4.0.30319\RegAsm.exe

ASP调用已注册成功的动态链接库

response.Write(isad&","&obj.pat&","&obj.msg)
set obj = nothing
