第1步：

创建新项目并创建新的Web服务。

第2步：

写下面的方法：

Hello Christian,

Thank you very much for your reply.

I've solved the issue myself.

I am posting the code below, which may help others:

Step 1:
Create new project and Create New Webservice.
Step 2:
Write the following method:

[WebMethod(Description = "Validate a username and password against Active Directory")]
       public bool Authentication(string domain, string username, string password)
       {
           var val = true;
           try
           {
               DirectoryEntry entry = new DirectoryEntry("LDAP://" + domain, username, password);
               DirectorySearcher search = new DirectorySearcher(entry);

               search.Filter = "(SAMAccountName=" + username + ")";
               var uname = search.PropertiesToLoad.Add("cn");

               SearchResult result = search.FindOne();
               if (result == null)
               {
                   val = false;
               }
           }
           catch
           {
               val = false;
           }
           return val;
       }

第3步：

在你的项目中使用这个web服务。

Step 3:
Consume this web service in your project.

private void Register_Click(object sender, RoutedEventArgs e)
        {
            try
            {
                //User Name can not be blank
                if (txtUsername.Text.Trim() == "")
                {
                    lblStatus.Text = "Please Enter Username";
                }
                
                //Password can not be blank
                else if (txtPassword.Password == "")
                {
                    lblStatus.Text = "Please Enter Password";
                }

                else
                {
                    //Creating object for "your created web service name (I am taking my web service as Domain_Auth" web service for Authentication
// I am taking WS as proxy name here and 


                    WS.Domain_AuthSoapClient client = new WS.Domain_AuthSoapClient();
                    client.AuthenticationCompleted += new EventHandler<authenticationcompletedeventargs>(Client_AuthenticationCompleted);
                    client.AuthenticationAsync(" your domain name", txtUsername.Text, txtPassword.Password);
                }
            }
            catch (Exception ex)
            {
                MessageBox.Show(ex.Message);
            }
        }

        //Event Handler for Authentication Method
        void Client_AuthenticationCompleted(object sender, AuthenticationCompletedEventArgs e)
        {

            if (e.Error != null)
            {
                lblStatus.Text = "Sorry, an error occured. " + e.Error.Message;
            }

            if (e.Result == true)
            {
                //Do something
            }
            else
            {
                //Do something
            }
        }


</authenticationcompletedeventargs>

谢谢非常感谢。
