I am getting red underline under "if (IsAuthenticated)". How can i fix it?

Below is the full code.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Net;
using System.DirectoryServices;

namespace WebApplication1
{
    public partial class _Default : System.Web.UI.Page
    {
        protected void btnLogin_Click(object sender, EventArgs e)
        {
            string DomainName = "ldap://11.12.202.38:389";
            IsAuthenticated(DomainName, TextBox1.Text, TextBox2.Text);
           
            if (IsAuthenticated)
            {
                lblResult.Text = "login Success";
            }
            else
            {
                lblResult.Text = "login failed";
            }
        }
        public bool IsAuthenticated(String domain, String username, String pwd)
        {
            //Create the directory entry
            // Give LDAP Server IP along with OU
            // e.g : LDAP://29.29.29.29:389/DC=YourDomain,DC=com"
            string _path = "LDAP://11.12.202.38:389";
            string _filterAttribute = "";
            String domainAndUsername = domain + @"\" + username;
            DirectoryEntry entry = new DirectoryEntry(_path, domainAndUsername, pwd);
            bool returnval = true;
            string ErrDesc = "";

            try
            {
                //Bind to the native AdsObject to force authentication.
                Object obj = entry.NativeObject;
                //Search the user on the Active Directory
                DirectorySearcher search = new DirectorySearcher(entry);
                search.Filter = "(SAMAccountName=" + username + ")";
                search.PropertiesToLoad.Add("cn");
                SearchResult result = search.FindOne();
                if (null == result)
                {
                    returnval = false;
                }

                //Update the new path to the user in the directory.
                _path = result.Path;
                _filterAttribute = (String)result.Properties["cn"][0];
            }
            catch (Exception ex)
            {
                returnval = false;
                ErrDesc = "Error authenticating user. " + ex.Message;
            }

            return returnval;
        }

    }
}

What is isauthenticated supposed to be? I don't see a property or variable witht the same name. I see an isauthenticated method.

I would try changing this line: bool IsAuthenticated = IsAuthenticated(DomainName, TextBox1.Text, TextBox2.Text);

I changed the

public bool IsAuthenticated(String domain, String username, String pwd)

TO

public bool IsAuthenticated(DomainName, TextBox1.Text, TextBox2.Text)

Right next commas, there is red line displaying "Identifer expected"

I should have been more clear. The change I suggested is to the second line in the button click handler of the code you posted above.

I changed the

IsAuthenticated(DomainName, TextBox1.Text, TextBox2.Text);

TO

bool IsAuthenticated = IsAuthenticated(DomainName, TextBox1.Text, TextBox2.Text);

"IsAuthenticated" has red line,here is message for red line "(Local Variable) bool IsAuthenticated Error: 'IsAuthenticated' is a 'variable' but used like a 'method'
