Palindrome test function

[Lone-Wolf]

I just started nightschool to learn c# (learn programming at all)

We got an exercise where we need to test for a palindrome

We were asked to put the test in a function and then call the result in a messagebox.

I'm kinda stuck on the last part the calling.
Here's what I have so far:

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;

namespace Pallindroom_testen
{
    public partial class frmPallindroom : Form
    {

        string strWoord1 = "";


        public frmPallindroom()
        {
            InitializeComponent();
        }

        private void btnExit_Click(object sender, EventArgs e)
        {
            this.Close();
        }
        private string controle(string sControle)
        {
            strWoord1 = txtWoord.Text;
            int iTeller = strWoord1.Length;
            string strWoord2 = "";
            string strControle = "";

            for (int iI = 1; iI < iTeller + 1; iI++)
            {
                strWoord2 += strWoord1.Substring(iTeller - iI, 1);
            }
            if (strWoord2.Equals(strWoord1))

                strControle = "Het woord " + strWoord1 + " is een pallindroom";

            else

                strControle = "Het woord " + strWoord1 + " is geen pallindroom";


            return strControle;
        }

        private void btnTest_Click(object sender, EventArgs e)
        {
            MessageBox.Show(controle(sControle).ToString);
        }
    }
}

Any ideas?

I solved it myself :)

string message = controle(strWoord1);
MessageBox.Show(message);
