Find Mid Character

Try the following.

In the case of input of even length(e.g. abcd), the mid character is taken as the first of the two middle characters (i.e. b):

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 Middle_chracter
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }
        public static string Result;

       
        public static string Midstring(string inputString)
        {

            int length = inputString.Length;

            Double midvalue = length / 2;

            if (length % 2 != 0)
            {

                int mid = Convert.ToInt32(midvalue);

                char[] InputString = inputString.ToCharArray();

                Result = InputString[mid].ToString();

            }

            else
            {

                Result = "Sorry, we can't give the Result";

            }

            return Result;

        }

        private void btn_middle_char_Click(object sender, EventArgs e)
        {
            //string Result = Midstring(textBox1.Text);
            string Result = Midstring("Apple");
            MessageBox.Show("Result:" + " " + Result.ToUpper() + " " + " is middle character in the given string");
        }

    }
}
