Inputbox C#

Many vb/vb.net developers are used with the InpuBox(it displays a prompt and waits for the user to input text then returns a string containing the contents of the text box)..... 
In using C# InputBox is not available!!!! so i decided to create one. 
So i might help someone who needs this kind of functionality!

clsInputBox.cs

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

namespace InputBoxCS
{
    public class clsInputBox
    {
        private static Form frmInputBox = new Form();
        private static Label lblPrompt = new Label();
        private static Button btnOk = new Button();
        private static Button btnCancel = new Button();
        private static TextBox txtResponse = new TextBox();
        

        /// 

        /// Initialize the controls
        /// 
        static clsInputBox()
        {
      
            frmInputBox.StartPosition = FormStartPosition.CenterScreen;
            frmInputBox.MinimizeBox = false;
            frmInputBox.MaximizeBox = false;
            frmInputBox.FormBorderStyle = FormBorderStyle.FixedDialog;

            frmInputBox.Controls.AddRange(new Control[] { lblPrompt , btnOk , btnCancel, txtResponse});
            frmInputBox.Size = new Size(346, 130);
            frmInputBox.AcceptButton = btnOk;
            frmInputBox.CancelButton = btnCancel;


            btnOk.Size = new Size(50, 23);
            btnOk.Location = new Point(278, 4);

            btnCancel.Size = new Size(50, 23);
            btnCancel.Location = new Point(278, 33);

            lblPrompt.AutoSize = true;
            lblPrompt.Location = new Point(12, 14);

            txtResponse.Size = new Size(316, 20);
            txtResponse.Location = new Point(12, 62);
        }

        public static DialogResult Show (string Prompt, string title, string defaultresponse, ref string value )
        {
            frmInputBox.Text = title;
            lblPrompt.Text = Prompt;
            btnOk.Text = "&OK";
            btnCancel.Text = "&Cancel";
            btnOk.DialogResult = DialogResult.OK;
            btnCancel.DialogResult = DialogResult.Cancel;

            txtResponse.Focus();

            DialogResult result = frmInputBox.ShowDialog();
            value = txtResponse.Text;

            return result;

        }
    }
}

Form1.cs

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 InputBoxCS
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void button3_Click(object sender, EventArgs e)
        {
            string value  = "";

            if (DialogResult.OK == InputBoxCS.clsInputBox.Show("this my prompt", "this is my title", "response", ref value))
            {
                MessageBox.Show(value);
            }
        }
    }
}
