Split and Merge Strings in C# Windows Form Application

Introduction

In this article I explain one of the most important things often used in projects; splitting and merging strings. Splitting a string means making multiple substrings from one single string as determined by a specific separator value. In this article I will split on  a space ( "  ") if a space occurs in the string it will break. And after the string break I display two TextBoxes. I then merge the split strings using the " +" operator and display that single string in another TextBox.

Use the following procedure to implement it.

Step 1

Open a Windows Forms application and insert two buttons and four TextBoxes, each with the multiline property set to true.

Step 2

Now write the C# code for the button click.

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 traslator

{

    public partial class Form1 : Form

    {

        public Form1()

        {

            InitializeComponent();

        }     

        private void button1_Click(object sender, EventArgs e)

        {

            string text = "";

            text = textBox1.Text;

            string[] arr= text .Split (' ');

            textBox2.Text = arr[0];

            textBox3.Text = arr[1];

        }

        private void button2_Click(object sender, EventArgs e)

        {

            textBox4.Text = textBox2.Text + " " + textBox3.Text;

        }     

    }

}

 

 Step 3

Now run your application and enter a string in textbox1 for the split.
