Here's the code to create Auto Complete Brackets for RichTextBox using C#.

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

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

        //declare  isCurslyBracesKeyPressed variable as Boolean and assign false value  
        //to check { key is pressed or not  
        public static Boolean isCurslyBracesKeyPressed = false;  

        //richTextBox1 KeyPress events  

        // if key (,{,<,",',[ is pressed then insert opposite key to richTextBox1 at Position SelectionStart+1  
        // add one line after inserting, e.Handled=true;  
        //finally set SelectionStart to specified position  

        private void richTextBox1_KeyPress(object sender, KeyPressEventArgs e)  
        {  
            String s = e.KeyChar.ToString();  
            int sel = richTextBox1.SelectionStart;  
            if (checkBox1.Checked == true)  
            {  
                switch (s)  
                {  
                    case "(": richTextBox1.Text = richTextBox1.Text.Insert(sel, "()");  
                        e.Handled = true;  
                        richTextBox1.SelectionStart = sel + 1;  
                        break;
