Use of Stopwatch Class in C#

Using the following line a new stopwatch object will be created:

System.Diagnostics.Stopwatch myStopWatch = newSystem.Diagnostics.Stopwatch();

The "Start" method will start the stopwatch:

myStopWatch.Start();

The "Stop" method will stop the stopwatch:

myStopWatch.Stop();

To display the value of the stopwatch then use the code shown below:

/// <summary>
/// To get the value of Hours../// </summary>

myStopWatch.Elapsed.Hours.ToString();

/// <summary>
/// To get the value of Minutes../// </summary>

myStopWatch.Elapsed.Minutes.ToString();

/// <summary>
/// To get the value of Seconds..

/// </summary>

myStopWatch.Elapsed.Seconds.ToString();

/// <summary>
/// To get the value of Milliseconds../// </summary>
MyStopWatch.Elapsed.Milliseconds.ToString();

Main Code :

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;using System.Data.SqlClient;

namespace MyBlog{
    public partial class Form1 : Form    {
        public Form1()
        {
            InitializeComponent();
        }
        private void button1_Click(object sender, EventArgs e)
        {
            System.Diagnostics.Stopwatch myStopWatch = newSystem.Diagnostics.Stopwatch();

            //Start StopWatch...            myStopWatch.Start();

            SqlConnection conn = new SqlConnection(@"Data Source=.\SQLEXPRESS;AttachDbFilename=|DataDirectory|\myDatabase.mdf;Integrated Security=True;User Instance=True");
            SqlDataReader dr;
            try            {
                conn.Open();
                SqlCommand cmd = new SqlCommand("SELECT StudName FROM Student WHERE StudId=1", conn);
                dr = cmd.ExecuteReader();
                while (dr.Read())
                {
                    //it will display Name of Student whose Id is "1"...                    mytxtName.Text = dr.GetValue(0).ToString();
                }
                //Stop StopWatch...                myStopWatch.Stop();

                //Display time which taken to load resulted data in textbox in messagebox...                MessageBox.Show("Time Taken : " + myStopWatch.Elapsed.Hours.ToString() + " : " + myStopWatch.Elapsed.Minutes.ToString() + " : " + myStopWatch.Elapsed.Seconds.ToString() + " : " + myStopWatch.Elapsed.Milliseconds.ToString());
                dr.Close();
            }
            catch (Exception ex)
            {
                MessageBox.Show(ex.ToString());
            }
            finally            {
                conn.Close();
            }
        }
    }
}
