Using Progress Bar In C#

Using Progress Bar in C#:

Progress Bar is very commonly used control in many applications to display the progress of task being performed. Progress Bar is displayed when copying files, deleting files or installing some software.

How to use Progress Bar:

·         Start New Windows Form Application.

·         Go to Toolbox.

·         Select Progress Bar and Drag it to your Form.

To make Progress Bar working you need to know some properties of Progress Bar

Progress Bar.Maximum: Defines how long it should run

Progress Bar.Step: Defines how much it should increase current position of Progress Bar.

Progress Bar.Style: How should it look like?

There is also a very basic method which is used to run Progress Bar properly.

Progress Bar.PerformStep()

Let’s see an example. In this example we will copy files and folders from one location to another and show the progress bar while copying.

namespace copynestedfolderformapplication

{

    public partial class Form1 : Form

    {

         int maxbytes = 0;

         int copied = 0;

         int total=0;

       

        public Form1()

        {

            InitializeComponent();

        }

        private void copybtn_Click(object sender, EventArgs e)

        {

            Copy1(@"F:\Posts", @"G:\copydata");

          

            MessageBox.Show("Done");

        }

       

        public void Copy1(string sourceDirectory, string targetDirectory)

        {

         

            DirectoryInfo diSource = new DirectoryInfo(sourceDirectory);

            DirectoryInfo diTarget = new DirectoryInfo(targetDirectory);

          //Gets size of all files present in source folder.

            GetSize(diSource, diTarget);

            maxbytes = maxbytes / 1024;

           

            progressBar1.Maximum = maxbytes;

            CopyAll(diSource, diTarget);

        }

        public void CopyAll(DirectoryInfo source, DirectoryInfo target)

        {

           

            if (Directory.Exists(target.FullName) == false)

            {

                Directory.CreateDirectory(target.FullName);

            }

            foreach (FileInfo fi in source.GetFiles())

            {

               

                fi.CopyTo(Path.Combine(target.ToString(), fi.Name), true);

                total += (int)fi.Length;

               

                copied += (int)fi.Length;

                copied /= 1024;

                progressBar1.Step =copied;

                            

                progressBar1.PerformStep();

                label1.Text = (total/1048576).ToString() + "MB of " + (maxbytes/1024).ToString() + "MB copied";

               

               

              

                label1.Refresh();

            }

            foreach (DirectoryInfo diSourceSubDir in source.GetDirectories())

            {

               

              

              

                DirectoryInfo nextTargetSubDir = target.CreateSubdirectory(diSourceSubDir.Name);

                CopyAll(diSourceSubDir, nextTargetSubDir);

            }

        }

        public  void GetSize(DirectoryInfo source, DirectoryInfo target)

        {

        

            if (Directory.Exists(target.FullName) == false)

            {

                Directory.CreateDirectory(target.FullName);

            }

            foreach (FileInfo fi in source.GetFiles())

            {

                maxbytes += (int)fi.Length;//Size of File

             

              

            }

            foreach (DirectoryInfo diSourceSubDir in source.GetDirectories())

            {

                DirectoryInfo nextTargetSubDir = target.CreateSubdirectory(diSourceSubDir.Name);

                GetSize(diSourceSubDir, nextTargetSubDir);

             

            }

           

        }

    }

}

It will display a Form like this after copying the files.
