We'll develop an application in which we'll get all images from a directory and add those images in a ListView. Open visual studio and create new " Windows Form Application " project. Go to Toolbox and drag and drop a ListView. Change name of that ListView to " imageListView ". Double at form and it'll navigate you to its load event. Now add following code in form load event. private void Form1_Load(object sender, EventArgs e) {     ImageList imageList = new ImageList();     // Clear imageList and imageListView     this.imageListView.Items.Clear();                 // Get directory info     DirectoryInfo dir = new DirectoryInfo(@"D:\Images");     // Read all files in directory     foreach (FileInfo file in dir.GetFiles())     {         try         {             imageList.Images.Add(Image.FromFile(file.FullName));         }         catch         {             Console.WriteLine("This is not an image file");

We'll develop an application in which user can select multiple images by " OpenFileDialog " and copy those images to specific directory after resizing it. Open visual studio and create new " Windows Form Application " project. Go to Toolbox and drag a button. Change name of button to " FileUploadBtn ". Change text of button to " Upload & Resize Images ". Now double click at that button and add following code in its click event private void FileUploadBtn_Click(object sender, EventArgs e) {     OpenFileDialog openFileDialog = new OpenFileDialog();     //Add filter, if you want to allow all extenssions just remove it.     openFileDialog.Filter = "Images (*.BMP;*.JPG;*.GIF)|*.BMP;*.JPG;*.GIF|" + "All files (*.*)|*.*";     // Set multiselect true for slecting multiple files     openFileDialog.Multiselect = true;                // Show open file dialog and check if Open button is pressed.     if (openFil

We are going to create an application in which we'll add button in its click event programmatically. You just have to create a new object of " Button " format it (location, name, text, size etc), assign a click event, add it to the form and declare and initialize that click event. Open visual studio and create new " Windows Form Application " project. Double click at form and you will be in that form's " Form1_Load " event code. Now add following code in you  private void Form1_Load(object sender, EventArgs e) {       Button MyBtn = new Button();       // Button formation and other setting       MyBtn.Location = new System.Drawing.Point(100, 100);       MyBtn.Name = "MyButton";       MyBtn.Size = new System.Drawing.Size(75, 23);       MyBtn.TabIndex = 0;       MyBtn.Text = "My Button";       MyBtn.UseVisualStyleBackColor = true;       // Set button click event       MyBtn.Click += new EventHandler(Button_C
