How to Change Icon in Windows Form C#: A Step-by-Step Guide

Changing the icon in a Windows Form using C# involves a few straightforward steps. Here’s how you can do it:

How to Change Icon in Windows Form C#

  1. Prepare Your Icon: Ensure you have the icon file (.ico format) that you want to use. Place this file in an appropriate location within your project’s directory structure.
  2. Add the Icon to Your Project:
    • In Visual Studio, right-click on your project in the Solution Explorer.
    • Choose “Add” > “Existing Item…”.
    • Navigate to the location of your .ico file, select it, and click “Add”.
  3. Set the Icon for the Form:
    • Open the Form’s design view by double-clicking on the Form in the Solution Explorer.
    • In the Properties window (usually found at the bottom right), find the property named “Icon”.
    • Click on the ellipsis (…) button next to the Icon property.
    • This will open a dialog where you can select your icon file from the project resources.
  4. Alternatively, Set the Icon Programmatically:
    • You can also set the icon in the code. In the Form’s constructor (after InitializeComponent();), add the following line of code:
      csharp
      this.Icon = new Icon("path_to_your_icon.ico");
    • Replace "path_to_your_icon.ico" with the relative path to your icon file within the project.
  5. Build and Run Your Application: After setting the icon, build and run your application. The new icon should now appear in the title bar of your form, as well as in the taskbar when the application is running.

Remember, the icon file needs to be included in your project’s output. Ensure it’s set to be copied to the output directory if it’s not in the root of your project. This can be done in the properties window for the icon file in Solution Explorer.
