В этой статье Вы узнаете, как поменять иконку в форме Windows Forms в Visual Studio. Это очень легко!
При создании проекта форма со стандартной иконкой выглядит так:
Нам хочется внести оригинальность в оформление нашей программы, и стандартная иконка нам не нужна. Но где же поменять её?
Для этого мы заходим в «Свойства». Они практически всегда находятся в правой части Visual Studio и обозначаются небольшой иконкой :
Если по каким-либо причинам Вы не нашли «Свойства», то просто кликните правой кнопкой мыши на форме и там выберите этот пункт.
С этим разобрались. Теперь ищем строку с названием Icon. Именно она нам и нужна:
Видим справа тот самый значок, что всегда висит у нас в форме.
Нажимаем на кнопку с многоточием — она откроет нам обозреватель файлов. И, казалось бы, осталось выбрать любую картинку и всё готово, но это не так.
Visual Studio примет в этом параметре только те изображения, которые соответствуют формату .ico (специальный формат для иконок). однако в сети существует множество программ и сайтов, которые без труда переведут любое изображение в формат .ico.
Также существует огромное количество паков и просто отдельных изображений этих форматов. Допустим, мы создали или выбрали наше изображение в нужном формате. Теперь нам остаётся лишь загрузить его.
У нас для примера будет вот такое изображение формата .ico:
Мы выбираем его в обозревателе файлов и нажимаем «Открыть».
Значок в свойствах сменился.
Смотрим на нашу форму:
Всё работает!

If you are creating a new desktop application, you may be following your own branding and design. This might include a custom color palette, UI design, or the icon that displays when a user opens your app.
When using Windows Forms to create your app, Visual Studio adds a default icon in the top-left corner of your application’s window. You can change this to an icon of your choice by modifying the form’s properties.
How to Change the Application’s Icon
You can change the default icon by accessing the form’s properties and uploading a new icon image.
- Create a new Windows Forms application or open up an existing one.
-
By default, the designer view should be open. If not, right-click on the Form in the Solution Explorer window and click on View Designer.
-
The designer view acts as a canvas that you can use to add and modify UI elements. It also reflects what your application will look like at runtime. The current icon for your application shows in the top-left corner of the form. If you do not have an icon, Visual Studio will use a default icon.
-
Highlight the form by selecting it, and navigate to the Properties pane. This is usually located in the lower right-hand corner of the Visual Studio window.
- Click on the three dots (…) next to the Icon field.
- In the new file explorer window pop-up, select your new icon. Upload a photo that uses an icon format such as an .ico file. If you are having trouble finding or creating icons, you can create a custom icon using Rainmeter.
-
In the file explorer window, click on open to save the file. This will update the canvas with the new icon.
How to Run the Application and View Your Icon
You can view what your new icon looks like at runtime by launching the application.
-
Click on the green play button at the top of the Visual Studio window.
-
Wait for the application to compile. Once completed, the application window will launch showing the new icon in the top-left corner.
Creating Desktop Applications Using Windows Forms
If you are developing an application using Windows Forms, there is a chance you may want to change the icon to match your design.
You can change the icon in Visual Studio by opening the properties window for the form. You can then upload a new icon image to the icon field.
You may also want to add other UI elements or images to your app. If so, you can learn more about how to add graphics to a Windows Form application.
Introduction
It was difficult to create an icon with the bitmap editor that comes with Visual Studio, so I tried to summarize how to create an icon using Microsoft Paint.
Note 1
You cannot edit 32-bit icons and PNGs with the image editor provided as standard in visual studio. A separate paint tool is required.
Note 2
The file format of ico files is different from that of bmp that can be displayed using the windows system compatibility function. Use an app such as @icon Converter to convert to ICO file format.
If the format is not changed correctly, a warning will be displayed when adding an icon.
File formats that can be used for icons
| size | Number of colors | file format |
|---|---|---|
| 256 x 256 | 32bit | PNG |
| 48 x 48 | 8bit | BMP |
| 32 x 32 | 8bit | BMP |
| 16 x 16 | 8bit | BMP |
| 256 x 256 | 32bit | PNG |
| 64 x 64 | 32bit | BMP |
| 48 x 48 | 32bit | BMP |
| 32 x 32 | 32bit | BMP |
| 16 x 16 | 32bit | BMP |
Icon registration procedure
-
Create a bmp file with a paint tool such as mspaint. Format conversion with @icon etc.
-
Create (or open) the project to which you want to add an icon in visual studio.
-
Open the project properties.
-
Click the [Browse] button on the icon.
-
Select the ico file from Windows Explorer.
-
Confirm that the icon is loaded.
-
When you build the project (or build with debugging), you can see that ico is embedded in the executable file.
