/win32icon (C# Compiler Options)

  • Article

The /win32icon option inserts an .ico file in the output file, which gives the output file the desired appearance in the File Explorer.

/win32icon:filename

Arguments

  • filename
    The .ico file that you want to add to your output file.

Remarks

An .ico file can be created with the Resource Compiler. The Resource Compiler is invoked when you compile a Visual C++ program; an .ico file is created from the .rc file.

See /linkresource (to reference) or /resource (to attach) a .NET Framework resource file. See /win32res to import a .res file.

To set this compiler option in the Visual Studio development environment

  1. Open the project's Properties pages.

  2. Click the Application property page.

  3. Modify the Application icon property.

For information on how to set this compiler option programmatically, see ApplicationIcon.

Example

Compile in.cs and attach an .ico file rf.ico to produce in.exe:

csc /win32icon:rf.ico in.cs
