I have a simple C# application (.net 4.7.2 windows application)

I/we need to create 3 versions of this application each with its own application icon.

MyApp.exe -> a.ico
MyApp.exe -> b.ico
MyApp.exe -> c.ico

I know how to add the icon for one instance (application properties)

I'm not certain what would be the best approach to have the 3 application each with its own icon.

Thanks for pointing me in the right direction.

What I have tried:

I don't know what to try or what to search for.

Why? I see no benefit of doing that.

Solution 1

Set it at runtime, when you decide "which instance" this run is:

C#

public MyForm()
    {
    InitializeComponent();
    using (FileStream fs = File.OpenRead("App3.ico"))
        {
        Icon = new Icon(fs);
        }
    }

Solution 3

Hello,
Why not add an argument when starting (a, or c) the application and handle the argument in application initialization.

Window icon or application icon?
If you want to switch between different window icons according to different versions, you can add all the icons to the resources of the project.

C#

if(/*add your code*/){
    this.Icon = Properties.Resources.a_ico
}else if(/*add your code*/){
    this.Icon = Properties.Resources.b_ico
}else{
    this.Icon = Properties.Resources.c_ico
}

Solution 2

A simple way would be to use a batch file that replaces the icon and builds the application three times.
You can also load another icon for a form at startup, but this does not change the application icon that you see in explorer.
