Change icon of folder using C#

C#

Hello
Good time
I have more than 1000 movie folders and I want to change the folder icon for any movie based on desktop.ini.
For example, I have a lot of films in the following way.
F:\Movies\
How can I do it in C#.
1. Create a desktop.ini file in each folder.
2. The contents of each desktop.ini file are as follows.

[.ShellClassInfo]
IconResource=*.ico,0

3. In front of the phrase IconResource = Only the file name that has the .ico extension.

for example:

[.ShellClassInfo]
IconResource=Stranger Things.ico,0

please give the idea and source code....

Thank

What I have tried:

The amount of code I've written for a folder. The executable file in the folder creates the desktop.ini file and places it in two lines. And I do not know the rest of the steps. What should I do?

[.ShellClassInfo]
IconResource=

private void button1_Click(object sender, EventArgs e)
        {
            TextWriter tw = new StreamWriter("desktop.ini");
            tw.WriteLine("[.ShellClassInfo]");
            tw.WriteLine("IconResource=" );
            tw.Close();
            
        }
