Replace All char in a string of an object in a list c#

Question

I've got a list of object of this class

public MyClass{
string code;
string other;
string other2;
}

i want to replace all char in code property with a custom char Ex: 'X' ,except last 4 chars, and return the modified list. Possible using linq or not a lot of lines of code?

List<MyClass> classes = new List<MyClass>();
classes = //something that populate the list
classes.Select( e => ???? )
return classes; // returning the modified list

What would you like to replace? Is there any pattern? Please, be more specific and provide more details. — Maciej Los

classes.foreach(c => c.code = new string('X', c.code.Length - 4) + c.code.Substring(c.code.length - 4))

classes = classes
    .Select(c => {
        c.code = new string('X', c.code.Length - 4) + c.code.Substring(c.code.length - 4);
        return c;
    })
    .ToList();
