Well, can you do it?

Have you tried? Did it work?

The first code block is using pattern matching, it's a specific feature where you can use or to test against for different matches. The second code block uses the binary conditional logic operators which only work on booleans (true or false).

Only works with bools and it so happens the logical and equality operators return bool. Pattern matching helps make it more readable and can warn you if the expression is contradictory or will always be true. As a side effect, pattern matching only works when comparing to constants.

The code you've shown compiles into plain ||'s. Take a look at sharplab decompile:

internal class Program
{
    private static void <Main>$(string[] args)
    {
        string text = "any";
        if (text == "item1" || text == "item2" || text == "any")
        {
            Console.WriteLine("okay");
        }
    }
}

Thanks for best explain.
