Question

I need to check that a variable has one of a few different values. Currently I have code lik this:

if (cName == "Products" || cName == "Packages" || cName == "Contents" || cName == "Packages") 
..
if (cName == "Products" || cName == "Packages" || cName == "Contents") 
..
etc

It doesn’t look very clean to me. Is there some simpler one line way I could do this check? Some code where I would not have to keep repeating cName?

You could also have a look at Extension Methods.

public static class StringExtensions
{
    public static bool EqualsAny(this string s, params string[] args)
    {
        return args.Contains(s);
    }

}

Then you could use this ike:

string cName = "Products";

if (cName.EqualsAny("Products", "Packages", "Contents", "Packages"))
{
}
