Question

I’ve come across code in a library that I want to use that I have never seen before (probably because I don’t use c# all that much) and can’t find any documentation on. It doesn’t work in VB.NET and I’m not even sure of what it does so that I could go about doing it some different way. The expression is Mask.NullString(str).Length. Can anyone help me out please?

Answer 1

The implementation of Mask.NullString that I found on the web looks like this:

public static string NullString(string actual) {
    return actual == null ? string.Empty : actual;
}

I’m not an expert in VB, but I think it translates to this:

if(str, String.Empty).Length
