Question

I have c# strings looking like this:

"abc";
"def.";

When I read these into another variable I need some simple way to check the last character of the string and if it’s not a period then append a period to that string.

Does anyone have any ideas of a simple way I could do this?

namespace ExtensionMethods
{
    public static class StringExtensionMethods
    {
        public static string EnsureEndsWithDot(this string str)
        {
            if (!str.EndsWith(".")) return str + ".";
            return str;
        }
    }
}
