Question

My mind has gone completely blank as to how to validate a null text value

All I need to do is check if an entered value is blank, if so ask again without continuing.

Console.WriteLine("Venue Name - ");
String venName = Console.ReadLine();

I can think how to do it with various loops and IF statements, but I’m sure there’s a far more efficient way, please help.

Not sure how or why you would do it without a loop or an if statement. Try this:

String venName = null;
while (String.IsNullOrEmpty(venName)) {
    Console.WriteLine("Venue Name - ");
    venName = Console.ReadLine();
}
