Is there a simpler way to do this if statement in C#

Question

I have the following:

if (model.PartitionKey.Substring(2, 2) == \"05\" || 
    model.PartitionKey.Substring(2, 2) == \"06\")

I have more like t

Answer 1

You can save the substring in a variable:

var substring = model.PartitionKey.Substring(2, 2);
if (substring == "05" || substring == "06")

Or you could use a regular expression:

if (Regex.IsMatch("^..0[56]", model.PartitionKey))

This probably depends a bit on how easily you can understand a regex while reading code.
