Code Wars C# 6 kyu: Split Strings

Beginner level C# object oriented programming series. Viewers are provided a string as input. They must return an array of strings containing pairs of characters from the input. If the input length is odd, meaning the last character cannot be paired with anything, add an underscore character to make the final pair.
