C# version of the Python code

I have seen this type of problem on many Python test sites and books.  I created this code in both C# and Python sections to show the difference in coding.

def print_alpha_numeric(abc_list, number_list):
   for char in abc_list:
      for num in number_list:
         print(char, num)

print_alpha_numeric(['a', 'b', 'c'], [1, 2, 3])

a 1
a 2
a 3
b 1
b 2
b 3
c 1
c 2
c 3
