Syntax question

[Trevor]

I have encountered this line of C# code today:

string[,] m_defaultValues;

What does this syntax "string[,]" mean and how is it different from the
normal "string[]" array syntax ? I don't understand what the comma is
accomplishing.

A two dimensional array.

We can put commas as much as the dimmensions count.
