Array of Arrays

Question

How do you create an array of arrays in C#? I have read about creating jagged arrays but I'm not sure if thats the best way of going about it. I was wanting to achieve something like this:

string[] myArray = {string[] myArray2, string[] myArray3}

Then I can access it like myArray.myArray2[0];

I know that code won't work but just as an example to explain what I mean.

Thanks.
