Hi there. I am a newbie in C# and here are 2 questions:

1. I have a 2d array a[3,3], how can I express one dimension as a new array and pass to some function.

i.e.

int[,] a = new int[3,3];

a[0,0] = 1;

...

string b = concatenate(a[0]); // where concatenate is a function take a one dimension array as param

1. Can I create a 65000x65000 array with C#? I got some "out of memory" error.

Thanks in advance.
