How to resize multidimensional (2D) array in C#?

I have 2D array : myarray[5,6];
And my array is already full. But still, i want to add some more elements in it.
So , how to extend the size of an array?
OR
how to declare dynamic 2D array? (Sorry for asking silly question :P)

Answer 1

What you want is a List of Lists.

List<List<int>> data = new List<List<int>>();

for(int i = 0; i < rowsToAdd; i++)
{
   List<int> newRow = new List<int>();
   for(int j = 0; j < columnsToAdd; j++)
   {
       newRow.Add(j);
   }
   data.Add(newRow);
}

Then to add a new row:

List<int> nextRow = new List<int>(){0,1,2,3};
data.Add(nextRow);
