To declare array size with datatable property

So I'm trying to declare a 2 dimentional array based off the Rows.Count and Columns.Count properties of a datatable. I keep running into the same issue where the array is never initialized therefor as soon as i attempt to assign anything to it, i get out of bounds.

As shown in the code below if I declare the array's with a simple hardcoded int they work just fine, but for some reason it doesn't like the counts. I have separate detection to check those count values and they appear correct as 1(rows) 8(columns) I just apparently can't instantiate with them. Any ideas?

//Tables filled above 
 
string[,] data1 = new string[Convert.ToInt32(tmpTable1.Rows.Count-1),  Convert.ToInt32(tmpTable1.Columns.Count-1)];
 
string[,] data2 = new string[Convert.ToInt32(tmpTable2.Rows.Count-1), Convert.ToInt32(tmpTable2.Columns.Count-1)];
 
MessageBox.Show(Convert.ToString(data1.Length)); //Returns 0
MessageBox.Show(Convert.ToString(data2.Length)); //Returns 0
MessageBox.Show("row#="+y.ToString()+"\rcolumn#="+x.ToString()); //Returns 1 and 8 respectively
 
 
//assignment loops
foreach(DataRow row in tmpTable1.Rows)
{
	x=1;				
	MessageBox.Show("row#="+y.ToString()+"\rcolumn#="+x.ToString()+"\rforeach row in table1");
 
	foreach(DataColumn col in tmpTable1.Columns)
	{
		MessageBox.Show("row#="+Convert.ToString(y-1)+"\rcolumn#="+Convert.ToString(x-1)+"\rforeachcolumn in table1");
 
		//object cellData1 = row[col];
		data1[y-1, x-1] = row[col].ToString(); //Dies here.
		MessageBox.Show(row[col].ToString()); //Returns Correct Info.
		x++;
	}
	y++;
}
