Object reference question

[AMP]

Hello,
I have this procedure to convert a Multidimentional string array to an
int but I get an error on line 6
"Object reference not set to an instance of an object".But Ive created
my object on line 1
int i = 0;
1 uint[][] intArray = new uint[Sample.Length][];
2 for (i=0;i<(Sample.Length);i++)
3 {
4 for(int j=0;j<(Sample.Length);j++)
5 {
6 intArray[j]=UInt32.Parse(Sample
[j],System.Globalization.NumberStyles.Integer);

}
}

What am I doing wrong?

This isn't a multidimentional array its an array of arrays of uints.

Just before line 4 you need:-

intArray = new uint[Sample.Length];

First of all, you presumably mean "on line 2".

Real software engineers start counting at zero.
