Subscripted array not compiling

[aewarnick]

Error: Highlights the j loop and says, "Object reference not set to an instance of an object."

 

Help.

 

int[][]x = new int[6][];

x[0]=new int[] {1,2};

x[1]=new int[] {3,4,5};

x[2]=new int[] {6,7};

 

for (int i=0; i<x.Length; ++i)

for (int j=0; j<x.Length; ++j)

{

RTB1.Text+=" "+x.Length;

TB2.Text+=" "+x.Length;

TB1.Text+=x[j];

RTB2.Text+=x[j];

}

Nevermind!

int[][]x = new int[6][]; should be:

int[][]x = new int[3][];
