Number format

Hi

I am using following code

decimal i = 191419

  string j = string.Format("{0:N}", i);

then the out put is  1,91,419.00 (which is correct) in en-In culture...

But When i am using the same code in client machine which is under en-GB

I am getting following output

191,419.00

but i want the out put on client machine like this  1,91,419.00

please suggest
