Wrote a piece of code to write Numbers in the text file, and then should write 22 is, however, only wrote about 20 line stops,
Request a great god answer

This is the cycle code:

 
for (int i=0; I & lt; Sumx; I++) 
{
For (int j=0; J & lt; Sumy; J++) 
{
Grd1. Write (IFF [I, j]); 
Grd1. Write (" "); 
} 
Grd1. Write (' \ n '); 
} 

Sumx=22
Sumy=18
This
In fact, even if changing sumx to number 22, also can only be read in 20 lines...

The complete code is this:
