We can't tell - too much depends on the content of your data, and when that code actually gets executed: and we have no control over that, nor can we test it here.

So, its going to be up to you.
Put a breakpoint on the first line in the function, and run your code through the debugger. Then look at your code, and at your data and work out what should happen manually. Then single step each line checking that what you expected to happen is exactly what did. When it isn't, that's when you have a problem, and you can back-track (or run it again and look more closely) to find out why.

Sorry, but we can't do that for you - time for you to learn a new (and very, very useful) skill: debugging!

Advice: learn to properly indent your code, it helps reading as it shows the structure.

C#

int i=0
string str1=BarCode[i].substring[0,1];
if(str1=="R")
{
	for(int j=0; j<i;j++)
	{
		if(xlworksheet.cells [j+1,2]==null)
		{
			xlworksheet.cells[j+1,2]=BarCode[i];
			break;
			else
				xlworksheet.cells[j+2,2]=BarCode[i];
		}
	}
	else if (str=="S")
	{
		for(int k=0; k<i; k++)
			if(xlworksheet.cells[k+1,3]==null)
			{
				xlworksheet.cells[k+1,3]=BarCode[i];
				break;
			}
			else
				xlworksheet.cells[k+2,3]=BarCode[i];
	}
}
}

This do not compile, the structure is wrong.
Advice: do not pack things in a single line of code, any line saved is at the expense of readability.
