Converting a string to int and back

[radarmy]

Hey,

I am having some difficulties converting a string which contains numbers into an integer and then dividing the number by 15 then converting the result back to a string.

I'm pretty sure I am way off and stuff but this is what I got:

Nums[intX]=(string)Convert.ChangeType((int)Convert.ChangeType(Nums[intX], typeof(int))/15, typeof(string));

The error that I am getting is: System.FormatException: Input string was not in a correct format.

I'm probably not using the ChangeType method properly so any help is greatly appriciated.

Try that:
Nums[intX] = (int)(int.Parse(Nums[intX])/15).toString()

I haven't verified it works, so if it doesn't, look into the parse() method of the integer object. It will parse a string into a integer.

Same error, I did change it so it dumps the result into an integer array so it doesn't need to convert it back to a string.

This is my new code:
ActualNums[intX] = (int)(int.Parse(Nums[intX])/15);

and I still get: System.FormatException: Input string was not in a correct format.

And I checked and the Nums[] array is a string; however when I try this:
ActualNums[intX] = (int)(int.Parse("555")/15);

It works...

TIA
