formating numbers from strings

[brsecu]

i have a string that always is 6 chars long. If it is not then zeros are added to it. I am pullinging this info out of the database and i need to add 1 to it. Example: I get "000456" and need to add 1 to it so its "000457" Is there an easy way to do that?

Yes, try this:

string s = "000456";
int i = -1;
if (Int32.TryParse(s, out i))
{
i +=1;
s = String.Format("{0:000000}", i);
}

This takes your string and tries to convert it to an integer value. If that succeeds, it adds 1 to it and then formats it back as a string to 6 characters padded with zeroes.

Another way: int Intvalue = Convert.ToInt32("000456") + 1; string Stringvalue = Intvalue.ToString("000000");
