Re: string length

Unless you're willing to count the ternary operator as different from an
if, then I can't seem to think of one.

I'm thinking of something like this:

(a.length < 250) ? a : a.Substring(0,2 50)

I know it's basically an if, but you can put it inside a conditional or
any other statement, if that's why you need to avoid ifs.

The other string functions seem to be too exception happy to do anything
to creative with. Same with StringBuilder.

public string a = Request.QuerySt ring[2].Substring(0, 250);

.... if you're willing to trap the ArgumentOutOfRa ngeException for
strings that are under 250 characters long.

and in addition to what the others said, you can also limit the input:
make sure the textbox (if that is where the text comes from)
accepts no more than 250 chars. (MaxLength property)

Re: string length

I would use:
int lengthOrTruncat ed = Math.Min(Reques t.QueryString[1].Length, 250);
string a = Request.QuerySt ring[1].Substring(0, lengthOrTruncat ed);

(or inline the temporary int variable).

Re: string length

Then how about Substring(0,min (250,length))

With a lot of work, by instance through looping thru the string and add
everytime a char untill it reaches his end,

Comparing is older in computing than multiplying, what do you think the
computer does internally when you are not using that?

Just my thought,
