Question

Just curious if I can substring string only when String.Length is greater than or equal to 20 without using If or Try catch ?

Thanks!

Answer 1

Ummh what have you tried? Just check beforehand:

if(input.Length >= 20)
{
   input = input.Substring(0,20);
}

If you really don’t want to use an if statement you could use Linq which just obfuscates the solution though and is less performant in this case:

input = new string(input.Take(20).ToArray());

Or technically this doesn’t use an if statement either:

input = input.Length >= 20 ? input.Substring(0,20) : input;
