Question

In the below piece of code, is there a way to not need a foreach? All that needs to happen is that if a single of the split parts exceeds a length, i can set it as invalid.

My colleage is sure he used a one line piece of code for this but google left me with no evidence of this.

                else if (lineSplit[11].Length > Constant.EstimatedBirthdatesofChildren)
            {
                var estimatedBirthdatesofChildren = lineSplit[11].Split('~');
                foreach (String estimatedBirthdatesofChild in estimatedBirthdatesofChildren)
                {
                    if (estimatedBirthdatesofChild.Length > Constant.EstimatedBirthdatesofChild) valid = false;
                }
            }

Answer 1

lineSplit[11].Split('~').Max(s => s.Length)

Oops, you mean you need the first token having more than expected length? your question is not clear, but if yes, you can write

valid = lineSplit[11].Split('~').Any(s => s.Length > Constant.EstimatedBirthdatesofChild)
