Question

What is the safe method to access an array element, without throwing IndexOutOfRangeException, something like TryParse, TryRead, using extension methods or LINQ?

Answer 1

You could use the following extension method.

public static bool TryGetElement<T>(this T[] array, int index, out T element) {   if ( index < array.Length ) {     element = array[index];     return true;   }   element = default(T);   return false; } 

Example:

int[] array = GetSomeArray(); int value; if ( array.TryGetElement(5, out value) ) {    ... }
