Description
Example of what it looks like today (see bottom line of documentation):
// .........
// Exceptions:
// T:System.ArgumentNullException:
// array is null. -or- match is null.
//
// T:System.ArgumentOutOfRangeException:
// startIndex is outside the range of valid indexes for array.
public static int FindIndex<T>(T[] array, int startIndex, Predicate<T> match);It effectively says that the method accepts [0 <= startIndex < Length] with Length exclusive.
But what the method actually accepts is [0 <= startIndex <= Length] with Length inclusive.
The real behavior of the startIndex is identical to String.Substring, which has the following description instead:
// T:System.ArgumentOutOfRangeException:
// startIndex is less than zero or greater than the length of this instance.To be correct and easy to understand the FindIndex documentation should thus say:
// startIndex is less than zero or greater than the length of the array.
