Retrieve an object that has a member variable with the longest string length

Question

Given a Generic List of objects that contain a member variable that is a string, what is the best way to get the object that contains the string with the longest length?

ie. assuming val1 is the string I'm comparing:

0 : { val1 = "a"   }
1 : { val1 = "aa"  }
2 : { val1 = "aba" }
3 : { val1 = "c"   }

what needs to be returned is object 2 because "aba" has the greatest length.

Answer 1

Sorry, I'll try again. You can use the following aggregation:

Dim result = elements.Aggregate(Function(a, b) If(a.val1.Length > b.val1.Length, a, b))

Answer 2

You could also use an order-by:

var x = myStringArray.OrderBy(s => s.Length).Last();

Answer 3

Dim longestLength = elements.Max(Function(el) el.val1.Length)
Dim longest = elements.First(Function(el) el.val1.Length = longestLength)
