How do I find the longest word in a Visual Basic array?

Question

I have an array in Visual Basic that needs to have the longest word returned. How do I go about locating the longest word in a String array? Any help is greatly appreciated!

Answer 1

Dim longestWord = String.Empty

For Each word in strArray
    If Not String.IsNullOrEmpty(word) AndAlso word.Length > longestWord.Length Then
        longestWord = word
    End If        
Next

** updated to account for null string **

Answer 2

A LINQ alternative is this:

Dim strings = New String() {"1", "02", "003", "0004", "00005"}

Dim longest As String = strings.OrderByDescending(Function(s) s.Length).FirstOrDefault()

Answer 3

Something like this... (It's c#, but should port to VB easily)

string[] stringArray = new string[] { "One", "Two", "Three", "Four" };
string longest = stringArray.OrderByDescending(x => x.Length).FirstOrDefault();

Answer 4

If I were to do this with Linq in C#, I would do it something like this:

var strings = new string[3] { "abc", "defg", "hijkl" };
string longest = strings.OrderByDescending(s => s.Length).FirstOrDefault();
