Compare Two List of Strings in C# and VB.NET

Imagine you have two List<String>. You want to quickly compare them to see if all the elements match each other. Here's how to do so:


List<string> strList1 = new List<string>


    "Jack", "And", "Jill", "Went", "Up", "The", "Hill"



List<string> strList2 = new List<string>


    "Jack", "And", "Jill", "Went", "Down", "The", "Hill"



bool result = strList1.SequenceEqual(strList2);


        Dim strList1 As List(Of String) = New List(Of String)(New String() _

        {"Jack", "And", "Jill", "Went", "Up", "The", "Hill"})


        Dim strList2 As List(Of String) = New List(Of String)(New String() _

         {"Jack", "And", "Jill", "Went", "Down", "The", "Hill"})


        Dim result As Boolean = strList1.SequenceEqual(strList2)

Remember that this search is case sensitive!
