How do I compare strings to see if they are composed of the same words?

Try:

using System;

class Program

{

static void Main()

{

string s1 = "Mary has a little lamp";

string s2 = "Little lamp has a Mary";

bool areSame = AreWordsSame(s1, s2);

Console.WriteLine(areSame); // True

s2 = "Mary has a big lamp";

areSame = AreWordsSame(s1, s2);

Console.WriteLine(areSame); // False

Console.ReadKey();

}

static bool AreWordsSame(string s1, string s2)

{

string[] words1 = s1.ToLower().Split(' ');

string[] words2 = s2.ToLower().Split(' ');

if (words1.Length != words2.Length) return false;

Array.Sort(words1);

Array.Sort(words2);

for(int i = 0; i < words1.Length; i++)

{

if (words1[i] != words2[i]) return false;

}

return true;

}
