I recently saw this algorithm in a coworker's code, and I was confused by how he used the continue statement on line 18. It seems to me that the continue will only cause the inner foreach loop to continue and not the outer loop which is what I believe was the intention.

nestedForeachContinue

foo[5] a = { 1, 2, 3, 4, 5 }; //foo is a type

foo[3] b = { 1, 2, 3 };

List<foo> unMatched = new List<foo>();

foreach (foo c in a)
{
  bool wasMatched = false;
  
  if(0 != c)
  {
    foreach (foo d in b)
    {
      if(c == d)
      {
        wasMatched = true;
        continue;
      }
    }
  }
  
  if(!wasMatched)
    unMatched.Add(c);
}
