C# + longest streak in strings

//Longest streak of chars in a string...should return 4(d's)

      //1st time that 2 positions match
      else if (!dict.ContainsKey(currentLetter))                   
      {

  //Alternately --Take(1) highest count -or- var singleEntryDict = ordered.First();
  var result = ordered.Take(3).ToDictionary(d => d.Key, d => d.Value);
