chosen.content: Here is a C# function that reverses the case in a string as you requested:
  
  string ReverseCase(string s)
  {
          StringBuilder reversedString = new StringBuilder();
          foreach(var letter in s)
          {
                  if(!char.IsLetter(letter))
                  {
                          reversedString.Append(letter);
                          continue;
                  }
                  if(char.IsUpper(letter))
                  {
                          reversedString.Append(char.ToLower(letter));
                  }
                  if(char.IsLower(letter))
                  {
                          reversedString.Append(char.ToUpper(letter));
                  }
          }
          
          return reversedString.ToString();
  }
