问如何用一个以上的括号分割字符串

EN

          string test = "((12-5=10)&&(5-4>6))";
        string[] Arr= test.Split(new string[{"(",")"},StringSplitOptions.RemoveEmptyEntries);
        List<string> newArr = new List<string>();
         int h=0;
        foreach (string s in Arr)           
        { 
            if (s != "&&")
                newArr.Add( s.Replace(s, "(" + s + ")"));
            else 
                newArr.Add(s);
            h++;
        }
        newArr.Insert(0, "(");
        newArr.Insert(newArr.Count , ")");

initialize depth and start to 0
for each character  
  if it is ( increase depth
  if it is ) 
     decrease depth
     if depth is 0
         parse the substring from start to current character
         set start to current character
