将带有子字符串的字符串按正确的顺序转换为对象列表

问：

好的，我有一种复杂的字符串列表，我需要将其转换为新的输出。我觉得我可能走错了路，或者它就是这么复杂？它会做大部分的事情，但是一旦它完成第三个循环并返回第二个循环，它就会添加一个空对象，然后再次添加第三个对象并出错。有没有其他方法可以做到这一点或修复我所拥有的？

任何帮助或想法都会很棒:(

注意：字符串中的名称为隐私而更改，它们通常不是 string1 等。

(String1, string2, string3, string4(string5, string6, string7(c1, c2, c3)), string8)

TO

- string1
- string2
- string3
- string4
  - string5
  - string6
  - string7
    - c1
    - c2
    - c3
-string8

我的代码

 public List<object> ParseOutput(string parseString) {
    List<object> sortedList = new List<object>();

    int indexFirstLoop = 0;
    int indexSecondLoop = 0;
    int indexThirdLoop = 0;
    int stringLength = parseString.Length - 1;

    //Iternate through string to find comma seperated words
    for (int a = 0; a < parseString.Length; a++)
        {
            //Hits a comma, take word before comma and add to array
            if(parseString[a] == ','){
                //get word before comma and put into array
                sortedList.Add(parseString.Substring(indexFirstLoop, a - indexFirstLoop).Trim());
                indexFirstLoop = a + 1;
            }
            //If hits open parenthesis then go to next section and loop through those strings
            else if(parseString[a] == '('){
                var secondString = parseString.Substring(a + 1, stringLength - a);
                var secondList = new List<string>();
                //Second Loop
                for (int b = 0; b < secondString.Length; b++)
                {
                    //Hits a comma, take word before comma and add to array
                    if(secondString[b] != ')'){
                        if(secondString[b] == ','){
                            secondList.Add(secondString.Substring(indexSecondLoop, b - indexSecondLoop).Trim());
                            indexSecondLoop = b + 1;
                        }
                    
                    //If hits open parenthesis inside first parentethsis, then go to next section and loop through those strings
                    else if(parseString[b] == '('){
                        var secondStringLength = secondString.Length;

                        var thirdList = new List<string>();
                        //Third Loop
                        for (int c = 0; c < thirdString.Length; c++)
                        {

                                indexThirdLoop = c + 1;
                            }
                        } //End Last Loop
                        if(thirdList.Count > 0){
                            sortedList.Add(thirdList);
                        }
                    } //End Second Parenthesis Loop
                    }
                }//End Second Loop

                if(secondList.Count > 0){
                    sortedList.Add(secondList);
                }

            } //End First Parenthesis Loop
        } //End First Loop

    return sortedList;
