As I know if I declared a dictionary, I could call myDict.Clear () to reuse the target.
Now, if I declared sb as a StingBuilder obj object.
StringBuilder sb = new StringBuilder();
How to reuse sb? thanks.
Basically, I need to print all the possible conditions for mainDict.
one of the sb expressions like this (in the code below)
sb.AppendFormat("{0}/{1}/{2}/{3}, {4}", pair1.Key, pair2.Key, pair3.Key, pair4.Key, pair4.Value);
Console.WriteLine(sb.ToString());
If I declared many StringBuilder objects, I still cannot determine how many objects are enough for me. Actuarial mainDict is very complex. The above code is a practice. thanks.

A conclusion like this
SubKey = FKey, Value = FValue
ADKey/BDKey/CDKey/DDKey/EDKey/FKey, FValue
SubKey = ESKey, Value = EValue
ADKey/BDKey/CDKey/DDKey/ESKey, EValue
SubKey = DSKey, Value = DValue
ADKey/BDKey/CDKey/DSKey, DValue
SubKey = CSKey, Value = CValue
ADKey/BDKey/CSKey, CValue
SubKey = BSKey, Value = BValue
ADKey/BSKey, BValue
Key = ASKey, Value = AValue
ASKey, AValue
