Answer 1

You can use Substring to get both parts separately.

First, you use IndexOf to get the position of the first comma, then you split it :

string input = "101,a,b,c,d";
int firstCommaIndex = input.IndexOf(',');

string firstPart = input.Substring(0, firstCommaIndex); //101
string secondPart = input.Substring(firstCommaIndex + 1); //a,b,c,d

On the second part, the +1 is to avoid including the comma.
