As per your s1, s2 strings
string myString = s1.Remove(s1.IndexOf(s2),s2.Length+1);

It will remove only one occurrence..

You can use the below code:-

string s1 = "2,3,4,5";
string s2 = "4";
string newone = str.Replace(s2 + ",", "");

You can also use the below code:-

string s1 = "2,3,4,5";

string s2 = "4";
List<string> result = s1.Split(new char[] { ',' }).ToList();
result.Remove(s2);
string output = string.Join(",", result.ToArray());

Two approaches:
1) string myString = s1.Remove(s1.IndexOf(s2),s2.Length+1); 

2) string myString = s1.Replace(s2 + ",", "");

the above are easy approaches....
The approach using List and Remove is the lengthy process
