Ever looked at the methods of the String class? There are several you could use.

Hope This helps you :

string str6= "I,II,III,IV";
string[] str4 = str6.Split(',');

string ss=Array.Find<string>(str4, el => el.StartsWith("II"));

Overkill in a huge way. Just use the built in .Contains method.

If you want false for "I,III,IV,V", use

exp.Split(",").Contains("II")

if you want true for "I,III,IV,V", then use

exp.Contains("II")
