You need to provide more detail, Is this WinForms ? What is 'Session ?

you also need to tell use what "this value" is. you have a session value, a list variable , and a hftreenodevalue.value field. It looks like you are already putting your values in a list. Unless you are trying to get the comma delimited values into a string list. I recommend doing a hftreenodevalue.Value.Split(",") that will at least put them in an array of strings. My thoughts, but then again I don't know that I fully understand what you are trying to accomplish.

Solution 1

Since you are storing the data in comma separated format, you should split by comma to get the string array/list

string csv = Convert.ToString(Session["idRole"]);
           List<string> list = csv.Split(',').ToList();
