To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

The Grade of the Solution

I'm trying this and it isn't working:

strWordingCode = "test1,"
Session["DuplicateForms"] = Session["DuplicateForms"].ToString().Replace(" + strWordingCode + ","");

" + strWordingCode + " would look for the string literal " + strWordingCode + ". remove the quotations and the pluses:
string strWordingCode = "test1,";
Session["DuplicateForms"] = Session["DuplicateForms"].ToString().Replace(strWordingCode,"");

jaime_olivares:

You have to divide your problems in parts:

strWordingCode = "test1"; // without comma
string list = Session["DuplicateForms"].ToString();
List<string> parts = new List<string>(list.Split(','));
for (int i=0; i<parts.Length;)
{
if (parts[i]==strWordingCode)
parts.RemoveAt(i);
else
i++;
}
Session["DuplicateForms"] = string.Join(",", parts.ToArray());

Velio, thanks that worked, but actually my requirements changed a little, if the wording code appears more than once in the string, i only want to remove it once.. so

test1,test2,test3,test1,

I want to remove ONCE instances of "test1," so i would have

test2,test3,test1,

jaime_olivares, I wasn't able to test out your code because it was giving me errors where the > are... I'm using asp.net 1.1... could that be a problem? It looks like your code might work, but I'm not sure how to convert it to work with asp.net....

Rank: Wizard

Velio:

the helper method below will do that.

your code would be something like this:
string strWordingCode = "test1,";
Session["DuplicateForms"] = RemoveFirst(Session["DuplicateForms"].ToString(), strWordingCode);

         
                 public static string RemoveFirst(string str, string remove)
    {
        int index = str.IndexOf(remove);
        if (index == -1)
            return str;
        return str.Remove(index, remove.Length);
    }
