Question

    string casetype6(HiddenField HiddenField1,DropDownList DropDownList3)
        {
            String casetype1="";

            try
            {
                OdbcConnection casetype = new OdbcConnection("Driver={MySQL ODBC 3.51 Driver};Server=10.155.160.130;Database=testcase;User=root;Password=;Option=3;");
                casetype.Open();

                //************to get case type    
                string casetypequery = "select casename from casetype where skey=?";

                //************to get case type
                OdbcCommand casetypecmd = new OdbcCommand(casetypequery, casetype);
                String casetypefromdropdown = DropDownList3.SelectedItem.ToString();
                casetypecmd.Parameters.AddWithValue("?", casetypefromdropdown);
                using (OdbcDataReader casetypeMyReader = casetypecmd.ExecuteReader())
                {
                    while (casetypeMyReader.Read())
                    {
                        String casename = casetypeMyReader["casename"].ToString();
                        HiddenField1.Value = casename;
                        casetype1=HiddenField1.Value.ToString();
return casetype1;
                    }
                }

            }
            catch(Exception ep)
            { }
        }

I want to use casetype1 outside this method. How can i do it?
If i say return casetype1 then error comes as:

    'Data.casetype6(System.Web.UI.WebControls.HiddenField, System.Web.UI.WebControls.DropDownList)': not all code paths return a value

Answer 1

Put return casetype1; after ending braces of catch section.
