C#

string vertex = "select vertex_path from Tbl_AllGraphInfo where Graph_Id='" + Graph_Id + "'";
            SqlCommand cmd = new SqlCommand(vertex,con11);
            con11.Open();
            SqlDataReader dr = cmd.ExecuteReader();
            while (dr.Read())
            {
                fullpath = dr.GetString(0);

            }
            dr.Close();
//            string actresult = ((string)cmd.ExecuteScalar());
            con11.Close();
            int counter = 0;
            string[] array = fullpath.Split(';');
            string[] array2 = new string[2];
            List<string> list = new List<string>();
            for (int i = 0; i < array.Length; i++)
            {
               array2= array[i].Split(',');
               list.Add(array2[1]);


            }
            counter = 0;

            string[] pattern = (string[])list.ToArray();

What I have tried:

Index was outside the bounds of the array

Use the debugger and step through your application: we can't do that as we don't have access to your data.
Put a breakpoint on the first line of that code, and run it in the debugger. When execution reaches the breakpoint it will stop and let you have control. Use the debugger to examine variable contents, and step through the program line by line, working out what you expect to happen before you execute each one.
Did you what expected happen? If so, continue with the next line. If not, why not? What did happen? What was in the variables that causes this to happen?

We can't do any of this for you - we don't have access to your data, and I don't think the error is in that code - it occurs on a line you haven't shown us. So give it a try, and see what you can find out!

BTW: Do not concatenate strings to build a SQL command. It leaves you wide open to accidental or deliberate SQL Injection attack which can destroy your entire database. Use Parametrized queries instead.
