Getting error of IndexOutOfRangeException in C#

Question

I am getting error of IndexOutOfRangeException in the following code.

 public static string parseVidPid()
        {
            DataSet myDs = new DataSet();

            // Get a FileStream object.
            FileStream myFs = new FileStream(PidVidPath, FileMode.Open, FileAccess.Read);

            // Apply the ReadXml(fileStream method) to read the file
            myDs.ReadXml(myFs);

            DataTable myDt = myDs.Tables[0];

            int no = myDt.Rows.Count;
            String[] nodeVal = new String[no];

            for (int i = 0; i < myDt.Rows.Count; i++)
            {
                nodeVal[i] = myDt.Rows[i].ToString();

                Console.WriteLine("Inside parseVidPid- Row = " + nodeVal[i]);
            }

            myFs.Close();

            return nodeVal[no];
        }

Where XML file is having 2 nodes. can anybody tell me where is the issue?
