assign dynamic arrayTodataTable using C#.net for Google column chart.

Hi,

private void BindColumnChart()
    {
        DataTable dt = new DataTable(); StringBuilder str = new StringBuilder();
        try
        {
            var q = string.Empty;
            q =
@"SELECT	 dbo.SubjectMaster.SubjectName
            		,dbo.QuestionPaper.Division
            		,dbo.QuestionPaperDetail.Marks
            FROM	 dbo.QuestionPaper 
            		INNER JOIN dbo.SubjectMaster ON dbo.QuestionPaper.SubjectId = dbo.SubjectMaster.SubjectId 
            		INNER JOIN dbo.QuestionPaperDetail ON dbo.QuestionPaper.QuestionPaperId = dbo.QuestionPaperDetail.QuestionPaperId
            WHERE   (dbo.QuestionPaper.Semister = '1') AND (dbo.QuestionPaper.[Standard] = '9')
            GROUP BY dbo.SubjectMaster.SubjectName,dbo.QuestionPaper.Division,dbo.QuestionPaperDetail.Marks";

            DataSet ds = SqlHelper.ExecuteDataset(ObjCnp.getConnect(), CommandType.Text, q.ToString(), null);
            dt = ds.Tables[0].Copy();

            //-------------------------------------------------------------------------------------
            //List<string> result = new List<string>();
            System.Collections.ArrayList result = new System.Collections.ArrayList();
            foreach (DataRow dtrow in ds.Tables[0].Rows)
            {
                result.Add(dtrow);
            }

            str.Append(@"<script type='text/javascript'>
                    google.load('visualization', '1', { packages: ['corechart'] });
                    function drawVisualization() {
                        var data = google.visualization.arrayToDataTable([ // Create and populate the data table.
//                          ['Subject', 'A', 'B', 'C', 'D', 'E', 'F'],

//                          ['Science', 20, 50, 30, 80, 50, 90],
//                          ['Hindi', 100, 20, 30, 80, 50, 30]
                        ]);
                        new google.visualization.ColumnChart(document.getElementById('visualization')). // Create and draw the visualization.
                            draw(data,
                                 {
                                     title: 'Semister Marks Obtainded by Subject',
                                     width: 600, height: 400,
                                     hAxis: { title: 'Subject' }
                                 }
                            );
                    }
                    google.setOnLoadCallback(drawVisualization);</script>");

            //var stringArr = dt.Rows[0].ItemArray.Select(x => x.ToString()).ToArray();
            ct.Text = str.ToString().TrimEnd(',').Replace('*', '"');
        }
        catch
        { }
    }

if i uncomment the array then it will work fine.
