facebook - Facebook c# windows 窗体：将我的 facebook 页面显示为柱形图，以通过喜欢的数量告诉用户哪个页面最受欢迎

Question

我试图将我的 Facebook 页面的点赞数显示为图表，以便用户知道哪些页面最受欢迎。我设法提取并显示我的 facebook 页面名称数据以表示图表上的颜色，我似乎无法相应地获得在 y 轴上出现的点赞数。我认为这与将我的 Json 转换为整数有关吗？任何帮助，将不胜感激！我将此链接用作图表的参考。

private void topPageBtn_Click(object sender, EventArgs e)
    {

            try
            {

                chart1.Visible = true;

                FacebookAPI api = new Facebook.FacebookAPI(myToken.Default.token);

                JSONObject pageData = api.Get("/me/accounts");

                var data = pageData.Dictionary["data"];

                List<JSONObject> pageList = data.Array.ToList<JSONObject>();

                foreach (var page in pageList)
                {
                    string[] seriesArray = { page.Dictionary["name"].String };

                    //pull more page information from the page ID
                    JSONObject pageInfo = api.Get(page.Dictionary["id"].String);

                    //store the number of likes
                    int[] pointsArray = {pageInfo.Dictionary["likes"].String};

                    // Add series.
                    for (int i = 0; i < seriesArray.Length; i++)
                    {
                        // Add series.
                        Series series = this.chart1.Series.Add(seriesArray[i]);

                        series.Points.Add(pointsArray[i]);
                    }
                }


                // Set palette.
                this.chart1.Palette = ChartColorPalette.EarthTones;

                // Set title.
                this.chart1.Titles.Add("No. of Page likes");


            }
            catch (Exception ex)
            {
                MessageBox.Show(ex.Message);
            }

    }

        try
        {

            chart1.Visible = true;

            FacebookAPI api = new Facebook.FacebookAPI(myToken.Default.token);

            JSONObject pageData = api.Get("/me/accounts");

            var data = pageData.Dictionary["data"];

            List<JSONObject> pageList = data.Array.ToList<JSONObject>();

            foreach (var page in pageList)
            {
                string[] seriesArray = { page.Dictionary["name"].String };

                //pull more page information from the selected ID
                JSONObject pageInfo = api.Get(page.Dictionary["id"].String);

                //
                //store the number of likes


                // Add series.
                for (int i = 0; i < seriesArray.Length; i++)
                {
                    // Add series.
                    Series series = this.chart1.Series.Add(seriesArray[i]);

                    int[] pointsArray = new int[seriesArray.Length];
                    pointsArray[i] = Convert.ToInt32(pageInfo.Dictionary["likes"].Integer);
                    series.Points.Add(pointsArray[i]);
                }
            }

            // Set palette.
            //  this.chart1.Palette = ChartColorPalette.EarthTones;

            // Set title.
            this.chart1.Titles.Add("No. of Fans"); 
        }
        catch (Exception ex)
        {
            MessageBox.Show(ex.Message);
        }
