WPF动态类动态表头实现排序

采用了动态类的表格我们要显示排序的话也需要使用反射来实现，关键代码如下：

private void TextBlockMouseLeftButtonDown(object sender, MouseButtonEventArgs e)
        {
            TextBlock textBlock = sender as TextBlock;
            string proname = textBlock.Tag.ToString();

            if (isclicked == false)
            {
                HeadmasterDayReportModels = HeadmasterDayReportModels.OrderBy(x =>
                {
                    PropertyInfo[] proInfos = x.GetType().GetProperties();
                    PropertyInfo pi = proInfos.Where(info => info.Name == "DicProperty").FirstOrDefault();
                    Dictionary<string, object> pairs = pi.GetValue(x, null) as Dictionary<string, object>;
                    return Convert.ToDouble(pairs.Where(pa => pa.Key == proname).ToList()[0].Value.ToString().Replace("%", ""));
                }).ToList();
              
                this.headmastergrid.ItemsSource = HeadmasterDayReportModels;
                isclicked = true;
            }
            else
            {
                HeadmasterDayReportModels = HeadmasterDayReportModels.OrderByDescending(x =>
                {
                    PropertyInfo[] proInfos = x.GetType().GetProperties();
                    PropertyInfo pi = proInfos.Where(info => info.Name == "DicProperty").FirstOrDefault();
                    Dictionary<string, object> pairs = pi.GetValue(x, null) as Dictionary<string, object>;
                    return Convert.ToDouble(pairs.Where(pa => pa.Key == proname).ToList()[0].Value.ToString().Replace("%",""));
                }).ToList();

                this.headmastergrid.ItemsSource = HeadmasterDayReportModels;
                isclicked = false;
            }
        }
