泛型 List转换成DataTable

         private DataTable listToDataTable<T>(List<T> ListItem)
         {
             //实列化DataTable对象
             var dt = new DataTable(typeof(T).Name);

             //通过反射获取List实体的属性信息
             PropertyInfo[] propertyInfos = typeof(T).GetProperties(BindingFlags.Public | BindingFlags.Instance);

             //给DataTable 添加定义
             foreach (var propertyInfo in propertyInfos)
             {
                 dt.Columns.Add(propertyInfo.Name, propertyInfo.PropertyType);
             }

             //给DataTable 添加数据
             foreach (T item in ListItem)
             {
                 var values = new object[propertyInfos.Length];
                 for (int i = ; i < propertyInfos.Length; i++)
                 {
                     values[i] = propertyInfos[i].GetValue(item);
                 }
                 dt.Rows.Add(values);
             }

             //返回DataTable
             return dt;
         }
