我创建了webpart项目，并在microsoft.sharepoint.dll 15.900版本中出错!!!

我的sharepoint服务器是独立服务器，我的webpart项目是支持框。

                var list = web.Lists["MyList"];
                var result = list.Items.Cast<SPListItem>().ToList();
                spGridView.DataSource = result;

您无法在沙盒解决方案中使用SPGridView。尝试使用GridView控件或创建自己的控件并从GridView继承它。
