{
    [Guid("c154fc8b-eb18-4db3-890f-2f6e82908f29")]

        }
        public override void RenderControl(HtmlTextWriter writer)

            //base.RenderControl(writer);
            RenderChildren(writer);
        }

    }
}

推荐答案

在不知道错误是什么的情况下，我猜这是因为这一行

Without knowing what the error is I would guess it is because of this line

ad.AdvertisementFile = "~/XMLFile1.xml";

SharePoint不像ASP.NET应用程序.您无需将文件放在IIS应用程序路径中，它们是通过库或列表来自内容数据库的，还是来自布局文件夹的文件.

我怀疑您需要先尝试了解SharePoint上的一些文档，然后再尝试为其创建Webparts.

SharePoint is not like an ASP.NET application. You don''t place files in the IIS application path, they come from the content database via libraries or lists or from the layouts folder.

I suspect you need to read through some documentation on SharePoint before trying to create webparts for it.
