没有 web 命名 - Sharepoint 事件处理程序答案

【问题标题】：There is no web named - Sharepoint Event Hander没有 web 命名 - Sharepoint 事件处理程序
【发布时间】：2012-02-17 17:31:09
【问题描述】：

我使用功能（网络级别范围）激活了以下代码。现在，当我将项目添加到任何文档库时，它应该创建一个文件夹“”。

没有创建文件夹也没有报错？谁能看到发生了什么？我从日志文件中得到以下信息。我在 google 上发现了类似的代码，所以我有点疑惑为什么在我的环境中不起作用？

谢谢

【问题讨论】：

这里有一些问题......我建议清理上面的代码示例，我们可以更好地评论。

标签： sharepoint document event-handling create-directory

【解决方案1】：

我看到了两个主要问题：

SPContext.Current.Web.Url 是网站的 url，而不是列表。
SPList 有一个 RootFolder 属性，它可能比 ToString() 更合适

【讨论】：

【解决方案2】：

SPContext.Current - 至少在我的经验中 - 出于某种原因在事件侦听器中为 null；相反，通过 SPItemEventProperties 参数中的相关属性获取当前的 SPWeb 和 SPSite（并且不要在“使用”中使用它们，因为这会使它们被丢弃以供以后处理）。
