Sharepoint：从项目事件处理程序创建子网站

Question

我有一个“项目列表”（标题、领导、成员、站点 URL），它应该引用具有项目列表的站点下的团队站点。因此，我在沙盒解决方案中的功能中添加了一个 SPItemEventReceiver 来实现此目的。

在 ItemAdding(properties) 中，我调用以下代码：

string projectName = properties.AfterProperties["Title"].ToString();
SPWeb currentWeb = properties.Web;
SPWeb subweb = currentWeb.Webs.Add(projectName, projectName, 
  "Project site for " + projectName, (uint) currentWeb.Locale.LCID, 
  Microsoft.SharePoint.SPWebTemplate.WebTemplateSTS, true, false);

但是在调试时，对 Add 的调用会抛出 SPException，其中包装了 FAILED HResult 代码的 COMException，并带有消息 沙盒代码执行请求被拒绝，因为沙盒代码主机服务太忙，无法处理该请求。

参数是否有问题，或者我应该将实际创建委托给工作流？

下面尝试一下：
公共覆盖无效 ItemAdding（SPItemEventProperties 属性）
{
base.ItemAdding(属性);

          // Get the web where the event was raised
          SPWeb spCurrentSite = properties.OpenWeb();

          //Get the name of the list where the event was raised          
          String curListName = properties.ListTitle;

          //If the list is our list named SubSites the create a new subsite directly below the current site
          if (curListName == "SubSites")
          {
              //Get the SPListItem object that raised the event
              SPListItem curItem = properties.ListItem;
              //Get the Title field from this item. This will be the name of our new subsite
              String curItemSiteName = properties.AfterProperties["Title"].ToString();
              //Get the Description field from this item. This will be the description for our new subsite
              string curItemDescription = properties.AfterProperties["Description"].ToString();
              //Update the SiteUrl field of the item, this is the URL of our new subsite
              properties.AfterProperties["SiteUrl"] = spCurrentSite.Url + "/" + curItemSiteName;

              //Create the subsite based on the template from the Solution Gallery
              SPWeb newSite = spCurrentSite.Webs.Add(curItemSiteName, curItemSiteName, curItemDescription, Convert.ToUInt16(1033), "{8FCAD92C-EF01-4127-A0B6-23008C67BA26}#1TestProject", false, false);
                 //Set the new subsite to inherit it's top navigation from the parent site, Usefalse if you do not want this.
                 newSite.Navigation.UseShared = true;
                 newSite.Close();


           }
      }

似乎出现了一些僵局的情况；我通过使用事件后 ItemAdded 解决了我的特殊情况（从 AfterProperties 中的设置值更改为更新 ListItem）。出于某种原因，对 Webs.Add() 的调用正常完成......
