按访问群体筛选SharePoint列表

这是我现在使用的一些代码,对我来说不太管用。根据观众的设置,我应该得到以下结果:

protected override void CreateChildControls()
{
dropdown = new DropDownList();
dropdown.Items.Add(new ListItem("Select...", ""));

SPWeb currentWeb = SPContext.Current.Site.RootWeb;
SPList shortcuts = currentWeb.Lists["Shortcuts"];

ServerContext context = ServerContext.GetContext(currentWeb.Site);
AudienceManager audManager = new AudienceManager(context);
AudienceCollection audiences = audManager.Audiences;
AudienceLoader audienceLoader = AudienceLoader.GetAudienceLoader();

foreach (SPListItem listItem in shortcuts.Items)
{
    string audienceFieldValue = (string)listItem["Target Audiences"];

    if (AudienceManager.IsCurrentUserInAudienceOf(audienceLoader, audienceFieldValue, false))
    {
        dropdown.Items.Add(new ListItem(listItem.Title, listItem.Url));
    }
}

Controls.Add(dropdown);
base.CreateChildControls();
}

关于:

if (AudienceManager.IsCurrentUserInAudienceOf(audienceLoader, audienceFieldValue, false))

它永远不会回归真实,即使它应该是。

这里有一个更简洁的代码片段。主要的更改是删除未使用的对象,以及 foreach 循环。

protected override void CreateChildControls()
{
  dropdown = new DropDownList();
  dropdown.Items.Add(new ListItem("Select...", ""));

  SPWeb currentWeb = SPContext.Current.Site.RootWeb;
  SPListItemCollection scItems = currentWeb.Lists["Shortcuts"].Items;

  AudienceLoader audienceLoader = AudienceLoader.GetAudienceLoader();

  // Iterate over a copy of the collection to prevent multiple queries to the list
  foreach (SPListItem listItem in scItems)
  {
    string audienceFieldValue = (string)listItem["Target Audiences"];

    if (AudienceManager.IsCurrentUserInAudienceOf(audienceLoader, audienceFieldValue, false))
    {
      dropdown.Items.Add(new ListItem(listItem.Title, listItem.Url));
    }
  }

  Controls.Add(dropdown);
  base.CreateChildControls();
}

下面是一个代码片段,可以用来确定每个项目的访问群体:

SPList shortcuts = currentWeb.Lists["Shortcuts"];
SPListItemCollection items = list.Items;

Audience siteAudience;

ServerContext context = ServerContext.GetContext(site);
AudienceManager audManager = new AudienceManager(context);
foreach (SPListItem item in items)
{
  string ID = item["Target Audiences"].ToString();
  string NewID = ID.Remove(36);
  Guid guid = new Guid(NewID);
  siteAudience = audManager.GetAudience(guid);
}
