如何將Web部件定位到觀衆

Question

嗨，我是新的SharePoint人員。如何以編程方式將Web部件定位到受衆羣體可以提供任何答案。

按本link：

提供權限爲特定SharePoint組在SharePoint Web部件，我們必須使用AudienceManager如下圖所示

SPWeb currentSite = SPContext.Current.Site.RootWeb; 
SPSite spSite = currentSite.Site; 

SPServiceContext sc = SPServiceContext.GetContext(spSite); 
AudienceManager am = new AudienceManager(sc); 

Microsoft.SharePoint.WebPartPages.SPLimitedWebPartManager mgr = null; 
mgr = currentSite.GetLimitedWebPartManager("SitePages" + "/" + page,   
     System.Web.UI.WebControls.WebParts.PersonalizationScope.Shared); 
foreach (System.Web.UI.WebControls.WebParts.WebPart webPart in mgr.WebParts) 
{ 
    if (webPart.Title == "WebPartTitle") 
    { 
      //Get the Existing Audience for the Web Part 
      string audWebPart = webPart.AuthorizationFilter; 
      //If there is no Audience for the Web Part just add it 
      if (audWebPart == "") 
      { 
       webPart.AuthorizationFilter = ";;;;" + NewAudience; 
      } 
      //If already Audiences are exist for the Web Part then append new Audience 
      else 
      { 
       webPart.AuthorizationFilter = audWebPart + "," + NewAudience; 
      } 
      mgr.SaveChanges(webPart); 
      lblMessage.Text = "Succeeded..."; 
    } 
} 

如果我們只是設定AuthorizationFilter屬性的值，那麼現有的受衆羣體將被覆蓋。 爲了避免它首先，我們必須檢查該Web部件是否已有受衆羣體。如果是這樣，我們必須追加它。

SharePoint Server 2010框架要求三種值由一對分號（「;;」）分隔。全局受衆羣體和SharePoint羣組的多個值由逗號分隔，並且分配列表的多個值由換行符（「\ n」）分隔。因此在上面的例子中我們使用了「;;;;」爲AuthorizationFilter屬性提供有效的字符串。
