備註

這個類別做為橋樑List和外部清單。使用相關聯的List擷取實體欄位和資料。

從 [ HasExternalDataSource ] 屬性中擷取ListDataSource的執行個體。HasExternalDataSource不是空值，就外部Microsoft SharePoint FoundationList物件的資料。

範例

此程式碼範例示範會列出在指定的網站上是外部項目。

using System;
using Microsoft.SharePoint.Client;

namespace Microsoft.SDK.SharePointFoundation.Samples
{
    class ListDataSourceExample
    {
        static void Main()
        {
            string siteUrl = "http://MyServer/sites/MySiteCollection";

            ClientContext clientContext = new ClientContext(siteUrl);
            Web site = clientContext.Web;
            clientContext.Load(site);
            ListCollection collList = site.Lists;
            clientContext.Load(
               collList,
               lists => lists
                  .Include(
                     list => list.Title,
                     list => list.DataSource)
               ); 
            clientContext.ExecuteQuery();

            string messageExternal = "External Lists:\n";
            string messageNormal = "Normal Lists:\n";
            foreach (List targetList in collList)
               if (targetList.DataSource != null)
               {
                  // Get connection properties of the ListDataSource object.
                  messageExternal += "\n\t" + targetList.Title
                     + "(Entity=" + targetList.DataSource.Properties["Entity"] + "; "
                     + "LOB System=" + targetList.DataSource.Properties["LobSystemInstance"];
               }
               else
               {
                  messageNormal += "\n\t" + targetList.Title;
               }
            Console.WriteLine(messageExternal);
            Console.WriteLine(messageNormal);
        }
    }
}
