Question

我正在使用帶有VB的facebook-c＃-sdk。

我的代碼：

dim facebook As New FacebookApp() 

dim queries as string=" ""2011-4-13"" : ""SELECT metric, value FROM insights WHERE object_id=173249789387842 AND metric='page_active_users' AND end_time=end_time_date('2011-4-13') AND period=period('day')"",""2011-4-14"" : ""SELECT metric, value FROM insights WHERE object_id=173249789387842 AND metric='page_active_users' AND end_time=end_time_date('2011-4-14') AND period=period('day')""" 

dim oFQLResult As Object = facebook.Query(queries) 

我得到：Facebook.FacebookApiException：分析器錯誤：意外的 '\' 在位置0

單查詢工作完美。什麼是進行多查詢的正確方法？

謝謝！

你可能想看看這些nuget包。 （樣本在C＃中）

Install-Package Facebook.Sample 
Install-Package Facebook.Sample.Dynamic 

這裏是C＃中的示例。

 var query1 = "SELECT uid FROM user WHERE uid=me()"; 
     var query2 = "SELECT profile_url FROM user WHERE uid=me()"; 

     try 
     { 
      var fb = new FacebookClient(accessToken); 

      var result = (IList<object>)fb.Query(query1, query2); 

      var result0 = ((IDictionary<string, object>)result[0])["fql_result_set"]; 
      var result1 = ((IDictionary<string, object>)result[1])["fql_result_set"]; 
     } 
     catch (FacebookApiException ex) 
     { 
      // Note: make sure to handle this exception. 
      throw; 
     }
