pages.isfan data fetch error

I use c# SDK to fetch pages.isfan data , but it always error.

var args=new Dictionary<string,object>();
                args["uid"] = fb_uid;
                args["page_id"] = _isfan_page_id;
                var isfanobj = (IDictionary<string, object>)fb.Api("pages.isfan", args);
                foreach 开发者_如何学JAVA(KeyValuePair<string, object> entry in isfanobj)
                {
                    Response.Write(
                        string.Format("key:{0}\nvalue:{1}\n",
                                      entry.Key,entry.Value                                          
                                     )
                    );
                }

pages.isfan need 2 parameters: page_id and uid

loop iterate my "isfanobj" , a dictionary type, the "key" always be "error".

Is my code any wrong?

If wrong, how do I get pages.isfan data?

Thanks for your help!!!

this is what I user and it works great for me.

 Dictionary<string, object> parms = new Dictionary<string, object>();
                parms.Add( "method", "pages.isFan" );
                parms.Add( "page_id", YourAppId );
                parms.Add( "uid", UsersFbId );

                var isFan = fb.Api( parms );
                if( (bool)isFan )
                {
                  //this user is a fan
                }

I find the fb.Api signature that you pass in all the parameters as a Dictionary works best for me.

I just wanted to add that when dealing with the REST API it is not the same as dealing with the Graph API you have to pass in the method as a parameter.

Also once the Rest API is fully deprecated we will all have to switch to the new method... If they ever come out with it.
