我正在尝试在我朋友的时间线上发布一些内容，但每次我尝试这样做时都会出现错误。我正在使用的代码如下。我想知道代码是否正确？因为它对我不起作用。你能帮我吗？
dynamic parameters = new ExpandoObject();
if (!string.IsNullOrEmpty(action.Post.PictureLocalSource))
{
var pictureTracking = GetNextPhotoFromFolder(action.Post.PictureLocalSource);
if (pictureTracking != null)
{
// action.Post.Picture = pictureTracking.FBPictureRef; // org
action.Post.Link = pictureTracking.FBPictureRef;
action.Post.Picture = pictureTracking.TrackingFileName;
parameters.type = "";
}
}
parameters.to = action.FacebookPostTargetID;
//parameters.Add("from", MyFacebookID);
parameters.message=action.Post.Message.Trim();
parameters.link = action.Post.Link;
parameters.picture = action.Post.Picture;
parameters.source = action.Post.Source;
parameters.name = action.Post.Name;
string caption = action.Post.Caption;
if (caption.Length > 200)
caption = caption.Substring(0, 200);
parameters.caption = caption.Trim(); // "Σχετικά με το asfame.gr";
parameters.description=action.Post.Description;
string feedtype = "";
if (action.Type == ActionType.Comments)
feedtype = "comments";
else
feedtype = "feed";
parameters.method = feedtype;
result = Client.Post(parameters);
