推荐答案
要进行标记,您可以这样做(一个简单的例子):
To tag you can do that (a simple exemple):
private const string ExtendedPermissions = "user_about_me,user_photos,publish_stream";
[HttpPost]
[FacebookAuthorize(Permissions = ExtendedPermissions, LoginUrl = "/Home/LogOn?ReturnUrl=~/Home")]
public ActionResult MensagemPost(string message)
{
var fb = new FacebookWebClient();
dynamic me = fb.Get("me");
string friendId_1 = // get the first one friend id
string friendId_2 = // get the second one friend id
var tags = new[]
{
new { tag_uid = friendId_1, x = 20, y = 20 },
new { tag_uid = friendId_2, x = 40, y = 40 },
new { tag_uid = (string)me.id, x = 60, y = 60 }
};
dynamic parameters = new ExpandoObject();
parameters.message = message;
parameters.tags = tags;
parameters.url = "http://1.bp.blogspot.com/-evheT51sfeM/TlO_wZ8YDqI/AAAAAAAAA8I/fjlg0G8AgMY/s1600/The-best-top-hd-desktop-naruto-shippuden-wallpaper-naruto-shippuden-wallpapers-hd-11.jpg";
dynamic result = fb.Post("me/photos", parameters);
return RedirectToAction("Index", new { success = true });
}
