Cannot convert from 'Xamarin.Forms.Entry' to 'Tweetinvi.Models.IUserIdentifier' - xamarin

Question

I have been trying to use the x:name of the entry field to store the username of a twitter user and then using it for accessing the feeds. But I'm facing this error: cannot convert from 'Xamarin.Forms.Entry' to 'Tweetinvi.Models.IUserIdentifier'. What to do?
XAML File

<StackLayout VerticalOptions="CenterAndExpand" HorizontalOptions="CenterAndExpand">
<Entry x:Name="twitteruser_entry" Placeholder="#Username"></Entry>
</StackLayout>
</ContentPage.Content> </ContentPage>

{
[XamlCompilation(XamlCompilationOptions.Compile)]
public partial class AnalysisPage : ContentPage
{
public AnalysisPage ()
{
var user_identifier = twitteruser_entry; //this is where i'm getting the error.
var User = (dynamic)null;
var authenticatedUser = User.GetAuthenticatedUser();
var tweets = Timeline.GetUserTimeline(user_identifier, 10);
}
}
}

This is failing because it is trying all of the overloads and only returns the error on the last one.
Given the name of the field I am going to assume that the user is going to enter their username into the field. In this case you are probably wanting this overload
public static IEnumerable<ITweet> GetUserTimeline(string userScreenName, IUserTimelineParameters userTimelineParameters)
If this is the case, you need to get the text from the entry and pass it to that method.
var tweets = Timeline.GetUserTimeline(user_identifier.Text, 10);
