[CS]Method Name Expected while using Linq with Lambda Expression RRS feed

  • Question

  • I am partially new to C# (I have done basics with it, but most of my experience is with VB.NET), and am working on converting my VB.NET code to C# (I am converting my UWP apps to Xamarin, and all my UWP codebehind was written using VB.NET). I am trying to convert the following VB.NET to C#:
    Imports Xamarin.Forms
    Public Class Class1
    	Public Sub Testing()
    		Dim fl As New FlexLayout()
    		Dim tempbtn As View
    		tempbtn = fl.Children.Where(Function(btn) btn Is GetType(Grid))(0)
    	End Sub
    End Class
    I thought that this would be similar to the following:
    tempbtn = fl.Children.Where(btn => btn.GetType() == typeof(Grid))(0);
    However, Visual Studio 2019 is giving me the message "Method Name Expected". What am I doing wrong? Thanks.

  • Hi,

    You will need to change the (0) to FirstOrDefault() in C#.

    Like this:

    tempbtn = fl.Children.Where(btn => btn.GetType() == typeof(Grid)).FirstOrDefault();

    Best regards,
