C＃声明静态列表

Question

I am using a Static List to store some values, the idea is declare the list, then a button in page 1 adds some values, then a button in page 2 adds some more values, to do this I am triying declare it in each page but the list is newly created:

public static List _songlist = new List(); in each page.

Can you help me?, how I can declare the static list then have the same list with the values in all the pages?

public static List<Song> _songlist = new List<Song>();

public class Song
{
private string _name;
public string name
{
get { return _name; }
set { SetProperty(ref _name, value); }
}
private string _artist;
public string artist
{
get { return _artist; }
set { SetProperty(ref _artist, value); }
}
}

Any help is appreciated.

Answer 1

If I understand you, you want an Application wide static list.

Why not create a new file called ApplicationServices.cs and put a static class inside of it with a static List<Song>

public static class ApplicationServices{
      public static List<Song> Songs {get; set;}
}

This way you can access it everywhere by calling ApplicationServices.Songs
