        "content": "Below is a complete example of a simple Windows desktop application in C# (using WinForms) that lets the user browse through a list of TV streaming stations around the world, select one, play it (stream it), and at the end save a selected station list to a file on disk. You can compile this in Visual Studio or using the .NET SDK, run on Windows. You\u2019ll need .NET Framework or .NET 6+ installed.\n\nBecause streaming actual TV stations involves URLs to media streams, we\u2019ll assume you have an API or data source of streaming station metadata (name, country, stream URL). This example uses a simple in-memory list; you can extend it to fetch from the web.\n\n---\n\n## What the program does\n\n- Displays a list of TV stations with name and country.\n- Plays the selected station\u2019s stream in a media player control.\n- Allows you to save a list of your favorite/selected stations into a file (JSON).\n- Allows loading previously saved lists.\n\n---\n\n## Prerequisites\n\n- Windows PC\n- .NET 6.0 SDK (or .NET 5 / .NET Core that supports WinForms)\n- Visual Studio 2022 (or later), or Visual Studio Code + C# plugin\n- A media playing component/control that can play streaming URLs. We\u2019ll use `Windows Media Player` COM control for simplicity.\n\n---\n\n## Full Source Code\n\nCreate a new **Windows Forms App** (.NET 6) project. Call it `TVStreamer`.\n\n### Program.cs\n\n```csharp\nusing System;\nusing System.Windows.Forms;\n\nnamespace TVStreamer\n{\n    static class Program\n    {\n        [STAThread]\n        static void Main()\n        {\n            Application.SetHighDpiMode( HighDpiMode.SystemAware );\n            Application.EnableVisualStyles();\n            Application.SetCompatibleTextRenderingDefault( false );\n            Application.Run( new MainForm() );\n        }\n    }\n}\n```\n\n### MainForm.cs\n\n```csharp\nusing System;\nusing System.Collections.Generic;\nusing System.IO;\nusing System.Text.Json;\nusing System.Windows.Forms;\n\nnamespace TVStreamer\n{\n    public partial class MainForm : Form\n    {\n        private List<TVStation> allStations = new List<TVStation>();\n        private List<TVStation> favoriteStations = new List<TVStation>();\n\n        public MainForm()\n        {\n            InitializeComponent();\n            LoadStations();\n            PopulateStationList();\n        }\n\n        private void LoadStations()\n        {\n            // Example hard-coded stations;

set; }\n        public string Country { get; set; }\n        public string StreamUrl { get; set; }\n\n        public override bool Equals( object obj )\n        {\n            if ( obj is TVStation other )\n            {\n                return StreamUrl == other.StreamUrl;\n            }\n            return false;\n        }\n        public override int GetHashCode()\n        {\n            return StreamUrl != null ? StreamUrl.GetHashCode() : 0;\n        }\n    }\n}\n```\n\n### MainForm.Designer.cs\n\nYou need a WinForms designer with:\n\n- `ListBox listBoxStations` \u2014 to show all stations\n- `ListBox listBoxFavorites` \u2014 to show your favorites\n- `Button buttonAddFavorite` \u2014 \u201cAdd to Favorites\u201d\n- `Button buttonSaveFavorites` \u2014 \u201cSave Favorites\u201d\n- `Button buttonLoadFavorites` \u2014 \u201cLoad Favorites\u201d\n- `AxWMPLib.AxWindowsMediaPlayer axWindowsMediaPlayer` \u2014 Windows Media Player control to play the stream\n\nUse the designer to place them, set their names matching above, wire up events:\n\n- `listBoxStations.SelectedIndexChanged += listBoxStations_SelectedIndexChanged`\n- `buttonAddFavorite.Click += buttonAddFavorite_Click`\n- `buttonSaveFavorites.Click += buttonSaveFavorites_Click`\n- `buttonLoadFavorites.Click += buttonLoadFavorites_Click`\n\n---\n\n## How to Compile\n\n1. Open Visual Studio \u2192 Create new **Windows Forms App** (.NET 6 or 7).\n2. Add a reference to Windows Media Player COM component:\n   - In Solution Explorer: right-click References \u2192 Add COM Reference \u2192 find \u201cWindows Media Player\u201d \u2192 OK\n   - In the form designer toolbox, add the \u201cWindows Media Player\u201d control to the form.\n3. Add the three `.cs` files (`TVStation.cs`, `MainForm.cs`, `Program.cs`) and the designer parts.\n4. Ensure namespaces and class names match.\n5. Build Solution (`Ctrl+Shift+B`) \u2013 should compile without errors.\n6. Run `F5` to test.\n\n---\n\n## Extending / Real World Use\n\n- Replace hard-coded list with a dynamic source: read from an online API or static file listing global TV streaming stations.\n- Consider using a better media player library (e.g. VLC via libVLC or other) if you want more codec/streaming support.\n- Add search/filter by country or genre.\n- Handle invalid or unavailable streams gracefully (timeouts, errors).\n- Package your app with an installer, or publish a portable build.\n\n---\n\nIf you like, I can generate a fully working project zip structure with sample stations and ready to run, or even include fetching station lists from the internet. Would you prefer I do that (give you all files)?"
