### Parse Tiled Map with TiledLib.Net

Source: https://github.com/ragath/tiledlib.net/blob/master/README.md

Demonstrates the basic usage of TiledLib.Net to parse a Tiled map file. It shows how to open a stream, load the map, and iterate through tile layers to access tile data. This example requires the TiledLib NuGet package and standard file I/O operations.

```csharp
using System;
using System.IO;
using System.Linq;
using TiledLib;

// Assuming 'filename' is the path to your Tiled map file.
string filename = "path/to/your/map.tmx"; 

try
{
    using (var stream = File.OpenRead(filename))
    {
        // Load the map, providing a way to resolve tileset sources relative to the map file.
        var map = Map.FromStream(stream, ts => File.OpenRead(Path.Combine(Path.GetDirectoryName(filename), ts.Source)));

        // Iterate through all layers, specifically looking for TileLayers.
        foreach (var layer in map.Layers.OfType<TileLayer>())
        {
            // Iterate through each tile in the layer.
            for (int y = 0, i = 0; y < layer.Height; y++)
                for (int x = 0; x < layer.Width; x++, i++)
                {
                    var gid = layer.data[i]; // Get the global tile ID.
                    if (gid == 0)
                        continue; // Skip empty tiles.

                    // Find the tileset that contains this tile.
                    var tileset = map.Tilesets.Single(ts => gid >= ts.FirstGid && ts.FirstGid + ts.TileCount > gid);
                    // Get the specific tile information from the tileset.
                    var tile = tileset[gid];

                    // Do stuff with the tile, e.g., render it, check its properties, etc.
                    // Console.WriteLine($"Tile at ({x},{y}): GID={gid}, TileName={tile.Name}");
                }
        }
    }
}
catch (FileNotFoundException)
{
    Console.WriteLine($"Error: Map file not found at {filename}");
}
catch (Exception ex)
{
    Console.WriteLine($"An error occurred: {ex.Message}");
}
