我无法弄清楚如何将此集合写入文件。我有以下课程
public static class GeoPolyLines
{
public static ObservableCollection<Connections> connections = new ObservableCollection<Connections>();
}
public class Connections
{
public IEnumerable<IEnumerable<Point>> Points { get; set; }
public Connections(Point p1, Point p2)
{
Points = new List<List<Point>>
{
new List<Point>
{
p1, p2
}
};
}
}
然后是一堆这样的事情:
GeoPolyLines.connections.Add(new Connections(new Point(GeoLocations.locations[0].Longitude, GeoLocations.locations[0].Latitude), new Point(GeoLocations.locations[1].Longitude, GeoLocations.locations[1].Latitude)));
所以 GeoPolyLines.connections 最终会有一堆不同的位置,然后我想写出一个 .txt 文件,以便在需要时保存和重新加载。但我不知道该怎么做。我有这样的事情:
using (StreamWriter sw = new StreamWriter(filename))
{
var enumerator = GeoPolyLines.connections.GetEnumerator();
while (enumerator.MoveNext())
{
}
sw.Close();
}
