我是一名学生,我实际上正在研究如何使用Monmsvelop库Osmsharp。
我使用以下代码进行测试: protected override void OnCreate(Bundle bundle) { base.OnCreate(bundle);
// Set our view from the "main" layout resource
SetContentView (Resource.Layout.Main);
// create a router from an osm file.
Router router = Router.CreateFrom(new FileInfo("demo.osm"));
// instantiate route end coordinates.
GeoCoordinate location_from = new GeoCoordinate(51.26565,4.7777);
GeoCoordinate location_to = new GeoCoordinate(51.2741,4.79795);
// resolve the end points and link them to the road network.
ResolvedPoint from = router.Resolve(location_from);
ResolvedPoint to = router.Resolve(location_to);
// calculate the route.
OsmSharpRoute route = router.Calculate(from, to);
// save the route as a GPX file.
route.SaveAsGpx(new FileInfo("demo.gpx"));
}
(此代码是来自Osmsharp库的教程中的代码)
我的问题是当我构建项目时,我有这个错误:
System.IO.FileNotFoundException:无法加载程序集'System.Drawing,Version = 4.0.0.0,> Culture = neutral,PublicKeyToken = b03f5f7f11d50a3a'。也许它不存在于> Android配置文件的Mono中?
文件名:'System.Drawing.dll'
经过一番研究,我添加了对'System.Drawing.dll'和'OpenTK.dll'文件的引用。我还在文件的开头添加了“using”但是我有与以前相同的错误,我不明白为什么。
我想知道是否可以在Mono for Android项目中使用Osmsharp库?
答案 0 :(得分:0)
我猜OsmSharp需要System.Drawing.dll,这在Mono for Android中不可用。
