我刚开始使用 Sharpmap 但我遇到了问题。我无法使用这个库在地图上打印点（甚至一个点）。
我没有找到一个很好的例子来做这件事，我的代码也不起作用。它与它应该在的地方（马德里，西班牙）相距甚远。
如果有人知道如何使用它，我将不胜感激。
这是我的代码：
namespace TestsSharpmapForm
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
VectorLayer vlay = new VectorLayer("Spain");
vlay.DataSource = new SharpMap.Data.Providers.ShapeFile(@"ESP_adm_shp\ESP_adm2.shp", true);
VectorLayer vlay2 = new VectorLayer("Points");
Collection<GeoAPI.Geometries.IGeometry> geomColl = new Collection<GeoAPI.Geometries.IGeometry>();
//Get the default geometry factory
GeoAPI.GeometryServiceProvider.Instance = new NetTopologySuite.NtsGeometryServices();
GeoAPI.Geometries.IGeometryFactory gf =
GeoAPI.GeometryServiceProvider.Instance.CreateGeometryFactory();
geomColl.Add(gf.CreatePoint(new GeoAPI.Geometries.Coordinate(40.4177623, -3.6690416)));
vlay2.DataSource = new SharpMap.Data.Providers.GeometryProvider(geomColl);
mapBox1.Map.Layers.Add(vlay);
mapBox1.Map.Layers.Add(vlay2);
//ProjNet.CoordinateSystems.Transformations.CoordinateTransformationFactory ctFact = new ProjNet.CoordinateSystems.Transformations.CoordinateTransformationFactory();
//vlay.CoordinateTransformation = ctFact.CreateFromCoordinateSystems(ProjNet.CoordinateSystems.GeographicCoordinateSystem.WGS84, ProjNet.CoordinateSystems.ProjectedCoordinateSystem.WebMercator);
//vlay.ReverseCoordinateTransformation = ctFact.CreateFromCoordinateSystems(ProjNet.CoordinateSystems.ProjectedCoordinateSystem.WebMercator, ProjNet.CoordinateSystems.GeographicCoordinateSystem.WGS84);
mapBox1.Map.ZoomToExtents();
mapBox1.Refresh();
mapBox1.ActiveTool = SharpMap.Forms.MapBox.Tools.Pan;
Image imgMap = mapBox1.Map.GetMap();
}
private void mapBox1_Click(object sender, EventArgs e)
{
}
}
}
