c# - 使用 Mapsui 显示线串和跟踪点

Question

我的目的是在地图上使用 Mapsui (wpf) 显示 GPS 轨迹和相应的轨迹点。我尝试了以下代码。结果是显示蓝色线串（ok），红色轨迹点（ok），但出于任何原因，您会看到非常大的白色轨迹点，我不希望它们出现在地图上，我不知道在哪里白点是从哪里来的。知道我做错了什么吗？

protected ILayer CreateLineStringLayer(String name, List<GeoWaypoint> geoWaypoints)
 {
     var lineString = new LineString();

     List<Feature> featureList = new List<Feature>();

     IStyle pointStyle = new SymbolStyle()
     {
         SymbolScale = 0.30,            
         Fill = new Brush(Mapsui.Styles.Color.FromString("Red"))
     };

     foreach (var wp in geoWaypoints)
     {
         var point = SphericalMercator.FromLonLat(wp.Longitude, wp.Latitude);
         lineString.Vertices.Add(point);

         var p2 = SphericalMercator.FromLonLat(wp.Longitude, wp.Latitude);
         var pointFeature = new Feature();
         pointFeature.Geometry = p2;
         pointFeature.Styles.Add(pointStyle);
         featureList.Add(pointFeature);
      }
        

     IStyle linestringStyle =  new VectorStyle()
     {
        Fill = null,
        Outline = null,
        Line = { Color = Mapsui.Styles.Color.FromString("Blue"), Width = 4 }
     };

    Feature lineStringFeature = new Feature()
    {
       Geometry = lineString
    };
    lineStringFeature.Styles.Add(linestringStyle);

    featureList.Add(lineStringFeature);
    
    MemoryProvider memoryProvider = new MemoryProvider(featureList);

    return new MemoryLayer
    {
       DataSource = memoryProvider,
       Name = name
    };
}

所以对于所有对答案感兴趣的人

return new MemoryLayer
{
   DataSource = memoryProvider,
   Name = name ,
   Style = null
};

您需要将 Memorylayer 的 Style 值设置为 null
