如何在我的C#类模型中定义postgis’geography’类型,以便OrmLite可以轻松地将其传递给
Postgresql,这样我除了将空间数据保存到’geography’列之外还可以运行空间查询？
对于这种情况,最好的图书馆是
NetTopologySuite;
你可以像这样使用;
@H_301_7@protected GisSharpBlog.NetTopologySuite.Geometries.Geometry _geom; public GisSharpBlog.NetTopologySuite.Geometries.Geometry Geom { get { return _geom; } set { _geom = value; } } protected string _geomwkt; public virtual string GeomWKT { get { if (this.Geom != null) return this.Geom.ToText(); else return ""; } set { string wktString = value; if (string.IsNullOrEmpty(wktString)) _geom = null; else { var fact = new GeometryFactory(); var wktreader = new WKTReader(fact); _geom = (Geometry)wktreader.Read(wktString); } } }
