c# - 什么替代了适用于 Windows 商店应用程序的 SQLServer SQLGeometryBuilder

Question

将 Visual Studio 2008 C# 应用程序移植到 Visual Studio 2013、Windows 8.1 store\phone 应用程序（需要在应用程序中包含一个 DB）。使用什么数据库（用 c# 编码）来替换这段代码......

private static double GetArea(SurveySegment[] segments)
{
  SqlGeometryBuilder builder = new SqlGeometryBuilder();
  builder.SetSrid(0); // Don't need an SRID here
  builder.BeginGeometry(OpenGisGeometryType.Polygon);

  // Walk around the segments
  PointF p = new PointF(0, 0);
  builder.BeginFigure(p.X, p.Y);
  for (int i = 0; i < segments.Length; i++)
  {
    p += segments[i].FromOrigin;
    builder.AddLine(p.X, p.Y);
  }

  // Polygon's end point must be at the origin
  if (p.X != 0 || p.Y != 0)
    builder.AddLine(0, 0);

  builder.EndFigure();
  builder.EndGeometry();

  // Return the area in the units used in the segments
  return builder.ConstructedGeometry.STArea().Value;
    }
