如何反序列化嵌套的JSON数组？

Question

我正在尝试反序列化GeoJson，以便我可以将其分解并存储在Db中。当我尝试反序列化它时，coordinates的反序列化失败了。

我使用以下类来表示几何：

public class GeoJsonGeometry {
    public string type { get; set; }
    public string[, ,] coordinates { get; set; }
}

"geometry": { "type": "Polygon", "coordinates": [ [ [ -85.388717, 33.913044 ], [ -85.380885, 33.873508 ], [ -85.379455, 33.866291 ], [ -85.377426, 33.856047 ], [ -85.376403, 33.850656 ], [ -85.364595, 33.788446 ], [ -85.361844, 33.773951 ], [ -85.360491, 33.767958 ], [ -85.357402, 33.750104 ], [ -85.355252, 33.739245 ], [ -85.344054, 33.682684 ], [ -85.342722, 33.675953 ], [ -85.323792, 33.580339 ], [ -85.315340, 33.537646 ], [ -85.314994, 33.535898 ], [ -85.314843, 33.534951 ], [ -85.314091, 33.530218 ], [ -85.313999, 33.529807 ], [ -85.304439, 33.482884 ], [ -85.308211, 33.481579 ], [ -85.309250, 33.483137 ], [ -85.314852, 33.487603 ],...]]]

我已经尝试了double [,,]，但它也没有用。

我很困惑，因为它看起来应该很好地序列化它的嵌套数组，但事实并非如此。任何帮助，将不胜感激。

我还尝试了List<List<List<double>>>和double[][][]，但它总是失败。

您的Geometry对象应为

public class Geometry
{
    public string type { get; set; }
    public List<List<List<double>>> coordinates { get; set; }
}

修改

var obj = JsonConvert.DeserializeObject<RootObject>(json);


public class Geometry
{
    public string type { get; set; }
    public List<List<List<double>>> coordinates { get; set; }
}

public class RootObject
{
    public Geometry geometry { get; set; }
}

JSON不支持多维arrrays。

这是一组数组数组：double[][][]。
