Question

Here是结果的一个例子，（facebook public exmaple）

（/搜索Q =咖啡＆安培;类型=地方＆安培;中心= 37.76，-122.427＆安培;距离= 1000）

我有这个型号：

[DataContract]
public class FBPlaces
{
    [DataMember(Name = "data")]
    public List<Place> Data { get; set; }

    [DataMember(Name = "paging")]
    public Paging Paging { get; set; }
}

[DataContract]
public class Paging
{
    [DataMember(Name = "next")]
    public string Next { get; set; }
}

[DataContract]
public class Place
{
    [DataMember(Name = "location")]
    public List<Location> Locations { get; set; }

    [DataMember(Name = "category")]
    public string Category { get; set; }

    [DataMember(Name = "name")]
    public string Name { get; set; }

    [DataMember(Name = "id")]
    public string ID { get; set; }
}

[DataContract]
public class Location
{
    [DataMember(Name = "street")]
    public string Street { get; set; }

    [DataMember(Name = "city")]
    public string City { get; set; }

    [DataMember(Name = "state")]
    public string State { get; set; }

    //[DataMember(IsRequired = false, Name = "country ")]
    //public string Country { get; set; }

    [DataMember(Name = "zip")]
    public string Zip { get; set; }

    [DataMember(Name = "latitude")]
    public double Latitude { get; set; }

    [DataMember(Name = "longitude")]
    public double Longitude { get; set; }
}

问题是映射“location”数组，我得

System.ArgumentException：为调用方法'Void set_Item（Int32，MyProject.Models.Location）'提供的参数数量不正确

如果我删除地点，一切都很好，我得到了Catergory + Name + Id。（但没有地点）
如何解决？
在我的实例（不同位置查询）中，“country”并不总是显示，我如何处理这类数据？我评论了乡村财产。

Answer 1

位置不是一个阵列。

尝试

[DataContract]
 public class Place
 {
    [DataMember(Name = "location")]
    public Location Locations { get; set; }

    [DataMember(Name = "category")]
    public string Category { get; set; }

    [DataMember(Name = "name")]
    public string Name { get; set; }

    [DataMember(Name = "id")]
    public string ID { get; set; }
}
