I am trying to deserialize a json string from an api.

All works except for a nested item - Location which always ends up null

This is the string structure:

[
    {
        "CompanyProfile": "<p>A&amp;B Inc etc...</p>",
        "Address": "56 Test Street, Test, UK",
        "Location": {
            "Latitude": 61.52787,
            "Longitude": -4.32095,
            "Zoom": 13,
            "Icon": null,
            "Format": 0,
            "Api": null,
            "SearchTyped": null
        },
        "Id": 1723,
        "Name": "A&B Inc"
    },
        {
        "CompanyProfile": "<p>B&amp;C Inc etc...</p>",
        "Address": "57 Test Street, Test, UK",
        "Location": {
            "Latitude": 61.2122,
            "Longitude": -4.31111,
            "Zoom": 13,
            "Icon": null,
            "Format": 0,
            "Api": null,
            "SearchTyped": null
        },
        "Id": 1723,
        "Name": "B&C Inc"
    },
]

These are the classes to map to:

public class MemberDto
{
    public int Id { get; set; }
    public string? Name { get; set; }
    public string? CompanyProfile { get; set; }
    public string? Address { get; set; }
    public Location? Location { get; internal set; }
}

public class Location
{
    public decimal Latitude { get; set; }
    public decimal Longitude { get; set; }
}

This is the deserialize code:

var result = await response.Content.ReadAsStringAsync();
var members = JsonConvert.DeserializeObject<List<MemberDto>>(result);

I know I can use ReadFromJsonAsync<List<MemberDto>>() as well but using ReadFromString so I can check the json before deserializing. Anyway the result is exactly the same for ReadFromJsonAsync.

Everything except Location is deserialized successfully

Anyone know what the issue is?

CodePudding user response：

Remove the internal access modifier in the setter of Location.

public Location? Location { get; set; }
