You need to give more information on what framework you are using on the backend side to interact with the database.
If entity framework has been used, probably the query to get the result from the database has "Include" extension method, that's why it is fetching the foreign data too.
You can create new User like this for given Id
var user = conetxt.Users
.Select(u=> new User{ UserId = u.UserId, UserName = u.UserName, ... })
.SingleOrDefault(u=>u.UserId == id);
If you want have List<User>
var user = conetxt.Users
.Select(u=> new User{ UserId = u.UserId, UserName = u.UserName, ... })
.ToList();
It is suggested to use
DTO
instead of Model for Response You should expose only required properties to the client

I am trying to loop through some JSON to create some variables using a dictionary.
Here are the definitions that I am using:
public class Customfield10002
{
public string name { get; set; }
}
public class Fields
{
public string summary { get; set; }
public List<Customfield10002> customfield_10002 { get; set; }
}
public class Issue
{
public string id { get; set; }
public string key { get; set; }
public Fields fields { get; set; }
}
public class Root
{
public List<Issue> issues { get; set; }
}
The following code validates fine.
Root myDeserializedClass = JsonConvert.DeserializeObject<Root>(response.Content);
foreach (var issue in myDeserializedClass.issues)
{
string id = issue.id.ToString();
string key = issue.key.ToString();
string summary = issue.fields.summary.ToString();
{
But when I include the following string field, it fails validation
string creatoremail = issue.fields.customfield_10002.name.ToString();
The error is:
'List<ITSDWorklogs.Customfield10002' does not contain a definition for 'name' and no extension method 'name' accepting a first argument of type"
'List<ITSDWorklogs.Customfield10002' could be found (are you missing a using directive or an assembly reference?)
How can I access the value from this nested list?
Any help greatly appreciated.

you can use LINQ for enumerate over Customfield10002 list:
var createOrEmail = issue.fields.customfield_10002.Select(c=>c.name).DefaultIfEmpty("").Aggregate((s, s1) => $"{s}, {s1}");
This should work as suggested by #gunr2171
string creatoremail = "";
foreach (var names in issue.fields.customfield_10002)
{
creatoremail = names.name.ToString();
}
or by Sajid
string creatoremail = issue.fields.customfield_10002.FirstOrDefault().name.ToString();

In the json response the property "data" is used as a List and in other places in the Json it is used as a string.. when its used in the List the property has some value when its using as a string the value is coming as null..
How to include both scenario here when I am deserialzing and serializing the json.. without running in to exception A member with the name 'data' already exists. Use the JsonPropertyAttribute to specify another name
public class Example
{
[JsonProperty("data", NullValueHandling = NullValueHandling.Ignore)]
public List<Datum> Data { get; set; }
[JsonProperty("data", NullValueHandling = NullValueHandling.Include)]
public string Data { get; set; }
}
Here is what I tried to use a private property but not able to resolve the issue
[JsonProperty("data", NullValueHandling = NullValueHandling.Ignore)]
public List<Datum> Data { get; set; }
[JsonProperty("data2", NullValueHandling = NullValueHandling.Include)]
private List<Datum> Data2 { set { Data = value; } }
Here is the Json

This question already has an answer here:
Map category parent id self referencing table structure to EF Core entity
(1 answer)
Closed 2 years ago.
I have an issue on cleaning querying my parent child without repeating the children at its own root of the list.
Object
public class Office
{
public int Id { get; set; }
[Required]
public string Name { get; set; }
public bool Inactive { get; set; }
public int? ParentId { get; set; }
[ForeignKey("ParentId")]
public Office Parent { get; set; }
[InverseProperty("Parent")]
public virtual ICollection<Office> Children { get; set; }
}
}
The Query
public async Task<IEnumerable<Office>> GetOffices()
{
return await _context.Offices.Where(os => !os.Inactive)
.Include(o => o.Parent)
.Include(o => o.Children).ToListAsync();
}
And the result
{
"id": 5,
"name": "AA",
"inactive": false,
"parentId": null,
"parent": null,
"children": []
},
{
"id": 10,
"name": "BAA",
"inactive": false,
"parentId": 2,
"parent": {
"id": 2,
"name": "BA",
"inactive": false,
"parentId": null,
"parent": null,
"children": []
},
"children": [
{
"id": 1011,
"name": "BAAA",
"inactive": false,
"parentId": 10,
"children": []
}
]
},
{
"id": 1011,
"name": "BAAA",
"inactive": false,
"parentId": 10,
"parent": {
"id": 10,
"name": "BAA",
"inactive": false,
"parentId": 2,
"parent": {
"id": 2,
"name": "BA",
"inactive": false,
"parentId": null,
"parent": null,
"children": []
},
"children": []
},
"children": []
},
,
{
"id": 2,
"name": "BA",
"inactive": false,
"parentId": null,
"parent": null,
"children": [
{
"id": 10,
"name": "BAA",
"inactive": false,
"parentId": 2,
"children": [
{
"id": 1011,
"name": "BAAA",
"inactive": false,
"parentId": 10,
"children": []
}
]
}
]
}
This also has child objects at the root level so I tried this
public async Task<IEnumerable<Office>> GetOffices()
{
return await _context.Offices.Where(os => !os.Inactive && !os.ParentId.HasValue).Include(o => o.Parent).Include(o => o.Children).ToListAsync();
}
And this is the result of the other query
{
"id": 5,
"name": "AA",
"inactive": false,
"parentId": null,
"parent": null,
"children": []
},
{
"id": 2,
"name": "BA",
"inactive": false,
"parentId": null,
"parent": null,
"children": [
{
"id": 10,
"name": "BAA",
"inactive": false,
"parentId": 2,
"children": null
}
]
}
This leaves out id 1010 BAAA child object. Idealy I would like to have it come out as
{
"id": 5,
"name": "AA",
"inactive": false,
"parentId": null,
"parent": null,
"children": []
},
{
"id": 2,
"name": "BA",
"inactive": false,
"parentId": null,
"parent": null,
"children": [
{
"id": 10,
"name": "BAA",
"inactive": false,
"parentId": 2,
"children": [
{
"id": 1011,
"name": "BAAA",
"inactive": false,
"parentId": 10,
"children": []
}
]
}
]
}
No matter how I stack the query I can't seem to get this to display this way. Is there a way to adjust the query to allow this or an easy post query command to trim only the root level objects that are a child?
If you want limited number of child levels (2 in this example) fetched you can try:
await _context.Offices
.Where(os => !os.Inactive && !os.ParentId.HasValue)
.Include(o => o.Parent)
.Include(o => o.Children)
.ThenInclude(o => o.Children)
.ToListAsync()

I think you should first check whether your string is a valid Json.
You may check below link to convert to class.
How to auto-generate a C# class file from a JSON object string
You're looking for this
Using the dynamic object type. Of course you can do some casting or data mapping later on.
Have a look at JSON.Net. Download the nuget package, than use:
dynamic dyn_json = JsonConvert.DeserializeObject(json);
After that you can iterate through the dynamic object and fill your C# object.

Using json2csharp:
public class Subject
{
public int Id { get; set; }
public string OEPTitle { get; set; }
}
public class RootObject
{
public int Class { get; set; }
public string ClassUrl { get; set; }
public string OEPTitle { get; set; }
public List<Subject> Subject { get; set; }
public bool IsArchived { get; set; }
}
and now, you can use JSON.NET:
List<RootObject> rootObj = JsonConvert.Deserialize<List<RootObject>>(yourJsonHere);
