Asp.NET Core API - Change field names

Question

How can API return customised names?

For example:

<UserInfo>
    <name>aaaaaa</name>
    <endpoints>
        <int>1</int>
        <int>2</int>
    </endpoints>
</UserInfo>

is generated from code

public class UserInfo
{
    public string name;
    public int[] endpoints;
}

I'd like to return this:

<User name="aaaaaa">
    <endpoints>
         <endpoint>1</endpoint>
         <endpoint>2</endpoint>
    </endpoints>
</User>

How can I

Rename UserInfo to User
Define name as attribute
Rename fields in endpoints array to endpoint?

I've tried using [DataContract] and [DataMember], but nothing changed.

EDIT: Method I use to get output:

    // GET api/info
    [HttpGet("info")]
    public IActionResult GetInfo([FromHeader] string auth)
    {
        if (HasAccess(auth, Endpoints.Info))
        {
            return new ObjectResult(Database.GetInfoAboutUser(auth));
        }
        else
        {
            return Unauthorized();
        }
    }

I answered number 1, I could not understand numbers 2 and 3, therefore I could not help. — Mohammed Noureldin

@MohammedNoureldin Thank you! It would be great if you had idea how to do instead of ... <name>aaaa</name> this <User name="aaaaa">...</User>. 3. means, that items in the array are named int now, I want to change their name. — SoptikHa

Please post what code you use to generate that XML, and try my answer for number one and three to be sure that we may get rid of it. — Mohammed Noureldin

I use the asp.net core web api - I just return object from controller and asp serializes it on its own. I'll edit answer and add source code tomorrow, as I don't have access to the source code now. learn.microsoft.com/en-us/aspnet/core/tutorials/… — SoptikHa

You have 3 questions in one question. However:

Number one:

I guess this is what you want:

[XmlType(TypeName = "User")]
public class UserInfo
{
...
}

Number three:

int[] values = { 1, 2, 17, 8 };

XDocument doc = new XDocument();
doc.Add(new XElement("endpoints", values.Select( x=> new XElement("item", x))));
