I have developed a .NET 7 web api with an endpoint that fetches user data.
public class User
{
public Guid? Id { get; set; }
public String? Name { get; set; }
public Int32? Age { get; set; }
public String? HairColor { get; set; }
}
When the "Name" parameter is included in the query string under Select, only the Name property is fetched from the database and returned with the Ok(users); response. For example:
[
{
"id": null,
"name": "Test1",
"age": null,
"hairColor": null
},
{
"id": null,
"name": "Test2",
"age": null,
"hairColor": null
},
{
"id": null,
"name": "Test3",
"age": null,
"hairColor": null,
}
]
To optimize the package size, I want to modify it to return only:
[
{
"name": "Test1"
},
{
"name": "Test2"
},
{
"name": "Test3"
}
]
However, if no parameters are specified in the Select query, all properties should be populated and returned, even if they are null or default values. How can I dynamically configure
JsonSerializerOptions options = new()
{
DefaultIgnoreCondition = JsonIgnoreCondition.WhenWritingDefault
};
So that when the Select parameter is provided, the serialization process for Ok(users) skips any properties that are null or default values, but includes all properties otherwise?
