PostUrlEncodedAsync with complex object - flurl

Question

Hi I'm trying to post an object that is like :
public class myobj
{
public string name {get;set;}
public myEntity myentity {get;set;}
public mySecondEntity mySecondEntity {get;set;}
}
public class myEntity {get;set;}
{
public string name {get;set;}
public string description {get;set;}
}
public class mySecondEntity {get;set;}
{
public string name {get;set;}
public string description {get;set;}
}
When I use generate a new object of myObj and use PostUrlEncodedAsync it is posting it as :
name : "myname",
myentity : "detex.Models.DTO.myEntity",
mysecondentity : "detex.Models.DTO.mySecondEntity
Not sure what my namespace/class is doing in those fields. I'm posting this as
await "myurl.com".PostUrlEncodedAsync(_model).

Flurl assumes that objects passed to PostUrlEncodedAsync represent simple name/value pairs. It simply does a ToString on your values, which is why you're getting detex.Models.DTO.myEntity. Do you want those values serialized to JSON? If so you'll need to do that yourself:
"myurl.com".PostUrlEncodedAsync(new {
name = _model.name,
myentity = JsonConvert.SerializeObject(_model.myentity),
mysecondentity = JsonConvert.SerializeObject(_model.mySecondEntity)
});
Posting complex objects as URL-encoded is not typical, which is why serializing those values is not built into Flurl.
