Serializer doesn't emit a tag with type about yamldotnet HOT 9 CLOSED

Hi,

You need to use the "Roundtrip" option when serializing if you want the tag
to be emitted.

Hi,
Not sure I'm using the library correctly, but when trying to serialize a
simple class like this:

namespace TestYamlDotNet
{
public class Fruit
{
public string Name { get; set; }
}

class Program
{
    static void Main(string[] args)
    {
        var serializer = new Serializer(SerializationOptions.Roundtrip);
        var orange = new Fruit() { Name = "Orange" };
        serializer.Serialize(Console.Out, orange);
    }
}

It is outputing only the Name: Orange property instead of outputing
something like:

!TestYamlDotNet.Fruit
Name: Orange

Is this a correct behavior? I don't see how I can deserialize a node that
doesn't output any tag information.

This is what I have used in the samples above, but I don't get any !TestYamlDotNet.Fruit. I'm using latest git.

Hm, it seems that this is not really handled by current code. Wondering if this part of the code has been really used so far? How are you using YamlDotNet for serializing a complex graph of C# objects to YAML?

I just made a dirty fix to spot where the problem is. TypeAssigningEventEmitter.cs seems to only handle scalars but not mapping nor sequences. I will have to add support for all other cases (sequences, arrays, Dictionary<,>, ICollection<>...etc.)

Edit: Ough, just noticed that YamlDotNet is using tabs instead of spaces, first time discovering that a C# project is using tabs instead of spaces (in VisualStudio it is default to spaces). I will try to keep tabs in my fork

Very interesting because right now you can't roundtrip with properties with an abstract type or interface type, and it would be possible just adding the concrete type tag for those cases.

@icalvo, please take a look at the discussion at #26. There is some work waiting to be merged that would take care of this issue.

@xoofx Is it possible to turn off the tags in your fork? I'd like to get clean Yaml.

@vasily-kirichenko you can turn-off them using latest version of SharpYaml (SerializerSettings.EmitTags = false). Please report issue/usage pb directly on SharpYaml instead of this old discussion, thanks.

@xoofx OK, I'll try that setting. What about your fork - I cannot find any way to add an issue there. The "Issues" link is absent.

@vasily-kirichenko, oops sorry, issues should be opened now
