Duplicate key

[nukadelic]

Using a dropdown UI i try and load a yaml file each time the value is changing, running in Unity 2019 via simple system IO:

            var fileStream = new FileStream( file.FullName, FileMode.Open, FileAccess.Read);
            using (var streamReader = new StreamReader(fileStream, Encoding.UTF8))
            {
                        var deserializer = new DeserializerBuilder()
                                .WithNamingConvention( new CamelCaseNamingConvention() )
                                .Build();
                            var yaml = new YamlStream();
                           yaml.Load( streamReader );
... 

Here is the error i am getting :

As indicated in the exception message, there must be a duplicate key in your YAML file, on line 26, column 5. If you share your file, I may be able to provide more help.

Thanks for the response, found an alternative way to solve my problem.
I think It was an error on the load level, looks like it wasn't able to handle repeated loading, it could be that my code wasn't disposing the stream properly, but didn't end up finding how to do that on the YamlSteam class. And since the file that needed to be parsed does have a very basic structure, I ended up using the Deserializer only, like so:

var deserializer = new DeserializerBuilder()
    .WithNamingConvention( new CamelCaseNamingConvention() )
    .Build();

Dictionary<string, object> raw = deserializer.Deserialize<Dictionary<string, object>>( streamReader );

string[] categories = raw.Keys.ToArray();

var data = raw.Values.Select( config => ( Dictionary<object, object> ) config ).ToArray();

List<SortedDictionary<string, string>> output = new List<SortedDictionary<string, string>>();

foreach( var d in data )
{
    SortedDictionary<string, string> dict = new SortedDictionary<string, string>();

    foreach( var k in d.Keys ) dict.Add( k.ToString(), d[ k ].ToString() );

    output.Add( dict );
}

return output;

If you want i can try and replicate the problem, its just that I'm using your code in Unity 2019 (.NET 4.x)

In that case it seems to be be a bug. I think I have the necessary information to reproduce it. I'll let you know. Thanks
