使用Nest从Elasticsearch Index检索类型名称

Question

This is the code that I'm using to get https://esURL/index-name/_mappings

client.GetMapping<object>(mapping => mapping.Index("index-name").AllTypes())

However, this only returns the properties of the mappings and not the names.

Is there something that I am missing with the code?

I also wanna add that I'm using Nest 2.5.0.

You can get all of the type names in one or all indices in NEST 2.5.0 with

var client = new ElasticClient();

// just change .Index() for .AllIndices() for indices
var mappings = client.GetMapping<object>(m => m.Index("posts").AllTypes());

foreach (var index in mappings.IndexTypeMappings)
{
    foreach (var type in index.Value)
    {
        // do something with type names
        Console.WriteLine($"index: '{index.Key.Name}', type: '{type.Key.Name}'");
    }
}
