Answer 1

Late to the game, but...

I created a helper method using ModelMetadata like @Daniel mentioned and I thought I'd share it:

public static string GetDisplayName(
      this TModel model
    , Expression> expression)
{
    return ModelMetadata.FromLambdaExpression(
        expression,
        new ViewDataDictionary(model)
        ).DisplayName;
}

Example Usage:

Models:

public class MySubObject
{
    [DisplayName("Sub-Awesome!")]
    public string Sub { get; set; }
}

public class MyObject
{
    [DisplayName("Awesome!")]
    public MySubObject Prop { get; set; }
}

Use:

HelperNamespace.GetDisplayName(Model, m => m.Prop) // "Awesome!"
HelperNamespace.GetDisplayName(Model, m => m.Prop.Sub) // "Sub-Awesome!"
