Can you try this piece of code?

public class CommonMasterDataResponse
{
    public CommonMasterDataResponse()
    {

    }

    public bool ShouldSerializeDto1()
    {
        return Dto1.Any();
    }

    [XmlElement(IsNullable = true)]
    public List<string> Dto1 { get; set; }
}

But, I think in general this is a bad practice. Try to create separate Dtos and API end points for every DTO. That way you can avoid this situation. It is easy code and maintain. Also, I believe this would be a performance hit in both the server and client.
