ServiceStack验证多个属性

Question

How do I write the validation rule if I want to check if at least one of the properties in the request DTO is not empty?

I can do it individually, but I can't seem to figure out how to combine multiple to do something like - check if at least one of FirstName, LastName and CompanyName has a value.

This is a Fluent Validation question, you can use When() to selectively apply the rule, eg:

RuleFor(x => x.FirstName)
    .NotEmpty()
    .When(x => (x.LastName ?? x.CompanyName).IsNullOrEmpty());
