Fluent Validation, different validation for each item in a list in Asp.NET Core

Question

I´ve been trying to find a way to validate items inside a list, each with different validation rules. I came upon Fluent validation which is a great library but I can´t seem

You are approaching the validation from the wrong perspective. Instead of creating validation conditions inside your collection container class, just create another validator specific for your Property class, and then use that inside your ADPropertiesValidator:

public class ADPropertyValidator : AbstractValidator<Property>
{
    public ADPropertyValidator()
    {
        When(p => p.Name.Equals("sAMAccountName"), () =>
        {
            RuleFor(p => p.input)
                .NotEmpty()
                .MyOtherValidationRule();
        });

        When(p => p.Name.Equals("anotherName"), () =>
        {
            RuleFor(p => p.input)
                .NotEmpty()
                .HereItIsAnotherValidationRule();
        });
    }
}

public class ADPropertiesValidator : AbstractValidator<EditPersonalInfoViewModel>
{
    public ADPropertiesValidator()
    {
        RuleForEach(vm => vm.UserPropertyList)
            .SetValidator(new ADPropertyValidator());
    }
}
