IFluentGraphValidator

IFluentGraphValidator allows to recursively validate model graph.

public class MyService {
    
    private IFluentGraphValidator _fluentGraphValidator;

    public MyService(IFluentGraphValidator fluentGraphValidator) {
        _fluentGraphValidator = fluentGraphValidator;
    }
    
    public async Task SaveDataAsync(MyData data, CancellationToken cancellationToken = default) {
        var result = await _fluentGraphValidator.TryValidateModelAsync(data, cancellationToken);
        if(result.IsValid) {
            // validation was successfull
        }
        else {
            // every model validation results is in result.Results
        }
    }
}

public class MyData {
    public string Name { get; set; } = "";
    public MySubData? SubData { get; set; }
    public List<MySubData> SubDataList { get; set; } = new List<MySubData>();
}

public class MySubData {
    public string SubName { get; set; } = "";
}

public class MyDataValidator : AbstractValidator<MyData> {
    public MyDataValidator() {
        RuleFor(x => x.Name).NotEmpty();
    }
}

public class MySubDataValidator : AbstractValidator<MySubData> {
    public MySubDataValidator() {
        RuleFor(x => x.SubName).NotEmpty();
    }
}
