Required attribute for an integer value

Question

I have a viewmodel with an Id property [Required] public int Id { get; set; } But I think this attribute is working only for string properties. When no Id is set, Id has value 0 and the model is valid. How can I enforce that if no value for a int property is set, the model will be invalid ?

Use the Range Attribute. Set minimum to 1 and maximum to int.MaxValue [Range(1, int.MaxValue, ErrorMessage = "Value for {0} must be between {1} and {2}.")]
