How to specify a min but no max decimal using the range data annotation attribute?

Question

I would like to specify that a decimal field for a price must be >= 0 but I don\'t really want to impose a max value.

Here\'s what I have so far...I\'m not sure what the

Answer 1

using Range with

[Range(typeof(Decimal), "0", "9999", ErrorMessage = "{0} must be a decimal/number between {1} and {2}.")]

[Range(typeof(Decimal),"0.0", "1000000000000000000"]

Hope it will help

Answer 2

If you are concerned about the string looking nice you could do this:

    [Range(0, Double.PositiveInfinity)]

This will have a default error message of:

The field SuchAndSuch must be between 0 and Infinity.

Answer 3

I was going to try something like this:

[Range(typeof(decimal), ((double)0).ToString(), ((double)decimal.MaxValue).ToString(), ErrorMessage = "Amount must be greater than or equal to zero.")]

The problem with doing this, though, is that the compiler wants a constant expression, which disallows ((double)0).ToString(). The compiler will take

[Range(0d, (double)decimal.MaxValue, ErrorMessage = "Amount must be greater than zero.")]

Answer 4

If you're working with prices, I'm sure you can safely assume nothing will cost more than 1 trillion dollars.

I'd use:

[Range(0.0, 1000000000000)]

Or if you really need it, just paste in the value of Decimal.MaxValue (without the commas): 79,228,162,514,264,337,593,543,950,335

Either one of these will work well if you're not from Zimbabwe.
