Model State Validation in ASP.NET WEBAPI Core

Question

I am trying to use model validation in ASP.NET WEBAPI Core. Below mentioned is the code from my model.

[Range(typeof(decimal), "1.0", "90.1")]
public decimal price{ get; set; }

My understanding is, if I pass any value which is not in between 1.0 - 90.1, the ModelState.Valid should be false.

Here is the url I tried to call the method,

http://localhost:57270/api/testprice?price=132.7492634

Since the value which I have passed greater than 90, I was expecting ModelState.Valid as false. But always the ModelState.Valid is coming as true.

Am I missing anything? Please help?

@FrankNielsen : Thanks for the reply. When we use type in RangeAttribute, we have to mention both min and max value as strings only. — Ane, Mar 03 '18 at 22:03

Try this:

[Range(1.0, 90.1)]
public decimal price{ get; set; }

For the benefit of other users, I am posting the answer to this question.

To get full functionality of data annotations in .net core, we need to add the below line in ConfigureServices function in startup.cs file:

services.AddMvcCore().AddDataAnnotations();

Hope it helps. Have a nice day to all.
