WebApi treating integers values in JSON as true - json

Question

I have a .net core WebApi and swagger to test the API. Now my problem is when I specify numbers for a boolean field in my JSON data for a POST request, in my controller method it is treating as True, which I don't want
Here is my model:
{
public bool Field1 { get; set; }
public bool Field2 { get; set; }
}
{
field1: 2
field2: true
}
And this is how I see the values in the controller
{
field1: true
field2: true
}
Here I don't want integer 2 for field1 to be treated as true and instead, the request should fail
Any recommendations or suggestions will be appreciated.

If you want the request to fail, you will have create a custom set method for the boolean properties and throw an exception as per the failure observed. Something like below:
private bool _field1;
public bool Field1
{
get
{
return _field1;
}
set
{
if(value.GetType() == typeof(bool))
{
_field1 = value;
}
else
{
throw new ArgumentException("Value "+value+" is not of valid type."); // type of exception can be as per the failure observed
}
}
}
Now, within the action method, you should check for ModelState errors. For that you can do:
public IHttpActionResult SomeAction([FromBody] RequestModel request)
{
if(!ModelState.IsValid)
{
foreach (var modelState in ModelState.Values)
{
foreach (var error in modelState.Errors)
{
//collate the errors and send appropriate response back
}
}
}
else
{
// do your usual logic
}
}
You will be getting the exception in a format like:
Exception = {System.ArgumentException: Value 1 is not of
valid type .......
Hope this helps.
