The compiler appears to show an error when using a struct/ enum or any other value type as my MVC Model.
CS0037 Cannot convert null to 'MyEnum' because it is a non-nullable value type
I created a new MVC project (in VS 2019), created an enum
public enum MyEnum
{
One,
Two,
Three
}
and put it as model in the "About" view:
Why is that occurring?
The compiler appears to show a error when using a struct / value type as my MVC Model.
As per this link, the model can definitely be either a class or a struct. There are pros and cons, but both are allowed.
So, why are you seeing this error then? The short answer is - this is not a real error. It is a fake error.
Visual Studio sometimes shows fake errors, particularly when the dropdown in Error List is set to Build + Intellisense (rather than Build Only).
My suggestion to you is to switch the dropdown to be Build Only. In my projects, Intellisense gives a number of fake errors hence why I leave it in Build Only mode most of the time.
It occurs in Visual Studio 2017 and 2019. I have not tested it elsewhere.
I had a similar problem passing a decimal model to a view. I suffixed the decimal type with the nullable '?' operator:
@model decimal?
