What does NotFound do?

[Miljankg]

Hello,

The API contains NotFound clause. However, the implementation of it only checks for whether the Key and Input are null. What would the use case for this clause be?

The statement from the tests Guard.Against.NotFound(1, Guid.Empty, "guid"); will not throw, and I was not able to figure out where would I apply such statement.

Thanks in advance.

Hi, there !
♻️ Guard.Against.NotFound( KEY, VALUE, PARAMNAME )

🔑 KEY : This is id of queried object
📓 VALUE: This is input
🖊️ PARAMNAME : This is queried object's name

Example:
int productId = 1;
var product = context.Products.Where(o => o.Id == productId).FirstOrDefault();
Guard.Against.NotFound("id",product,"product"); // throws NotFoundException if product is null

Personally I would use a Result not a guard/exception for this kind of scenario.

Heey ardalis :)

Actually I am using Exception/Filters. GuardClauses is more appropriate.
