The default value to a property ins't really default

I was trying to do a simple and easy-to-use validation for a class today, and I came across this situation

First I wrote this class using a property and added there a default value like this public int Age { get; set; } = 18, and I thought already that this property has a default value, and if I compare this instance with default(T), will I have a simple validator?

And the answer is NO, I know there are some great projects like Flunt or FluentValidation, but I thought of a simple comparator with the default values, and what I've seen is that actually the =18 is actually just an assignment that occurs during the moment the class is instantiated, but that when declaring the default(T) value it doesn't actually do any attribution declaring only as null.

As we can see in previous image, the default(T) return a null value for a reference type like my example class and for a value type this will return 0 value.

For finish this is definition from (docs) [https://docs.microsoft.com/en-us/dotnet/csharp/properties] for an default property.

if by chance you know any easy way to validate please contribute to the comments below, thanks for reading.

C# lambda vs foreach readability.

Hey guys, recently a receive an feedback that i need to change my code, turn an lambda expression into a foreach loop because its more adherent to clean code, i create this example to explain.

The both versions give me same results, but in my opinion this lambda expression is easy to understand, and easy to write and maintain, and i like to use that.

i receive an recommendation to change that to a for-each loop, like this, to be more clean code adherent.

I really want see other people opinions and arguments about this, and i like lambda expression for me they are very powerful and easy to use.
