String : Immutable reference type
Hello!
I don't understand something in C#, and I would love to have some guidance.
In the following code, the variable storing the string called "status" still has the value "Healthy" when outside the method scope.
Prints :
And I would love to understand why.
If the string status is passed as a reference type in the method "SetHeatlh", it means that "status" called in the method as an argument, is a variable with the address of the string "Healthy" somewhere in the Heap.
When the method says
Should it not mean that a new string with value "Unhealthy" is created on the Heap, and then the variable "status" should store the new address of this new string object in itself as a variable? Why is the address of the status not changed when we go out of the method SetHealth?
I thought any change on an reference type variable inside a method should be saved outside of this method?
Any help gladly appreciated
