In C#, objects are always passed by reference, which means that the reference to the object is passed, not the object itself. This is because objects in C# are managed by the garbage collector, which means that they are automatically freed from memory when they are no longer needed.
When you pass an object by reference, the reference is copied to the method parameter. This means that any changes made to the parameter within the method will be reflected in the original object.
Can I create a new value type?
No, you cannot create a new value type in C#. Value types are a fundamental type in C#, and they are defined by the language itself. You can, however, create new reference types, which are classes or structs that you define yourself.
Value type and garbage collection
When a value type is no longer referenced, it is eligible for garbage collection. This means that the garbage collector may reclaim the memory that was used to store the value type.
The garbage collector runs periodically, and it identifies objects that are no longer needed and reclaims their memory. This helps to prevent memory leaks, which are situations in which memory is allocated but not used, and it can eventually lead to out-of-memory exceptions.
When value type released from memory?
A value type is released from memory when it is no longer referenced and when the garbage collector runs and reclaims the memory that was used to store the value type.
Here are some specific examples of when a value type may be released from memory:
When a variable that references the value type goes out of scope.
When the value type is assigned to a new variable.
When the value type is passed by value to a method.
The garbage collector may also release a value type from memory if it needs the memory to store other objects. However, the garbage collector will not release a value type from memory if it is still being referenced.
