You stillcan’tsafely useMarshal.SizeOf<T>whenTis an ‘unmanaged’ type. Even though the documentation forMarhal.SizeOf<T>states that the method “Returns the size of an unmanaged type in bytes.”, it is not quite true today. Any enum is considered to be an unmanaged type but trying t...
Generics make it possible to design classes and methods that defer the specification of one or more type parameters until you use the class or method in your code. For example, by using a generic type parameter T, you can write a single class that other client code can use without ...

Learn about generic classes used in collections like linked lists, hash tables, stacks, queues, and trees.
{ Node current = head;while(current !=null) {yieldreturncurrent.Data; current = current.Next; } }// IEnumerable<T> inherits from IEnumerable, therefore this class// must implement both the generic and non-generic versions of// GetEnumerator. In most cases, the non-generic method can// ...

An interface that has a contravariant type parameter allows its methods to accept arguments of less derived types than those specified by the interface type parameter. For example, in theIComparer<T>interface, type T is contravariant, you can assign an object of theIComparer<Person>type to an...

When the go command sees an import of a package with internal in its path, it verifies that the package doing the import is within the tree rooted at the parent of the internal directory. For example, a package .../a/b/c/internal/d/e/f can be imported only by code in the director...
