Learn about generic classes used in collections like linked lists, hash tables, stacks, queues, and trees.
In C#, nested types can be defined in generic classes just like they would be in non-generic classes. For example: class G<T> { public class NestedC { } public enum NestedEnum { A, B } } Inside the nested type NestedC, we can still use type parameter T, which was "declared" ...

1. 协变逆变:泛型委托,泛型接口,前面又加上了 in , out ,所以称为了泛型的协变,逆变,让我们继续往下面看例子 //定义了一个动物的实体类publicclassAnimal {publicintId {get;set; } }//定义了一个猫猫的实体类,继承Animal类publicclassCat:Animal ...
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 ...
The meaning of GENERIC is relating to or characteristic of a whole group or class : general. How to use generic in a sentence.

In this respect, it is similar to the SortedList<TKey,TValue> generic class. The two classes have similar object models, and both have O(log n) retrieval. Where the two classes differ is in memory use and speed of insertion and removal:...
