  • Capture variables in anonymous methods

    Time:2019-12-19

      The term “capture variable in anonymous method” may have some advantages. What is “capture variable in anonymous method”? Before the chapter begins, we define a delegation:public delegate void MethodInvoke(); 1. Closures and different types of variables: First of all, you should all know “closure”. Its concept is that a function can interact with the environment to a […]

    In the last article, we wrote some basic things about entrustment. In this article, we talked about other things about entrustment. Example 1 plug in programming According to the understanding of delegates, delegates can pass a method as a parameter. With this feature, we can use delegates to implement plug-in programming. public delegate int Transformer(int […]

  • C-covariance and inversion

    Time:2019-12-3

    Microsoft official overview: In C, covariance and inversion can realize implicit reference conversion of array type, delegate type and generic type parameters. Covariant preserves allocation compatibility, while contravariant preserves allocation compatibility. Covariance: the ability to use a more derived type than the originally specified derived type. Contravariant: able to use less derived types. Official example: […]

  • C × lambda expression

    Time:2019-11-27

    I. definition of lambda expression Lambda expression is actually an anonymous function. Using lambda expression can simplify the amount of code needed in development. Lambda expressions can contain statements and expressions, and can be used to create delegate or expression tree types. Inline expressions with input parameters that can be bound to the delegate or […]

  • Review the delegation and event that you can understand under the object-oriented core

    Time:2019-11-5

      The core of case interpretation is object-oriented. All cases are based on C ා, involving the most frequently concerned issues in our practice: 1. Encapsulation, inheritance and polymorphism; 2. Abstract class and interface; 3. Delegation and event. III. entrustment and events Generally speaking, the purpose of using delegation is to “realize the effect of […]

  • C# delegate

    Delegates in C are similar to pointers to functions in C or C + +.DelegateIs a reference type variable that holds a reference to a method. References can be changed at run time. Delegates are specifically used to implement events and callback methods. All delegates are derived fromSystem.DelegateClass.   For example, Xiaoming asks Xiaozhang to […]
