Bind method to delegate Do you feel like waking up? So, are you wondering: In the above example, I don't have to assign a value to the name parameter directly in the GreetPeople () method. I can use the variable like this: Static void Main (string []

/*************************************** **************************************** ********************************** DelegateIs a type of reference method. Once a method is assigned to the Delegate, the delegate has the same behavior as the delegate.

// Delegate a type definition keyword to define an abstract method.// Instance pointer needs to be passed in the Process of instantiating this type.// The result of Instantiation is to get a method pointer. // The abstract method is used to define

[IT168]Delegation and events are widely used in. Net Framework. However, it is not easy for many people who have been in contact with C # for a long time to better understand delegation and events. They are like a hacker. People who have passed the

The delegate is a function pointer to the function, and is type-safe. One of the useful operations that can be performed using a delegate is to implement callback. Callback is the method used to pass in a function. This method is called when the

Let's use an example to illustrate it. It is better to understand it. It is to open the main form, and the datagridview loads some data. Then, in the opened subform, we enter some conditions so that the data in the main form can be dynamically

Generic delegation is actually a pre-defined Delegate of the. NET Framework, which basically covers all commonly used delegates. Therefore, you do not need to re-declare them.   Simple. Let's look at the following simple example: Code highlighting

Let's look at a simple example. IEnumerable a = new List {"a", "B "}; IEnumerable B =; This is not allowed in versions earlier than 4.0. Although the string is inherited from the object, there is no inheritance relationship between IEnumerable

  Differences between event and delegateFirst, by adding the event keyword, the compiler will automatically generate a private field (delegate related to this event) for the event during compilation and two accessors, that is, the add accessors

Classes are allocated by reference types on the stack. the instance of the class is assigned only by copying the reference, all pointing to the memory allocated by the same actual object. Class constructor and destructor Class can be inherited and

1. Delegation Overview The delegate is a newly added type in C #. You can think of it as a Type similar to the Class. It is similar to the Class used. When using a delegate, two steps are required, first, you need to define a delegate, just like
