This article mainly explains "how to use the destructor in C#". The content of the explanation in this article is simple and clear, and it is easy to learn and understand. let's go deep into the train of thought of Xiaobian. Let's study and learn how to use the destructor in C#.
Destructor in C #
The destructor of a class is a special member function of the class, which is executed when the object of the class is out of scope.
The name of the destructor is prefixed with a wavy (~) in front of the name of the class, which returns no value and no parameters.
Destructors are used to release resources before ending the program (such as closing files, freeing memory, and so on). Destructors cannot be inherited or overloaded.
The following example illustrates the concept of a destructor:
Using System
Namespace LineApplication
{
Class Line
{
Length of private double length; / / Lin
Public Line () / / constructor
{
Console.WriteLine ("object created")
}
~ Line () / / destructor
{
Console.WriteLine (object deleted)
}
Public void setLength (double len)
{
Length = len
}
Public double getLength ()
{
Return length
}
Static void Main (string [] args)
{
Line line = new Line ()
/ / set the length of the line
Line.setLength (6.0)
Console.WriteLine ("Line length: {0}", line.getLength ())
}
}
}
