博客介绍了C#中析构函数的相关知识。析构函数用于实现销毁类实例所需的操作，它不能有参数、访问修饰符，也不能被显式调用，会在垃圾回收时自动调用。还给出了一个带析构函数的Point类示例。

A destructor is a member that implements the actions required to destruct an
instance of a class. Destructors
cannot have parameters, they cannot have accessibility modifiers, and they
cannot be called explicitly. The
destructor for an instance is called automatically during garbage
collection.
C# LANGUAGE SPECIFICATION

The example
using System;
class Point
{
public double x, y;
public Point(double x, double y) {
this.x = x;
this.y = y;
}
~Point() {
Console.WriteLine("Destructed {0}", this);
}
public override string ToString() {
return string.Format("({0}, {1})", x, y);
}
}
shows a Point class with a destructor.
