要增加你的设计模式的理解的一种方法是，以发现如何图案在.NET框架中使用。

One way to increase your understanding of design patterns is to discover how patterns are used in the .NET framework.

你有没有发现，设计模式任何的例子在.NET框架？在你的答案请给​​图案的简短说明它是如何使用的框架，例如。

Have you found any examples of design patterns in the .NET framework? In your answer please give a short description of the pattern, and example of how it is used in the framework.

示例答案：

战略设计模式脱钩从使用它的算法封装到一个单独的类的类的算法。这允许算法切换

The Strategy Design Pattern decouples an algorithm from the class that uses it by encapsulating the algorithm into a separate class. This allows for switching of algorithms.

List类的排序方法是策略模式的一个例子。

The Sort method of the List class is an example of the Strategy pattern.

public void Sort(IComparer<T> comparer)

通过接受一个的Icomparable接口类的用户可以在运行时切换排序算法。

By accepting an IComparer interface, users of the class can switch the sorting algorithm at runtime.

推荐答案

在装饰图案是用在Stream类：

The Decorator Pattern is used on the Stream classes:

的System.IO.Stream System.IO.BufferedStream System.IO.FileStream System.IO.MemoryStream System.Net.Sockets.NetworkStream System.Security.Cryptography.CryptoStream System.IO.Stream System.IO.BufferedStream System.IO.FileStream System.IO.MemoryStream System.Net.Sockets.NetworkStream System.Security.Cryptography.CryptoStream

该子类装饰流，因为他们继承它，而且他们还含有流的，它被设置在构造函数中的一个实例。

The subclasses decorate Stream because they inherit from it, and they also contain an instance of Stream that is set up in the constructor.
