从StreamWriter的继承与最小可能的努力 [英] Inheriting from StreamWriter with smallest possible effort

问题描述

我使用的是外部库，它允许使用StreamWriter的记录 - 现在我想基于日志的内容添加一些处理。因为我想，以避免通过日志文件的循环，我想编写从StreamWriter的继承的类。结果
什么是从StreamWriter的继承与方法/构造函数尽可能少的重新实现的最佳途径？

I am using an external library which allows logging using StreamWriter - now I want to add some handling based on the content of the logging. As I want to avoid to loop through the log file, I would like to write a class which inherits from StreamWriter.
What is the best way to inherit from StreamWriter with as few re-implementations of methods/constructors?

推荐答案

我不知道你想做什么，但如果你只是想检查正在写了什么在流，你可以这样做：

I'm not sure of what you want to do exactly, but if you only want to inspect what is being written in the stream, you can do this:

public class CustomStreamWriter : StreamWriter
{
    public CustomStreamWriter(Stream stream)
        : base(stream)
    {}

    public override void Write(string value)
    {
        //Inspect the value and do something

        base.Write(value);
    }
}
