Winforms日志记录框架 [英] Winforms logging framework

问题描述

我正在编写WinForms应用程序.我需要将信息记录到文件中.通常，我使用 log4net 进行日志记录，但是由于限制，我无法添加引用.我无法向项目添加外部引用，因为我必须部署单个可执行文件.

I'm writing a WinForms application. I need to log information into a file. Usually I use log4net for logging, but I cannot add the reference, due to a restriction. I cannot add external references to my project, because I must deploy a single executable.

.NET中是否有内置的日志记录框架，因此我可以登录文件而无需添加外部dll?

Is there any built-in logging framework in .NET so I will be able to log into a file without adding an external dll?

P.S:当然，我不想打开一个流并手动编写.

P.S: Of course I don't wanna open a stream and write manually.

推荐答案

是的， System.Diagnostics.TraceListener 类.您需要定义TRACE常数才能使其正常工作，但是可以通过配置app.config来使用许多内置的tracelisteners:

Yes, the System.Diagnostics.TraceListener class. You will need to define the TRACE constant for it to work, but you can use a number of built in tracelisteners, through configuration of your app.config:

• ConsoleTraceListener类
• EventLogTraceListener类
• XmlWriterTraceListener类
• TextWriterTraceListener类

• ConsoleTraceListener Class
• EventLogTraceListener Class
• XmlWriterTraceListener Class
• TextWriterTraceListener Class

如果要写入文件，app.config看起来像这样，您还可以添加很多过滤器:

The app.config looks something like this if you want to write to a file, there are a lot of filters you can also add:

<?xml version="1.0" encoding="utf-8"?>
<configuration>
    <system.diagnostics>
        <trace autoflush="false" indentsize="4">
          <listeners>
            <add name="yourName" type="System.Diagnostics.TextWriterTraceListener" initializeData="c:\mylogfile.txt" />
          </listeners>
        </trace>
    </system.diagnostics>
</configuration>

和用法:

Trace.TraceError("There's been an error captain: {0}", e);
Trace.TraceWarning("The system broke but don't worry.");
Trace.TraceInformation("Starting up the engines.");

如果可以避免的话，我个人不会写入文本文件，事件日志是一个更好的位置，因为您可以对其进行排序，过滤，自动清除日志并且不会遇到文件锁定问题.

Personally I wouldn't write to a text file if you can avoid it, the Event Log is a better location as you can sort, filter, the logs are auto-purged and you don't get file lock up issues.
