写在ASP.NET中的日志文件 [英] Write to a log file in ASP.NET

问题描述

我使用File.AppendAllText方法写入事件数据在一个asp.net HttpHandler的日志文件。我关心的是，当同时收到多个请求，会发生什么。是否AppendAllText锁定它写入文件？

I am writing event data to a log file in an asp.net httphandler by using the File.AppendAllText method. I am concerned with what will happen when multiple requests are received simultaneously. Does AppendAllText lock the file it's writing to?

推荐答案

没有，你应该有一个静态锁对象守着日志文件的写入，例如

no, you should have a static lock object guarding the log-file write, e.g.

public static object LockingTarget = new object();

public void LogToFile(string msg)
{
    lock(LockingTarget)
    {
        //append to file here as fast as possible
    }
}
