我正在接管一个C#项目,在测试时我遇到了错误.错误是无法写入日志文件,因为它正被另一个进程使用.这是代码:

    public void WriteToLog(string msg)
    {
        if (!_LogExists) 
        {
            this.VerifyOrCreateLogFile();  // Creates log file if it does not already exist.
        }

        // do the actual writing on its own thread so execution control can immediately return to the calling routine.
        Thread t = new Thread(new ParameterizedThreadStart(WriteToLog));
        t.Start((object)msg);
    }

    private void WriteToLog(object msg)
    {
        lock (_LogLock)
        {
            string message = msg as string;
            using (StreamWriter sw = File.AppendText(LogFile))
            {
                sw.Write(message);
                sw.Close();
            }
        }
    }

_LogLock定义为类变量:

    private object _LogLock = 0;

根据我的研究以及现在几年来在生产系统中运行良好的事实,我不知道问题可能是什么.锁应该阻止另一个线程尝试写入日志文件. …
