C# NLOG：创建同一类的多个实例并将日志写入同一文件

我试图习惯NLOG，发现为同一类的多个实例设置日志文件很困难。每个类都是在不同的线程上创建的。请在下面找到示例代码：

    {
        ILogger mLogger;
        public string Name { get; set; }
        public string SecondName { get; set; }
        private string mFilePath = @"C:\Logs\";
        public test(string name, string secondname)
        {
            var target = new FileTarget(name) { FileName = mFilePath + name + ".txt" };
            var config = new LoggingConfiguration();
            config.AddRule(LogLevel.Info, LogLevel.Info, target);
            LogManager.Configuration = config;
            mLogger = LogManager.GetLogger(name);
            LogManager.ReconfigExistingLoggers();
            mLogger.Info("Hi from :" + name);
        }
    }
    static void Main(string[] args)
        {
            new Thread(new ThreadStart(() => { new test("Stuart", "Broad"); })).Start();
            new Thread(new ThreadStart(() =>
            {
                new test("John", "Smith");
            })).Start();
            new Thread(new ThreadStart(() =>
            {
                new test("Virat", "Kohli");
            })).Start();
            new Thread(new ThreadStart(() =>
            {
                new test("Christiano", "Ronaldo");
            })).Start();

            new Thread(new ThreadStart(() =>
                {
                    new test("Pat", "cummins");
                })).Start();
            Console.Read();
        }

输出为： 2020-03-03 11:36:56.9404 |信息|克里斯蒂亚诺|你好，发件人：克里斯蒂亚诺 2020-03-03 11:36:56.9404 |信息|斯图尔特|你好，发件人：斯图尔特 2020-03-03 11:36:56.9404 |信息|约翰|你好，发件人：约翰 2020-03-03 11:36:56.9404 | INFO | Virat |你好，发件人：Virat 2020-03-03 11:36:56.9404 |信息|帕特|你好，发件人：帕特

仅从一个文件Christiano.txt

有人能帮我配置一下吗

谢谢。

LogManager。配置是一个静态变量。当你分配它时，你会影响到其他人

相反，为每个线程提供一个唯一的记录器。同一文件目标可以处理多个记录器

{
    ILogger mLogger;
    public string Name { get; set; }
    public string SecondName { get; set; }
    public test(string name, string secondname)
    {
        mLogger = LogManager.GetLogger(name);
        mLogger.Info("Hi from :" + name);
    }
}
static void Main(string[] args)
    {
        string mFilePath = @"C:\Logs\";
        var target = new FileTarget(name) { FileName = Path.Combine(mFilePath, "${logger}.txt") };
        var config = new LoggingConfiguration();
        config.AddRule(LogLevel.Info, LogLevel.Info, target);
        LogManager.Configuration = config;

        new Thread(new ThreadStart(() => { new test("Stuart", "Broad"); })).Start();
        new Thread(new ThreadStart(() =>
        {
            new test("John", "Smith");
        })).Start();
        new Thread(new ThreadStart(() =>
        {
            new test("Virat", "Kohli");
        })).Start();
        new Thread(new ThreadStart(() =>
        {
            new test("Christiano", "Ronaldo");
        })).Start();

        new Thread(new ThreadStart(() =>
            {
                new test("Pat", "cummins");
            })).Start();
        Console.Read();
    }

或者，您可以在文件名布局中使用NLog

${threadname}

而不是

${logger}

另一种选择是使用NLog创建作用域，并在文件名布局中使用

${mdlc:TestName}

。这还允许您将初始上下文流到异步任务。
