  • C# -- 多线程向同一文件写入

    1. 多线程向同一文件写入Log.

    public delegate void AsyncLog(string str1, string str2);

    private
    void Test() { Console.WriteLine("Test Start..."); for (int i = 0; i < 100; i++) { AsyncLog asyLog1 = new AsyncLog(WriteLog); asyLog1.BeginInvoke("EventActionA" + i.ToString(), "EventContentA" + i.ToString(), null, null); AsyncLog asyLog2 = new AsyncLog(WriteLog); asyLog2.BeginInvoke("EventActionB" + i.ToString(), "EventContentB" + i.ToString(), null, null); AsyncLog asyLog3 = new AsyncLog(WriteLog); asyLog3.BeginInvoke("EventActionC" + i.ToString(), "EventContentC" + i.ToString(), null, null); } Console.WriteLine("Test End..."); }
    public static object lockObject = new object();

    private
    void WriteLog(string strEventType, string strEventContent) { lock (lockObject) { Console.WriteLine("Write Log start... ThreadID:{0}", Thread.CurrentThread.ManagedThreadId); string strLogPath = string.Format("D:\Log\Log{0}.log", DateTime.Now.ToString("yyyy-MM-dd")); if (!File.Exists(strLogPath)) { File.Create(strLogPath).Close(); } FileStream fs = new FileStream(strLogPath, FileMode.Append, FileAccess.Write); StreamWriter sw = new StreamWriter(fs, Encoding.UTF8); sw.WriteLine(string.Format("{0} {1}", strEventType, strEventContent)); sw.Close(); fs.Close(); Console.WriteLine("Write Log End ThreadID:{0}", Thread.CurrentThread.ManagedThreadId); } }
