1. 多線程向同一文件寫入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);} }
