C#实现将程序运行信息写入日志的方法

class LogManager
{
 static object locker = new object();
 /// <summary>
 /// 重要信息写入日志
 /// </summary>
 /// <param name="logs">日志列表，每条日志占一行</param>
 public static void WriteProgramLog(params string[] logs)
 {
  lock (locker)
  {
   string LogAddress = Environment.CurrentDirectory + "\\Log";
   if (!Directory.Exists(LogAddress + "\\PRG"))
   {
    Directory.CreateDirectory(LogAddress + "\\PRG");
   }
   LogAddress = string.Concat(LogAddress, "\\PRG\\",
    DateTime.Now.Year, '-', DateTime.Now.Month, '-',
    DateTime.Now.Day, "_program.log");
   StreamWriter sw = new StreamWriter(LogAddress, true);
   foreach (string log in logs)
   {
    sw.WriteLine(string.Format("[{0}] {1}", DateTime.Now.ToString(), log));
   }
   sw.Close();
  }
 }
}
