C#函数：将程序运行信息写入日志

1.LogManager类

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();
        }
    }
}

2.调用方法

LogManager.WriteProgramLog("日志1", "日志2", "日志3");
