//写日志
public static void WriteLog(string Msg)
{
    string sDirPath = ".\\log\\";
    CreateDir(sDirPath);
    string sFilePath = sDirPath + DateTime.Now.ToString("yyyy-MM-dd") + ".log";
    try
    {
       using (StreamWriter sw = File.AppendText(sFilePath))
       {
          sw.Write(DateTime.Now.ToString("HH-mm-ss") + ":" + Msg + "\r\n");
          sw.Flush();
          sw.Dispose();
        }
     }
    catch { }
}

//创建日志所在目录
public static void CreateDir(string dirPath)
{
    if (!Directory.Exists(dirPath))
    {
       try
       {
         Directory.CreateDirectory(dirPath);
       }
       catch { }
