写Log日志的方法 减少插件引用

 1 public class Log

 7 public static void WriteLog(string Message)

11 string path = System.Windows.Forms.Application.StartupPath;
12 DateTime dt = DateTime.Now;
13 string str = Message;
14 if (!Directory.Exists(path + @"ErrLog"))
15 Directory.CreateDirectory(path + @"ErrLog");
16 using (var sw = new StreamWriter(path + @"ErrLog" + (dt.Year + "-" + dt.Month + "-" + dt.Day).ToString() + "_InfoLog.log", true))
17 {
18 sw.WriteLine(dt.ToString() + "---------------------------------------------------------");
