生成Log文件的写法

System.IO.StreamWriter w = new System.IO.StreamWriter(Server.MapPath("~/App_data/xxx.log"), true);
w.WriteLine(DateTime.Now.ToString("dd/MM/yyyy HH:mm:ss") + " IP:" + clientIp + " UserName:" + this.Login1.UserName);
w.Close();

 

 1 using System.IO;
 2 public static void WriteLog(string strLog)
 3 {
 4   string sFilePath="d:\\"+DateTime.Now.ToString("yyyyMM");
 5   string sFileName = "rizhi" + DateTime.Now.ToString("dd") + ".log";
 6   sFileName = sFilePath+ "\\"+sFileName; //文件的绝对路径
 7   if (!Directory.Exists(sFilePath))//验证路径是否存在
 8   {
 9     Directory.CreateDirectory(sFilePath);
10     //不存在则创建
11   }
12   FileStream fs;      
13   StreamWriter sw;
14   if (File.Exists(sFileName))
15   //验证文件是否存在，有则追加，无则创建
16   {
17     fs = new FileStream(sFileName, FileMode.Append, FileAccess.Write);
18   }
19   else
20   {
21     fs = new FileStream(sFileName, FileMode.Create, FileAccess.Write);
22   }
23   sw = new StreamWriter(fs);
24   sw.WriteLine(DateTime.Now.ToString("yyyy-MM-dd HH-mm-ss") + "   ---   " + strLog);
25   sw.Close();
26   fs.Close();    
27 }
