废话不多说，直接上代码：

很简单：将类复制到项目中，最后在配置文件上配置一下：logUrl即可。默认保存在：项目/temp/log

/// <summary>
  /// 日志类
  /// </summary>
  /// <remarks>Creator: v-lxh CreateTime: 2016/7/26 11:18:09</remarks>
  /// <Description></Description>
  public class Log
  {
    /// <summary>
    /// 写入日志.
    /// </summary>
    /// <param name="strList">The STR list.</param>
    /// <remarks>Creator: v-lxh CreateTime: 2016/7/26 11:18:09</remarks>
    /// <Description></Description>
    public static void WriteLog(params object[] strList)
    {
      //判断是否开启日志模式
      //if (!LogModel) return;
      if (strList.Count() == 0) return;
      //日志文件路径
      string strDicPath = "";
      try
      {
        strDicPath = HttpContext.Current.Server.MapPath("~/temp/log/");
        if (strDicPath == null || strDicPath == "")
        {
          strDicPath = System.Configuration.ConfigurationManager.AppSettings["logUrl"] + "/temp/log/";
        }
      }
      catch (Exception e)
      {
        strDicPath = System.Configuration.ConfigurationManager.AppSettings["logUrl"] + "/temp/log/";
      }
      string strPath = strDicPath + string.Format("{0:yyyy年-MM月-dd日}", DateTime.Now) + "日志记录.txt";
      if (!Directory.Exists(strDicPath))
      {
        Directory.CreateDirectory(strDicPath);
      }
      if (!File.Exists(strPath))
      {
        using (FileStream fs = File.Create(strPath)) { }
      }
      string str = File.ReadAllText(strPath);
      StringBuilder sb = new StringBuilder();
      foreach (var item in strList)
      {
        sb.Append("\r\n" + DateTime.Now.ToString() + "-----" + item + "");
      }
      File.WriteAllText(strPath, sb.ToString() + "\r\n-----z-----\r\n" + str);
    }
