记录日志，无非就是创建一个日志文件。ublic class CreateLogFiles
{    string sLogFormat = "";
    string sErrorTime = "";
    TStagingApp_Log_SQL _tstagingapplog = null;
    public CreateLogFiles()
    {
        try
        {
            sLogFormat = DateTime.Now.ToShortDateString().ToString() + " " + DateTime.Now.ToLongTimeString().ToString() + " ==> ";            sErrorTime=System.DateTime.Now.ToString("yyyyMMdd");
        }
        catch (Exception ex)
        {
            _tstagingapplog = new TStagingApp_Log_SQL();
            _tstagingapplog.CreatedOn = System.DateTime.Now;
            _tstagingapplog.Notes = ex.Message;
            _tstagingapplog.Save();
 
        }
    }    public void ErrorLog(string sPathName, string sErrMsg)
    {
        string path = sPathName + sErrorTime + ".txt";
        string ServiceName = HttpContext.Current.Server.MachineName;
        string IpAddress = HttpContext.Current.Request.UserHostAddress;
        if (!File.Exists(path))
        {
            try
            {
               
                using (StreamWriter sw = File.CreateText(path))
                {
                   
                    sw.WriteLine("ServiceName:" + ServiceName + "\r\n" + "IPAddress:" + IpAddress + "\r\n" + sLogFormat + "\r\n" + sErrMsg);
                    sw.Flush();
                    sw.Close();
                }
                //StreamWriter sw = new StreamWriter(sPathName + sErrorTime + ".txt", true, System.Text.Encoding.Unicode);//when the property set false,then file data is bestrow.            }
            catch (Exception ex)
            {
                _tstagingapplog = new TStagingApp_Log_SQL();
                _tstagingapplog.CreatedOn = System.DateTime.Now;
                _tstagingapplog.Notes = ex.Message;
                _tstagingapplog.Save();
            }
        }
        else
        {
            try
            {
                using (StreamWriter sw = File.AppendText(path))
                {
                    
                    if ((File.GetAttributes(path) & FileAttributes.ReadOnly) == FileAttributes.ReadOnly)
                        File.SetAttributes(path, FileAttributes.Normal);
                    sw.WriteLine("ServiceName:" + ServiceName + "\r\n" + "IPAddress:" + IpAddress + "\r\n" + sLogFormat +"\r\n"+ sErrMsg);
                    sw.Flush();
                    sw.Close();
                }                //StreamWriter sw = new StreamWriter(sPathName + sErrorTime + ".txt", true, System.Text.Encoding.Unicode);//when the property set false,then file data is bestrow.            }
            catch (Exception ex)
            {
                _tstagingapplog = new TStagingApp_Log_SQL();
                _tstagingapplog.CreatedOn = System.DateTime.Now;
                _tstagingapplog.Notes = ex.Message;
                _tstagingapplog.Save();
            }
        }
    }
