2.日志工具类:
using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.Mvc; using System.Configuration; using System.IO; namespace Arise.Common { public static class LogHelper { public static string RecordError(Exception exception) { string Url = HttpContext.Current.Request.RawUrl;//错误发生地址 string errorMessage = Utility.GetFinnalExceptionMessage(exception); try { string path = ConfigurationManager.AppSettings["TempFilePath"].ToString().Trim(); string year = DateTime.Now.ToString("dd/MM/yyyy").Substring(6, 4); string month = DateTime.Now.ToString("dd/MM/yyyy").Substring(3, 2); string day = DateTime.Now.ToString("dd/MM/yyyy").Substring(0, 2); path += @"ErrorLog\" + year + month; if (!Directory.Exists(path)) //如果文件夹不存在,则创建文件夹(每个月一个文件夹) { Directory.CreateDirectory(path); } string fileName = @"\ErrorLog" + year + month + day + ".txt"; path += fileName; if (!File.Exists(path)) //如果文件不存在,则创建文件(每天一个文件) { File.Create(path).Close(); } StreamWriter writer = new StreamWriter(path, true); String date = DateTime.Now.ToString(); writer.WriteLine("\r\n" + date); writer.WriteLine("Message: "); writer.WriteLine("\t" + errorMessage); writer.Close(); return errorMessage; } catch (Exception) { throw new Exception(errorMessage); } } public static string GetFinnalExceptionMessage(Exception exception) { if (exception.InnerException != null) { return GetFinnalExceptionMessage(exception.InnerException); } return exception.Message; } } }
3.UserMessageShow:(常用的信息,有效的避免了在代码中硬编码)
using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks; namespace Arise.Common { public static class UserMessageShow { public static string ErrorPassword = "Your Password OR UserName is Error!"; public static string ErrorLogin = "Your have alreadly Login System!"; } }
