ASP.NET MVC 错误日志记录_.NET_编程开发_程序员俱乐部

创建一个 BaseController 继承自 Controller 重写基方法，新建的Controller继承BaseController即可。

class="brush:csharp;gutter:true;">    public class BaseController : Controller
    {      
        /// <summary>
        /// 错误页面处理
        /// </summary>
        /// <param name="filterContext"></param>
        protected override void OnException(ExceptionContext filterContext)
        {
            // 记录错误日志
            ErrorLog.Write(filterContext);
        }
    }

创建记录错误日志类

    using System.IO;
    using System.Text;
    using System.Web;
    using System.Web.Mvc;

    /// <summary>
    /// 记录错误日志
    /// </summary>
    public class ErrorLog
    {
        public static void Write(ExceptionContext filterContext)
        {
            var dt = DateTime.Now;
            var logPath = HttpContext.Current.Server.MapPath("/log/" + dt.ToString("yyyy-MM"));
            if (!Directory.Exists(logPath))
            {
                Directory.CreateDirectory(logPath);
            }
            var logFilePath = string.Format("{0}/{1}.txt", logPath, dt.ToString("yyyy-MM-dd"));
            StreamWriter writer = null;
            try
            {
                writer = new StreamWriter(logFilePath, true, Encoding.UTF8);
                writer.WriteLine("------------------------------------------------------------------------------");
                writer.WriteLine("出错时间：" + DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss"));
                writer.WriteLine("错误信息：" + filterContext.Exception.Message);
                writer.WriteLine("Controller：" + filterContext.Controller);
                writer.WriteLine("错误源：" + filterContext.Exception.Source);
                writer.WriteLine("堆栈信息：" + filterContext.Exception.StackTrace);
                writer.WriteLine("------------------------------------------------------------------------------");
            }
            catch
            {
            }
            finally
            {
                if (writer != null)
                {
                    writer.Close();
                }
            }
        }
    }
