在树林里,许多的小鸟在自由自在欢乐地飞翔着,高兴起来,便唱出清脆悦耳的曲子,和煦的春风吹拂着小河,河面上波光粼粼。我忽然被一阵悦耳、动听的笛声所牵动,放眼望去,一群顽皮的小孩子正用垂柳的茎做柳笛呢!他们吹出了心里的幸福和快乐。
1.首先常见保存异常的类(就是将异常信息写入到文件中去)
public class LogManager
{
private string logFilePath = string.Empty;
public LogManager(string logFilePath)
{
this.logFilePath = logFilePath;
FileInfo file = new FileInfo(logFilePath);
if (!file.Exists)
{
file.Create().Close();
}
}
public void SaveLog(string message, DateTime writerTime)
{
string log = writerTime.ToString() + ":" + message;
StreamWriter sw = new StreamWriter(logFilePath, true);
sw.WriteLine(log);
sw.Close();
}
}
2、控制器异常处理 这种方式就在需要进行异常处理的controller中重写OnException()方法即可,因为它本身继承了IExceptionFilter接口
public class ExceptionController : Controller
{
public ActionResult Index()
{
throw new Exception("我抛出异常了!");
}
protected override void OnException(ExceptionContext filterContext)
{
string filePath = Server.MapPath("~/Exception。txt");
StreamWriter sw = System.IO.File.AppendText(filePath);
sw.WriteLine(DateTime.Now.ToString() + ":" + filterContext.Exception.Message);
sw.Close();
base.OnException(filterContext);
Redirect("/");
}
}
3、过滤器异常处理
namespace MyMVC.Controllers
{
public class ExceptionController : Controller
{
[Error]
public ActionResult Index()
{
throw new Exception("过滤器异常!");
}
}
}
public class ErrorAttribute : HandleErrorAttribute
{
public override void OnException(ExceptionContext filterContext)
{
base.OnException(filterContext);
string path = filterContext.HttpContext.Server.MapPath("~/Exception.txt");
StreamWriter sw = System.IO.File.AppendText(path);
sw.WriteLine(DateTime.Now.ToString()+":"+filterContext.Exception.Message);
sw.Close();
}
}
