asp.net 2.0 有可以配置,程序出错提示就保存到指定的文件的配置方法吗?

就是不用通过每个页面写程序(如果出错就记录到一个TXT文件里),可以通过WEB.CONFIG或其它方式

因为想解决有时修改上传后,程序出错了,却不知道的

你可以把错误信息以邮件的方式发给你

[jinjazz]

用Global.asax

void Application_Error(object sender, EventArgs e) 
    {
        Exception objErr = Server.GetLastError().GetBaseException();
        Response.Write(objErr.Message);
        Server.ClearError();
    }

添加新项-全局应用程序类-打开Global.asax-输入2楼的代码就可以了

发email：
Dim Mail As MailMessage = New MailMessage(dr("EMailFrom").ToString, dr("EMailTo").ToString)
Mail.Subject = dr("EMailSubject")
Mail.Body = dr("ExceptEMailBody")
Dim SMTP As SmtpClient = New SmtpClient()
SMTP.Host = dr("EMailSMTP")
SMTP.Credentials = New System.Net.NetworkCredential(dr("EMailAccount"), dr("EMailPassword"))
SMTP.Send(Mail)

用log可以么?
或者是自己写个函数,写入文件就可以了啥.

For our projects, we use an httpmodule to handle all unhandled exceptions. This module will log a lot of useful information such as exception info, user info and web server info into database automatically. And we could then view or search all this information daily to find out if there is a security problem, performance problem or bug. Demo code of httpmodule is:
public class ExceptionModule : IHttpModule
{
public void Init(HttpApplication application)
{
application.Error += new EventHandler(OnError);
}

public void OnError(object sender, EventArgs args)
{
HttpApplication application = (HttpApplication)sender;
te_ExceptionLog log = GetExceptionLog(application.Server.GetLastError(), application.Context); // form exception entity in another method
string ExceptionProcessWay = ConfigurationManager.AppSettings["ExceptionProcessWay"]; // how to handle exception? log into db or send mail?
IExceptionProcess server = (IExceptionProcess)Activator.GetObject(typeof(IExceptionProcess), ConfigurationManager.AppSettings["ETSRemotingURL"].ToString());
server.LogException(log, ExceptionProcessWay); // we use .net remoting to access database, you can directly use ado.net here
}
}
Should be aware that, you still need to use customErrors configuration to direct user to a friendly page.
BTW, you can also have a look at ASP.NET 2.0 health monitoring.

首先 用Global.asax中的Application_Error解决的是应用程序错误，他包括所有的应用程序级别的错误，因此这种方法是不详细的，
也是不具体的，建议不用这中方法

其次 要想追踪错误的发生点，应该用写日志文件的方式，专门写个方法，用于写错误日志，这个是比较常见的解决方法
像下边的代码：
private static string ErrorPath = ConfigurationManager.AppSettings["ErrorPath"].ToString();
//上面是读取web.config中的错误路径
public static void Write(string message)
{
DateTime now = DateTime.Now;
int day_now = now.Day;
string path = "";
if (day_now == 1)
{
path = ErrorPath + Convert.ToString(DateTime.Now.Year) + "-" + Convert.ToString(DateTime.Now.Month - 1) + ".txt";
FileInfo fi = new FileInfo(path);
fi.Delete();
}
path = ErrorPath + Convert.ToString(DateTime.Now.Year) + "-" + Convert.ToString(DateTime.Now.Month) + ".txt";
StreamWriter sw = new StreamWriter(path, true);
sw.WriteLine(message);
sw.Close();
}

这么做的好处是看指定日期的错误日志即可知道该天是否发生了错误，错误的内容是什么
