/**//// <summary>

//把错误信息发送到作者


string strPageUrl = Request.Path;


Exception ErrorInfo =Server.GetLastError();


//Server.ClearError();


string strMessage = "Url:" + strPageUrl + "</br>";


strMessage = strMessage + " Error: ";


strMessage = strMessage + ErrorInfo.ToString() + "</br>";

Mymessage.Subject = "ASP.NET Error";


Mymessage.BodyFormat = MailFormat.Text;


Mymessage.Body = strMessage;




//SmtpMail.SmtpServer = " ";


SmtpMail.Send(Mymessage);

将错误写入系统日志


string strMessage = Server.GetLastError().Message;


//Response.Write(strMessage);


Server.ClearError();


//以下把信息写入windows日志


//要把aspnet用户添加到管理员组中，以便有写注册表权限


if(!EventLog.SourceExists("mySource"))


EventLog.CreateEventSource("mySource","myLog");


EventLog Event = new EventLog();


Event.Source = "mySource";


Event.WriteEntry( System.DateTime .Now .ToString (),EventLogEntryType.Warning);


//EventLog.Delete("myLog");


//throw new Exception("我处理不了！");

将错误信息写入输出窗口


System.Diagnostics .Debug .WriteLine( 想要输出的值);

将错误信息写入目录下的log


System.Diagnostics.Trace.Listeners.Clear();
System.Diagnostics.Trace.AutoFlush=true;

string strPath = string.Empty;
strPath = Page.Server.MapPath (".") ;
strPath += @"/app.log";

FileStream fs = new FileStream( strPath, FileMode.Append , FileAccess.Write );
System.Diagnostics .Trace.Listeners.Add( new System.Diagnostics .TextWriterTraceListener( fs ) );

System.Diagnostics .Trace .WriteLine("star");
System.Diagnostics .Trace .WriteLine(System.DateTime.Now.ToLongTimeString () );
System.Diagnostics .Trace .WriteLine( Page.ToString());
System.Diagnostics .Trace .WriteLine("end");

fs.Close ();
