asp.net 程序异常捕获全局处理,生成错误日志
只需要把以下代码粘贴到Global.asax 文件中即可
private void Application_Error(object sender, EventArgs e)
{
// 在出现未处理的错误时运行的代码
try
{
Exception objErr = Server.GetLastError().GetBaseException();
string error = "发生异常页: " + Request.Url.ToString() + "<br>";
error += "异常信息: " + objErr.Message + "<br>";
Server.ClearError();
Application["error"] = error;
//Response.Redirect("ErrorPage.html");
// 在出现未处理的错误时运行的代码
string errortime = string.Empty;
string erroraddr = string.Empty;
string errorinfo = string.Empty;
string errorsource = string.Empty;
string errortrace = string.Empty;
error += "发生时间:" + System.DateTime.Now.ToString() + "<br>";
errortime = "发生时间:" + System.DateTime.Now.ToString();
error += "发生异常页: " + Request.Url.ToString() + "<br>";
erroraddr = "发生异常页: " + Request.Url.ToString();
error += "异常信息: " + objErr.Message + "<br>";
errorinfo = "异常信息: " + objErr.Message;
errorsource = "错误源:" + objErr.Source;
errortrace = "堆栈信息:" + objErr.StackTrace;
error += "--------------------------------------<br>";
Server.ClearError();
Application["error"] = error;
//独占方式,因为文件只能由一个进程写入.
if (objErr.Source.ToLower() != "system.web")
{
System.IO.StreamWriter writer = null;
try
{
lock (this)
{
// 写入日志
string year = DateTime.Now.Year.ToString();
string month = DateTime.Now.Month.ToString();
string path = string.Empty;
string filename = "/ErrorLog" + DateTime.Now.Day.ToString() + ".txt";
path = @"D:/蜜蜂服务网系统错误日志/ErrorLog/" + year + month;
//如果目录不存在则创建
if (!System.IO.Directory.Exists(path))
{
System.IO.Directory.CreateDirectory(path);
}
System.IO.FileInfo file = new System.IO.FileInfo(path + filename);
writer = new System.IO.StreamWriter(file.FullName, true);
writer.WriteLine("用户IP:" + Request.UserHostAddress);
writer.WriteLine(errortime);
writer.WriteLine(erroraddr);
writer.WriteLine(errorinfo);
writer.WriteLine(errorsource);
writer.WriteLine(errortrace);
writer.WriteLine("--------------------------------------------------------------------------------------");
}
}
finally
{
if (writer != null)
writer.Close();
}
}
}
catch { }
}
