Maneira 1 - mais simples
Default.aspx
NADA
Default.aspx.cs
protected void Page_Load(object sender, EventArgs e)
{
// isso vai causar um erro
string s = Request.Cookies["NaoExiste"].Value;
}
Erro.aspx
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Erro.aspx.cs" Inherits="Erro" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<title></title>
</head>
<body>
<form id="form1" runat="server">
<div>
<h2>Deu erro</h2>
</div>
</form>
</body>
</html>
Erro.aspx.cs
protected void Page_Load(object sender, EventArgs e)
{
Response.Write("Origem: " + Request.QueryString["aspxerrorpath"].ToString());
}
web.config
<?xml version="1.0"?>
<configuration>
<system.web>
<compilation debug="true" targetFramework="4.0"/>
<customErrors mode="On" defaultRedirect="~/Erro.aspx">
<error statusCode="404" redirect="~/Erro.aspx"/>
<error statusCode="403" redirect="~/Erro.aspx"/>
</customErrors>
</system.web>
</configuration>
Maneira 2 - com mais detalhes
Default.aspx
NADA
Default.aspx.cs
protected void Page_Load(object sender, EventArgs e)
{
// isso vai causar um erro
string s = Request.Cookies["NaoExiste"].Value;
}
Erro.aspx
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Erro.aspx.cs" Inherits="Erro" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head id="Head1" runat="server">
<title></title>
</head>
<body>
<form id="form1" runat="server">
<div>
<h2>Deu erro</h2>
</div>
</form>
</body>
</html>
Erro.aspx.cs
protected void Page_Load(object sender, EventArgs e)
{
// Usa Server.GetLastError para receber o erro corrente
Exception CurrentException = Server.GetLastError();
// Mostra a mensagem principal
Response.Write("<h1>Mensagem de erro: " + CurrentException.Message + "</h1>");
Response.Write("<p>Fonte:</p>");
Response.Write(CurrentException.Source);
Response.Write("<p>Trace:</p>");
Response.Write(CurrentException.StackTrace);
Response.Write("<p>Inner:</p>");
Response.Write(CurrentException.InnerException);
// Detalhes
Response.Write("<p>Detalhes:</p>");
Response.Write(CurrentException.ToString());
}
web.config
<?xml version="1.0"?>
<configuration>
<system.web>
<customErrors mode="On" defaultRedirect="~/Erro.aspx" redirectMode="ResponseRewrite"/>
<compilation debug="true"/></system.web>
</configuration>
Maneira 3 - Usando Application_Error do Global.asax
Default.aspx
NADA
Default.aspx.cs
protected void Page_Load(object sender, EventArgs e)
{
// isso vai causar um erro
string s = Request.Cookies["NaoExiste"].Value;
}
Erro.aspx
Não tem este arquivo!
web.config (aqui tá o pulo do gato)
NAO TA FUNCIONANDO
<configuration>
<system.web>
<compilation debug="true" targetFramework="4.0"/>
<customErrors mode="On" defaultRedirect="~/Erro.aspx" redirectMode="ResponseRewrite" />
</system.web>
</configuration>
Global.asax (global application class)
void Application_Error(object sender, EventArgs e)
{
// Usa Server.GetLastError para receber o erro corrente
Exception CurrentException = Server.GetLastError();
// Mostra a mensagem principal
Response.Write("<h1>Mensagem de erro: " + CurrentException.Message + "</h1>");
Response.Write("<p>Fonte:</p>");
Response.Write(CurrentException.Source);
Response.Write("<p>Trace:</p>");
Response.Write(CurrentException.StackTrace);
Response.Write("<p>Inner:</p>");
Response.Write(CurrentException.InnerException);
// Detalhes
Response.Write("<p>Detalhes:</p>");
Response.Write(CurrentException.ToString());
}
