Response.Redirect not working in Global.asax
提问by
I have created an error page to show a general message for all unhandled exceptions.
我创建了一个错误页面来显示所有未处理异常的一般消息。
This is the code in Global.asax
这是 Global.asax 中的代码
HttpContext ctx = HttpContext.Current;
string e404_PAGE = ctx.Request.AppRelativeCurrentExecutionFilePath.ToString();
string e404_LINE = ctx.Server.GetLastError().InnerException.StackTrace.Substring(ctx.Server.GetLastError().InnerException.StackTrace.LastIndexOf(":line ") + 6, ctx.Server.GetLastError().InnerException.StackTrace.Substring(ctx.Server.GetLastError().InnerException.StackTrace.LastIndexOf(":line ") + 6).IndexOf(" ")).ToString();
string e404_MESSAGE = ctx.Server.GetLastError().InnerException.Message.ToString();
string e404_METHODNAME = ctx.Server.GetLastError().InnerException.TargetSite.ToString();
string e404_STACKTRACE = ctx.Server.GetLastError().InnerException.StackTrace.ToString();
string e404_URL = ctx.Request.Url.ToString();
string e404_DATE = ctx.Timestamp.ToString("yyyy-MM-dd HH:mm:ss");
string e404_USER = ctx.User.Identity.Name.ToString();
string e404_IP = ctx.Request.UserHostAddress.ToString();
// * * * //
System.Data.SqlClient.SqlConnection sql_conn;
sql_conn = new System.Data.SqlClient.SqlConnection(ConfigurationManager.ConnectionStrings["myConnectionString"].ToString());
sql_conn.Open();
string query = @"insert into UnhandledExceptions(Message, Page, Line, MethodName, StackTrace, URL, Date, [User], IP)
values(@Message, @Page, @Line, @MethodName, @StackTrace, @URL, @Date, @User, @IP)
select scope_identity();";
System.Data.SqlClient.SqlCommand com = new System.Data.SqlClient.SqlCommand(query, sql_conn);
com.Parameters.AddWithValue("@Message", e404_MESSAGE);
com.Parameters.AddWithValue("@Page", e404_PAGE);
com.Parameters.AddWithValue("@Line", e404_LINE);
com.Parameters.AddWithValue("@MethodName", e404_METHODNAME);
com.Parameters.AddWithValue("@StackTrace", e404_STACKTRACE);
com.Parameters.AddWithValue("@URL", e404_URL);
com.Parameters.AddWithValue("@Date", e404_DATE);
com.Parameters.AddWithValue("@User", e404_USER);
com.Parameters.AddWithValue("@IP", e404_IP);
string e404_ID = com.ExecuteScalar().ToString();
sql_conn.Close();
// * * * //
Session["e404_ID"] = e404_ID;
Response.Redirect("~/Error.aspx");
When I publish the website, the user is not being redirected to the error page.
当我发布网站时，用户没有被重定向到错误页面。
All the code until the last line works fine. Any suggestion?
直到最后一行的所有代码都可以正常工作。有什么建议吗？

Replace Response.Redirect("~/Error.aspx");with:
替换Response.Redirect("~/Error.aspx");为：
// You've handled the error, so clear it. Leaving the server in an error state can cause unintended side effects as the server continues its attempts to handle the error.
Server.ClearError();
// Possible that a partially rendered page has already been written to response buffer before encountering error, so clear it.
Response.Clear();
// Finally redirect, transfer, or render a error view
Response.Redirect("~/Error.aspx");
