Xml序列化间歇性失败 [英] Xml Serialization Intermittent Failure

问题描述

我们有一个执行大量xml序列化的ASP.NET站点。序列化发生在lbolibrary dll中。偶尔我们会在Winnt\temp文件夹中获得一个包含以下内容的.out文件：


C：\ WINNT \ system32> c：\ winnt \microsoft.net \ framework\v1.1.4322\csc.ex e / t：library / utf8output /R:"c:\winnt\assembly\gac\system.xml\1.0.5000.0__b7 7a5c561934e089\system.xml.dll" /R:"c:\winnt\assembly\gac\lbolibrary\1.0.0.0__30b57 061a1ea7c52 \lbolibrary.dll" /R:"c:\winnt\microsoft.net\framework\v1.1.4322\msco rlib.dll" /out:"C:\WINNT\TEMP\yxouf9ik.dll" / debug- / optimize + / w：1" C：\ WINNT \ TEMP \yxouf9ik.0.cs


你能解释一下这个问题吗？我们的用户获得了一个filenotfound异常。这种情况每天发生一次或两次


感谢

解决方案

< blockquote> Robert，


.out文件是XmlSerializer正常工作的一部分。请看看我最近在MSDN [0]上发表的文章，看看是否有助于找到问题的原因。

我在阅读你的问题描述后遇到的问题是：你是否一遍又一遍地实例化XmlSerializer实例，或者你能保留它们吗？b
左右？如果你不保留它们，那么构造函数超载你是否需要实例化实例？

您好Christop


我意识到.out文件的生成是正常的

我的理解是，一旦编译程序集就会消失

但是我之前没有在.out文件中看到以下错误：

错误：无法获得任务lis


我正在使用XmlSerializer（类型）构造函数


你知道是什么原因造成的吗


谢谢

We have an ASP.NET site that performs a lot of xml serialization. The serialization occurs in the lbolibrary dll. Occasionally we get an .out file produced in the Winnt\temp folder that contains the following:

C:\WINNT\system32> "c:\winnt\microsoft.net\framework\v1.1.4322\csc.ex e" /t:library /utf8output /R:"c:\winnt\assembly\gac\system.xml\1.0.5000.0__b7 7a5c561934e089\system.xml.dll" /R:"c:\winnt\assembly\gac\lbolibrary\1.0.0.0__30b57 061a1ea7c52\lbolibrary.dll" /R:"c:\winnt\microsoft.net\framework\v1.1.4322\msco rlib.dll" /out:"C:\WINNT\TEMP\yxouf9ik.dll" /debug- /optimize+ /w:1 "C:\WINNT\TEMP\yxouf9ik.0.cs

Can you explain this problem? Our users get a filenotfound exception. This occurs about once or twice every day

Thank

Robert,

The .out file is part of the normal workings of the XmlSerializer. Take a
look at my recent article on MSDN [0] to see if that helps finding the
source of the problem.

The questions I have though after reading your problem description is: Are
you instantiating XmlSerializer instances over and over or can you keep them
around? If you don''t keep them around, which constructor overload are you
instantiating the instances with?

Hi Christop

I realize that the generation of the .out file is normal
My understanding is that this disappears once the assembly is compiled
However I have not seen following error in an .out file before:

Microsoft (R) Visual C# .NET Compiler version 7.10.3052.
for Microsoft (R) .NET Framework version 1.1.432
Copyright (C) Microsoft Corporation 2001-2002. All rights reserved

c:\WINNT\Temp\yxouf9ik.0.cs(396,9): error CS0647: Error emitting ''System.Security.Permissions.PermissionSetAttribut e'' attribute -- ''Access is denied.
ERROR: could not get the task lis

I am using the XmlSerializer(Type) constructor

Do you have any idea what could cause this

Thanks
