Xml序列化间歇性失败

本文介绍了Xml序列化间歇性失败的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述 29岁程序员，3月因学历无情被辞！ 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 rober Microsoft（R）Visual C＃.NET编译器版本7.10.3052。 for Microsoft（R）.NET Framework版本1.1.432 版权所有（C）Microsoft Corporation 2001-2002。保留所有权利 c：\ WINNT \Temp \yxouf9ik.0.cs（132,9）：错误CS0647：发出错误''System.Security.Permissions.PermissionSetAttribut e ''属性 - ''访问被拒绝。 c：\ WINNT \Temp \yxouf9ik.0.cs（396,9）：错误CS0647：发出错误''System.Security。 Permissions.PermissionSetAttribut e''属性 - ''访问被拒绝。 错误：无法获取任务列表 解决方案 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？ - HTH Christoph Schittko [MVP] 软件架构师，.NET Mentor [0] http：// msdn.microsoft.com/xml/defaul...trblshtxsd.asp " Robert" <一个******* @ discussions.microsoft.com>在消息中写道 news：72 ********************************** @ microsof t.com ... 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文件夹中生成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？我们的用户得到一个文件未发现的异常。每天大约发生一次或两次。 感谢 罗伯特 Microsoft（R）Visual C＃.NET编译器版本7.10.3052.4 Microsoft（R）.NET Framework版本1.1.4322 版权所有（C）Microsoft Corporation 2001-2002。保留所有权利。 c：\ WINNT \Temp \yxouf9ik.0.cs（132,9）：错误CS0647：错误发出''System.Security.Permissions。 PermissionSetAttribut e''属性 - ''访问被拒绝。 '' c：\ WINNT \Temp \yxouf9ik.0.cs（396,9）：错误CS0647：错误发出''System.Security.Permissions.PermissionSetAttribut e''属性 - - ''访问被拒绝。 ''错误：无法获取任务列表 Robert， .out file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？ - HTH Christoph Schittko [MVP] 软件架构师，.NET Mentor [0] http：// msdn.microsoft.com/xml/defaul...trblshtxsd.asp " Robert" <一个******* @ discussions.microsoft.com>在消息中写道 news：72 ********************************** @ microsof t.com ... 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文件夹中生成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？我们的用户得到一个文件未发现的异常。每天大约发生一次或两次。 感谢 罗伯特 Microsoft（R）Visual C＃.NET编译器版本7.10.3052.4 Microsoft（R）.NET Framework版本1.1.4322 版权所有（C）Microsoft Corporation 2001-2002。保留所有权利。 c：\ WINNT \Temp \yxouf9ik.0.cs（132,9）：错误CS0647：错误发出''System.Security.Permissions。 PermissionSetAttribut e''属性 - ''访问被拒绝。 '' c：\ WINNT \Temp \yxouf9ik.0.cs（396,9）：错误CS0647：错误发出''System.Security.Permissions.PermissionSetAttribut e''属性 - - ''访问被拒绝。 ''错误：无法获得任务列表 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： Microsoft（R）Visual C＃.NET编译器版本7.10.3052。 for Microsoft（R）.NET Framework版本1.1.432 版权所有（C）Microsoft Corporation 2001-2002。保留所有权利 c：\ WINNT \Temp \yxouf9ik.0.cs（132,9）：错误CS0647：发出错误''System.Security.Permissions.PermissionSetAttribut e ''属性 - ''访问被拒绝。 c：\ WINNT \Temp \yxouf9ik.0.cs（396,9）：错误CS0647：发出错误''System.Security。 Permissions.PermissionSetAttribut e''属性 - ''访问被拒绝。 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.
