Asp.Net Ajax工具包AsyncFileUpload - “文件附加无效”错误

我想从Asp.net Ajax控件工具包（2009年9月30日稳定版本：30930）使用AsyncFileUpload控件。我创建了一个演示应用程序，并且控件正常工作。文件上传，一切都很好。Asp.Net Ajax工具包AsyncFileUpload - “文件附加无效”错误

当我尝试在我的真实应用程序中使用该控件时，我总是收到一个错误，指出“附加的文件无效”。当上传的文件为空时，AsyncFileUpload控件返回这个。

要隔离问题，我创建了一个新的母版页，与我的演示应用程序中的母版页完全一样。我还创建了一个与我的演示应用程序中的页面完全相同的aspx页面。上传仍然失败，并显示“附件无效”错误。

我还比较了真实应用程序和演示应用程序的web.config，并且无法识别任何应该处理的差异。

下面的代码是我的真实应用程序中的测试代码。此代码与演示应用程序中正在运行的代码完全相同，但具有不同的类名和文件名。下面列出的web.config来自实际应用程序，其中删除了appsettings和connectionstrings。

在这一点上，我完全难倒了。

然具有默认的web.config，jquery的1.4.1样品，并且AjaxControlToolkit 3.5 。50731;将母版页切换到ToolkitScriptManager并且工作正常。切换到您的web.config（也创建App_Code \ CS | VBCode文件夹）后，我遇到了错误。 – user423430 2011-09-06 19:48:04

函数startUpload（sender，args）{（'＃uploadMessage p'）。html（）; $（'＃uploadMessage'）。hide（）; } $（'＃uploadMessage p'）。html（）;没有做任何事情。它会将html返回给一个变量或某个东西，但是当以这种方式使用它时，它不会做任何我相信的事情。你想删除现有的HTML吗？ $（'＃uploadMessage p'）。html（''）或$（'＃uploadMessage p'）。empty（）;我怀疑这是问题所在，但是jQuery没有正确使用。 – Hcabnettek 2011-09-14 20:05:51

此特定.NET 3.5示例中的问题是将控件名称分隔符从'_'更改为'：'。 AsyncFileUpload控件做了一个非常头疼的工作，检查它是否应该处理文件上传。 http://ajaxcontroltoolkit.codeplex.com/workitem/26975 – user423430 2011-09-06 20:57:27

是否有可能超出上传限制？你上传的文件大小是多少？

你可以在你的web.config中设置的大小：

<system.web> 
    <httpRuntime executionTimeout="110" maxRequestLength="20000" /> 
</system.web>

有时演示环境与生产环境不同。你是否检查过保存文件的目录？ – Pbirkoff 2010-02-23 11:11:21

如果您已经迁移了您的webproject，则user423430的解决方案是正确的：当您自动将VS 2003 Web项目迁移到VS 2005时，Web.config将自动进行修改。其中添加了<xhtmlConformance mode="Legacy" />。它建议报告到不与AJAX使用它：

http://weblogs.asp.net/scottgu/archive/2006/12/10/gotcha-don-t-use-xhtmlconformance-mode-legacy-with-asp-net-ajax.aspx

（ASP.NET 1.0和1.1不发射从它的许多服务器控件的XHTML兼容的标记ASP.NET 2.0改变了这种并默认。从所有的控制发射XHTML兼容的标记。）
