Extaspnet上传WORD文档时会发生问题

河蟹社会

如下的代码框架：

1. <asp:FileUpload ID="FileUploadAttDoc" runat="server" /><ext:TriggerBox ID="TriggerBoxAttProject" runat="server" Label="选择项目" TriggerIcon="Search" Width="150px">                        </ext:TriggerBox><asp:Button ID="ButtonSave" runat="server" Text="保存" onclick="ButtonSave_Click" />     

复制代码

当上传WORD文档的时候会发生错误，但是上传其他文件RAR,EXCEL,图片等则不会发生错误：

补充： 如果把ASP.NET的上传控件换成EXT的上传控件，则会出现这个错误：

一个空页面，只放一个 asp:FileUpload 还会出错么？是不是文件太大了
