C# 为什么IE（8）显示错误的文件名？创建文件时

c# asp.net file internet-explorer web

C# 为什么IE（8）显示错误的文件名？创建文件时,c#,asp.net,file,internet-explorer,web,C#,Asp.net,File,Internet Explorer,Web,我写了这个程序，但在一些borwser（如IE8）中不起作用 **为什么IE8显示错误的文件名？**换句话说，它将更改为unicode名称当使用显式名称时，其工作正常，但当我使用文件名时，其工作不正常我找到了我的源代码请帮帮我非常感谢 <!DOCTYPE html> <html xmlns="http://www.w3.org/1999/xhtml"> <head runat="server"> <title></title

我写了这个程序，但在一些borwser（如IE8）中不起作用 **为什么IE8显示错误的文件名？**换句话说，它将更改为unicode名称

当使用显式名称时，其工作正常，但当我使用文件名时，其工作不正常我找到了我的源代码

请帮帮我非常感谢
