I have a form and I upload a file and I have to verify that the filename has this format input##.txt, where ## are digits.
我有一个表单，我上传了一个文件，我必须验证文件名是否有这个格式的输入##。txt，其中##是数字。
Until now I've had a validator on the upload input and the regular expression that I found is input\d{2}\.txt, but is not enough because the FileUpload control's filename looks like this :
到目前为止，我在上传输入上有一个验证器，我找到的正则表达式是input\d{2}\。txt，但还不够，因为FileUpload控件的文件名如下所示:
C:\Documents and Settings\xyz\Desktop\input01.txt
C:\Documents and Settings\xyz\Desktop\ input01.txt
and I need to validate only the part with input01.txt.
我只需要用input01.txt对部分进行验证。
Could anyone help me?
