Asp.net验证服务器端
问题描述：
大家好
我想从服务器端验证文本框以限制某些外来字符，但在验证过程中还要显示允许哪些字符.
我不想显示允许字符，是否有任何代码可以显示限制字符的允许字符检查.
谢谢

i donot want to display the allow character , Is there any code which will show me the allow character check with the restrict character.

答
是否有任何代码
为什么要求输入代码?听起来好像您需要"正则表达式".
制作正则表达式以限制不允许使用的字符并使用它.这也可以在客户端完成(而不是在服务器上检查！)
Is there any code
Why ask for code? Sounds like you are in need of ''Regular Expression''.
Make a regular expression that restricts the characters not allowed and use it. This can be done on client side too (instead of checking it on server!)
