C＃正则表达式，用于空格，字母数字和特殊字符的组合

Question

I am using asp.net 3.5 with C# 2008.

I have a textbox and to validate it I have a regular expression validator. For allowing Alpha-numerics, space and certain special character I am using following regular expression ValidationExpression="[a-zA-Z0-9_. ,'#&$~@!-]*"

Now I want to allow double quotes (") as a special character. For this I have tried ValidationExpression="[a-zA-Z0-9_. ,'#&$~@!\\"-]*" ValidationExpression="[a-zA-Z0-9_. ,'#&$~@!\\"-]*" and ValidationExpression="[a-zA-Z0-9_. ,'#&$~@!"-]*" etc. but gives Parser Error.

Can anyone help?

Answer 1

You need to escape " using "" or "

Your regex should be

^[\w. ,'#&$~@!"-]*$

\\w is similar to [a-zA-Z\\d_]
