How to check if the input string is a valid VB string?

We know that VB string start and end with double quotes " "

So we have to use "" if we want " in VB string.

I wonder if there is a regular expression pattern which will match VB string?.

What is the context here? You only need to escape quotes to let the compiler distinguish between start/end quotes and quotes which are part of the string data. If the string is read during runtime there's no need for double quotes.

Are you trying to detect if the string they entered would be valid if typed into a VB code file? If so the following regular expression should do the trick 

^"(("")|[^"])*"$
