Can someone provide me with a regex string that I can use in C# for password validation?  The requirements are as follows:

Character length: 7-30.
Must contain at least one number.
Must contain at least one symbol/special character.
Remaining characters can contain any combination of upper/lower case letters, numbers and symbols.

Thanks!

hi  
mdtanner,

Try the following regex

^.*(?=.{7,})(?=.*[0-9])(?=.*[@#$%^&+=]).*$

This will check the follwoing conditions

Character length: 7 (won't check the max length as 30 - put the maxlength of the textbox to 30)
Must contain at least one number.
Must contain at least one symbol/special character- (])(?=.*[@#$%^&+=] are the included special characters)
