Need regular expression to check the password policy

and the password policy should :

length of password :minimum 6 letters
2 digits
1 Special sign

What I have tried:

I tried ::
ValidationExpression="^(?=.*\d)(?=.*[$@$!%*?&#'()+,-./:;<=>[\]^_`{|}~"])[A-Za-z\d$@$!%*?&#'()+,-./:;<=>[\]^_`{|}~"]{6,}"

is it write or not?? if not how to write it??

"is it write or not?"
Well what happens when you try it?

You're close, but you need two digits, whereas your pattern only checks for one. Try:
RegEx
^(?=.*\d.*\d)(?=.*[@$!%*?&#'()+,-./:;<=>[\]^_`{|}~"])[A-Za-z\d@$!%*?&#'()+,-./:;<=>[\]^_`{|}~"]{6,}

You should probably also allow for "special" characters other than the ones listed:
RegEx
^(?=.*\d.*\d)(?=.*[^A-Za-z\d]).{6,}

No, you 'want', but it is the wrong tool for the problem.
If password was "ABCDEF12$", RegEx would be Ok, but anything can be mixed, this is what makes the RegEx not appropriate.

You need to build a little piece of code like
set Counters
scan each char in password
  categorize the current char
  update marching Counter
check if Counters match the policy.
