Here is my regex: @"[^A-Za-z0-9!@$%&*()-=;:'"",.?/\s\[\]]"

and i am doing to remove invalid characters from a string but only plus[+] sign is left.

This is my testing string :

"123!@#$~`abAB~`!@$Now!@$%&*()-=[];:',.?/+"<br />

and output is: 123!@$abAB!@$Now!@$%&*()-=[];:',.?/+

Expected Result : 123!@$abAB!@$Now!@$%&*()-=[];:',.?/

I want to skip the plus[+] sign too. plz help me.
