Regular Expression for username with particular special character

I have to validate username with special character. For example:

raaghu@09$%^&     
@Raaghu098          
Raaghu         
9raghu  

Only these special characters are allowed: %^&@#$^*:'.-_ 

How can I do this?

This should work: ^(?:[a-zA-Z0-9%^&@#$^*:'.\-_]+)$

    var pattern = @"^(?:[a-zA-Z0-9%^&@#$^*:'.\-_]+)$";
    var validUsername = "raaghu@-09_$%^&";
    var InvalidUsername = "raaghu@09$%^&!";
    
    Regex.IsMatch(validUsername , pattern); // true
    Regex.IsMatch(InvalidUsername , pattern); // false
