Hi Lynts, please use Code Tags when pasting code on this forum; https://forum.unity.com/threads/using-code-tags-properly.143875/

With regards to the error, your "Characters" array has been passed as an argument where it's expecting a string. You need to properly access the array item in your loop...

Code (CSharp):

1. inputEmail.StartsWith(Characters[i]))
2. inputEmail.EndsWith(Characters[i]))

However, there are better ways to validate strings in C# via the RegEx class. There's a good article covering email validation along with a copy and paste code example, here; Validate Email

 

thanks man ill look at this right now
