Powershell remove text after first instance of special character

Question

This is the value that I have to parse.

8.2.4.151.65; HBAAPI(I) v1.3; 3-29-02

I need to remove everything after and including the first instance of ;

So I need my ending result to be 8.2.4.151.65

Answer 1

$s = '8.2.4.151.65; HBAAPI(I) v1.3; 3-29-02'
$s.Substring(0, $s.IndexOf(';'))

Answer 2

Split on the ; and take the first string.

'8.2.4.151.65; HBAAPI(I) v1.3; 3-29-02'.split(';')[0]
