        // This will throw an exception if there is no such process.
        Process localById = Process.GetProcessById(1234);

But accroding to doc:

The token68 syntax allows the 66 unreserved URI characters
   ([RFC3986]), plus a few others, so that it can hold a base64,
   base64url (URL and filename safe alphabet), base32, or base16 (hex)
   encoding, with or without padding, but excluding whitespace
   ([RFC4648]).

It can hold a base64 string, and a base64 string may have = padding.
