var numberProto = phoneUtil.Parse("1234567890", "IT");
var formattedPhone = phoneUtil.Format(numberProto, PhoneNumberFormat.INTERNATIONAL);

Answer 2

@danyolgiax 几乎拥有它。这是你要做的：

var phoneUtil = PhoneNumberUtil.GetInstance();
var numberProto = phoneUtil.Parse("+4915213116250", "ZZ"); //why ZZ means international i don't know
var formattedPhone = phoneUtil.Format(numberProto, PhoneNumberFormat.INTERNATIONAL);

phoneUtil.IsValidNumber如果您不确定电话号码是否有效，请记住使用。还要注意phoneUtil.Parse可能会抛出。
