我已经使用了Nuget软件包libphonenumber-csharp。
这帮助我创建了一个(荷兰)电话号码验证器,以下是代码片段。没有我的解决方案的其他部分,它将无法编译,但至少你可以了解如何处理这个问题。
public override void Validate()
{
ValidationMessages = new Dictionary<string, string>();
ErrorMessage = string.Empty;
string phoneNumber;
string countryCode = _defaultCountryCode;
bool isValid = (!_isRequired);
if (!string.IsNullOrEmpty(_phoneNumber))
{
var phoneUtil = PhoneNumberUtil.GetInstance();
try
{
phoneNumber = PhoneNumbers.PhoneNumberUtil.Normalize(_phoneNumber);
countryCode = PhoneNumberUtil2.GetRegionCode(phoneNumber, _defaultCountryCode);
PhoneNumber oPhoneNumber = phoneUtil.Parse(phoneNumber, countryCode);
var t1 = oPhoneNumber.NationalNumber;
var t2 = oPhoneNumber.CountryCode;
var formattedNo = phoneUtil.Format(oPhoneNumber, PhoneNumberFormat.E164);
isValid = PhoneNumbers.PhoneNumberUtil.IsViablePhoneNumber(formattedNo);
}
catch (NumberParseException e)
{
var err = e.ToString();
isValid = false;
}
}
if ((isValid) && (!string.IsNullOrEmpty(_phoneNumber)))
{
Regex regexValidator = null;
string regex;
switch (countryCode)
{
case "NL":
if (_phoneNumber.StartsWith("0800") || _phoneNumber.StartsWith("0900"))
{
regex = @"((0800|0900)(-| )?[0-9]{4}([0-9]{3})?$)";
regexValidator = new Regex(regex);
isValid = regexValidator.IsMatch(_phoneNumber);
}
else
{
string phoneNumberCheck = _phoneNumber.Replace("(", "").Replace(")", "").Replace("-", "").Replace(" ", "");
regex = @"^(0031|\+31|0)[1-9][0-9]{8}$";
regexValidator = new Regex(regex);
isValid = regexValidator.IsMatch(phoneNumberCheck);
}
break;
}
}
if (!isValid)
{
ErrorMessage = string.Format(TextProvider.Get(TextProviderConstants.ValMsg_IsInAnIncorrectFormat_0),
ColumnInfoProvider.GetLabel(_labelKey));
ValidationMessages.Add(_messageKey, ErrorMessage);
}
}
我的 PhoneNumberUtil2 类可能也很有用,它是在 nuget 包 libphonenumber-csharp 的基础上构建的:
using System.Collections.Generic;
using System.Globalization;
using System.Linq;
using System.Text;
using PhoneNumbers;
namespace ProjectName.Logic.Miscellaneous
{
public class PhoneNumberUtil2
{
public static string GetRegionCode(string normalizedPhoneNumber, string defaultCountryCode)
{
if (normalizedPhoneNumber.Length > 10)
{
var dict = new Dictionary<string, string>();
dict.Add("7", "RU");
dict.Add("43", "AT");
dict.Add("32", "BE");
dict.Add("45", "DK");
dict.Add("33", "FR");
dict.Add("49", "DE");
dict.Add("39", "IT");
dict.Add("31", "NL");
dict.Add("47", "NO");
dict.Add("34", "ES");
dict.Add("46", "SE");
dict.Add("41", "CH");
dict.Add("90", "TR");
dict.Add("44", "GB");
dict.Add("351", "PT");
dict.Add("353", "IE");
dict.Add("358", "FI");
if (dict.ContainsKey(normalizedPhoneNumber.Substring(0, 3)))
{
return dict[normalizedPhoneNumber.Substring(0, 3)];
}
if (dict.ContainsKey(normalizedPhoneNumber.Substring(0, 2)))
{
return dict[normalizedPhoneNumber.Substring(0, 2)];
}
if (dict.ContainsKey(normalizedPhoneNumber.Substring(0, 1)))
{
return dict[normalizedPhoneNumber.Substring(0, 1)];
}
}
return defaultCountryCode;
}
}
}

吗?这似乎与你之前缩短部分的数字不符。 - Mathiou
