国家代码 - C＃ [英] Country codes list - C#

问题描述

我有一个字符串，我需要验证，如果它是一个国家代码。文化是德国人。有没有办法，我可以打电话来获得在德国文化国家代码列表，而不必键入出所有的274（？）规范自己的方法？

I have a string which I need to verify if it's a Country code. The culture is German. Is there any method that I can call to get a list of Country codes in a German culture without having to type out all the 274 (?) codes myself?

谢谢，

Thanks, Teja.

推荐答案

当你说国家代码我想你指的是两个字母的代码作为< A HREF =http://www.iso.org/iso/english%5Fcountry%5Fnames%5Fand%5Fcode%5Felements> ISO 3166 。然后你可以使用RegionInfo构造函数来检查，如果你的字符串是一个正确的代码

When you say "country code" I assume you mean the two-letter code as in ISO 3166. Then you can use the RegionInfo constructor to check if your string is a correct code.

string countryCode = "de";
try {
    RegionInfo info = new RegionInfo(countryCode);
}
catch (ArgumentException argEx)
{
    // The code was not a valid country code
}

您也可以，因为你在你的问题的状态，检查它是否是为德语有效的国家代码。然后你只是通过在特定的文化名连同国家代码

You could also, as you state in your question, check if it is a valid country code for the german language. Then you just pass in a specific culture name together with the country code.

string language = "de";
string countryCode = "de";
try {
    RegionInfo info = new RegionInfo(string.Format("{0}-{1}", language, countryCode));
}
catch (ArgumentException argEx)
{
    // The code was not a valid country code for the specified language
}
