C# 多语言环境下获取时区列表-526互联

如果不需要在A语言下获取B语言的时区列表，可以使用C#自带的

var systemZones = TimeZoneInfo.GetSystemTimeZones();

如果需要在A语言下获取B语言的时区列表，尝试过设置当前进程，线程的Culture是没办法实现的

var cultureInfo = new CultureInfo("en_US");
CultureInfo.CurrentCulture = cultureInfo;
CultureInfo.CurrentUICulture = cultureInfo;
Thread.CurrentThread.CurrentCulture = cultureInfo;
Thread.CurrentThread.CurrentUICulture = cultureInfo;
var systemZones = TimeZoneInfo.GetSystemTimeZones();

可以引入TimeZoneNames和TimerZoneConverter的Nuget包

var dictionary = TZNames.GetDisplayNames("en_US");

可以反射查看该Nuget的实现，实际上是引入了一个json的资源文件进行解析，如果把该资源文件拿出来自己进行获取　　

var filePath = @"Zones\TimeZoneNames.data.json";
var languageCode = "zh_CN";
languageCode = languageCode.Replace("-", "_");
if (!File.Exists(filePath)) return;
using StreamReader file = File.OpenText(filePath);
var jsonContent = file.ReadToEnd();
JObject jsonObject = JObject.Parse(jsonContent);
var displayNames = jsonObject["DisplayNames"];
if (displayNames == null) return;
var containsKey = ((JObject)displayNames).ContainsKey(languageCode);
if (!containsKey)
{
    if (!languageCode.Contains('_')) return;
    var code = languageCode.Split('_');
    var containsCode = ((JObject)displayNames).ContainsKey(code[0]);
    if (!containsCode) return;
    languageCode = code[0];
}

var jToken = displayNames[languageCode];
var jEnumerable = jToken.Children();
foreach (var child in jEnumerable)
{
    if (child is JProperty property)
    {
        // 获取子元素的键和值
        string key = property.Name;
        string val = property.Value.ToString();
    }
}
