C# 5.0 カルチャー設定は DefaultThreadCurrentCulture/DefaultThreadCurrentUICulture で行う

WEBアプリは web.config でアプリケーションレベルのカルチャーを設定するとして、


<configuration>
    <system.web>
        <globalization culture="ja-JP" uiCulture="ja-JP" />
    </system.web>
</configuration>

<system.web>

</system.web>

</configuration>

WEBアプリ以外は何でカルチャーを設定するのが良いのか調べました。
結論は、DefaultThreadCurrentCulture と DefaultThreadCurrentUICulture を設定すれば良いです。
ソースコードはGitHubで公開しています。


        static void Main(string[] args)
        {
            //const string = "ja-JP";
            const string cultureName = "ru-RU";

            //CultureInfo.CurrentCulture = new CultureInfo(cultureName, false);
            //CultureInfo.CurrentUICulture = new CultureInfo(cultureName, false);
            CultureInfo.DefaultThreadCurrentCulture = new CultureInfo(cultureName, false);
            CultureInfo.DefaultThreadCurrentUICulture = new CultureInfo(cultureName, false);
            //Thread.CurrentThread.CurrentCulture = new CultureInfo(cultureName, false);
            //Thread.CurrentThread.CurrentUICulture = new CultureInfo(cultureName, false);

            Console.WriteLine("CultureInfo.CurrentCulture.Name : " + CultureInfo.CurrentCulture.Name);
            Console.WriteLine("CultureInfo.CurrentUICulture.Name : " + CultureInfo.CurrentUICulture.Name);
            Console.WriteLine("CultureInfo.DefaultThreadCurrentCulture.Name : " + CultureInfo.DefaultThreadCurrentCulture.Name);
            Console.WriteLine("CultureInfo.DefaultThreadCurrentUICulture.Name : " + CultureInfo.DefaultThreadCurrentUICulture.Name);
            Console.WriteLine("Thread.CurrentThread.CurrentCulture.Name : " + Thread.CurrentThread.CurrentCulture.Name);
            Console.WriteLine("Thread.CurrentThread.CurrentUICulture.Name : " + Thread.CurrentThread.CurrentUICulture.Name);
        }

static void Main(string[] args)

{

//const string = "ja-JP";

const string cultureName = "ru-RU";

//CultureInfo.CurrentCulture = new CultureInfo(cultureName, false);

//CultureInfo.CurrentUICulture = new CultureInfo(cultureName, false);

CultureInfo.DefaultThreadCurrentCulture = new CultureInfo(cultureName, false);

CultureInfo.DefaultThreadCurrentUICulture = new CultureInfo(cultureName, false);

//Thread.CurrentThread.CurrentCulture = new CultureInfo(cultureName, false);

//Thread.CurrentThread.CurrentUICulture = new CultureInfo(cultureName, false);

Console.WriteLine("CultureInfo.CurrentCulture.Name : " + CultureInfo.CurrentCulture.Name);

Console.WriteLine("CultureInfo.CurrentUICulture.Name : " + CultureInfo.CurrentUICulture.Name);

Console.WriteLine("CultureInfo.DefaultThreadCurrentCulture.Name : " + CultureInfo.DefaultThreadCurrentCulture.Name);

Console.WriteLine("CultureInfo.DefaultThreadCurrentUICulture.Name : " + CultureInfo.DefaultThreadCurrentUICulture.Name);

Console.WriteLine("Thread.CurrentThread.CurrentCulture.Name : " + Thread.CurrentThread.CurrentCulture.Name);

Console.WriteLine("Thread.CurrentThread.CurrentUICulture.Name : " + Thread.CurrentThread.CurrentUICulture.Name);

}

実行結果
