C＃切换输入法

有时候程序运行时，需要自动切换到英文输入状态，可通过代码进行控制输入法。

C#

static void Main(string[] args)
{
    Console.WriteLine(GetCultureType());
    SwitchToLanguageMode("en-US");
    Console.WriteLine(GetCultureType());
    Console.ReadLine();
}

/// <summary>
/// 切换输入法
/// </summary>
/// <param name="cultureType">语言项，如zh-CN，en-US</param>
private static void SwitchToLanguageMode(string cultureType)
{
    var installedInputLanguages = InputLanguage.InstalledInputLanguages;

    if (installedInputLanguages.Cast<InputLanguage>().Any(i => i.Culture.Name == cultureType))
    {
        InputLanguage.CurrentInputLanguage = InputLanguage.FromCulture(System.Globalization.CultureInfo.GetCultureInfo(cultureType));
        //CurrentLanguage = cultureType;
    }
}

/// <summary>
/// 获取当前输入法
/// </summary>
/// <returns></returns>
private static string GetCultureType()
{
    var currentInputLanguage = InputLanguage.CurrentInputLanguage;
    var cultureInfo = currentInputLanguage.Culture;
    //同 cultureInfo.IetfLanguageTag;
    return cultureInfo.Name;
}

VB.net

''' <summary>
''' 切换输入法

Public Sub SwitchToLanguageMode(ByVal cultureType As String)
    Dim installedInputLanguages = InputLanguage.InstalledInputLanguages
    For Each language As InputLanguage In InputLanguage.InstalledInputLanguages
        If language.Culture.Name = cultureType Then
            InputLanguage.CurrentInputLanguage = InputLanguage.FromCulture(System.Globalization.CultureInfo.GetCultureInfo(cultureType))
            Exit For
        End If
    Next

End Sub
