更改系统语言C#

Question

我正在编写一个应用程序,当应用程序本身没有聚焦时,我需要更改系统的语言.我担心这样做的唯一方法就是使用我目前无法完全理解的Windows钩子.有什么想法吗？

编辑:解决方案

[DllImport("user32.dll")]
private static extern bool PostMessage(int hhwnd, uint msg, IntPtr wparam, IntPtr lparam);

[DllImport("user32.dll")]
private static extern IntPtr LoadKeyboardLayout(string pwszKLID, uint Flags);

private static uint WM_INPUTLANGCHANGEREQUEST = 0x0050;
private static int HWND_BROADCAST = 0xffff;
private static string en_US = "00000409";
private static uint KLF_ACTIVATE = 1;

private static void ChangeLanguage()
{
    PostMessage(HWND_BROADCAST,WM_INPUTLANGCHANGEREQUEST, IntPtr.Zero ,LoadKeyboardLayout(en_US,KLF_ACTIVATE));
}

Answer 1

要更改输入语言，您可以使用以下代码：

private void ChangeKeboardLayout(System.Globalization.CultureInfo CultureInfo)
    {
        InputLanguage c = InputLanguage.FromCulture(CultureInfo);
        InputLanguage.CurrentInputLanguage = c;
    }

只要您的应用程序（或您的线程）打开，您就可以执行此操作。
