私有InputLanguage GetFarsiLanguage()
{

foreach(InputLanguage.InstalledInputLanguages中的InputLanguage lang)
如果(lang.Culture.EnglishName.ToLower().Contains("iran"))
返回lang;

返回null;

}

公共无效YourMethod()
{
如果(InputLanguage.CurrentInputLanguage == GetFarsiLanguage())
MessageBox.Show("System Language is farsi ...");

其他
{
InputLanguage lang = GetFarsiLanguage();
如果(lang == null)
抛出新的NotSupportedException(未安装波斯语键盘.");

InputLanguage.CurrentInputLanguage = lang;
MessageBox.Show(系统语言更改为波斯语.");
}
