InputLanguage 类

  • 项目

提供方法和字段以管理输入语言。无法继承此类。

**命名空间:**System.Windows.Forms
**程序集:**System.Windows.Forms（在 system.windows.forms.dll 中）

语法

声明
Public NotInheritable Class InputLanguage
用法
Dim instance As InputLanguage

public sealed class InputLanguage

public ref class InputLanguage sealed

public final class InputLanguage

public final class InputLanguage

备注

输入语言是区域性/键盘布局对，它可确定键盘上的物理键如何映射或绘制某种语言的字符。输入语言基于一个 Windows 输入区域设置标识符，例如 Platform SDK 函数 GetKeyboardLayout 返回的标识符。输入区域设置标识符又称为键盘布局 (HKL) 值的句柄。

使用所提供的 static 方法查找所有已安装的系统映射，并为线程或进程更改输入语言。调用 CurrentInputLanguage 获取当前输入语言。调用 DefaultInputLanguage 获取默认输入语言。调用 InstalledInputLanguages 获取此系统中所有已安装的语言。获得所有已安装语言的列表后，可使用 CurrentInputLanguage 将当前输入语言更改为其他语言。

示例

下面的代码示例获取已安装语言的列表。该示例要求已实例化 textBox1，并且 textBox1.MultiLine 已设置为 true。

Public Sub GetLanguages()
    ' Gets the list of installed languages.
    Dim lang As InputLanguage
    For Each lang In  InputLanguage.InstalledInputLanguages
        textBox1.Text &= lang.Culture.EnglishName & ControlChars.Cr
    Next lang
End Sub 'GetLanguages

public void GetLanguages() {
    // Gets the list of installed languages.
    foreach(InputLanguage lang in InputLanguage.InstalledInputLanguages) {
       textBox1.Text += lang.Culture.EnglishName + '\n';
    }
}

public:
   void GetLanguages()
   {
      // Gets the list of installed languages.
      for each ( InputLanguage^ lang in InputLanguage::InstalledInputLanguages )
      {
         textBox1->Text = String::Concat( textBox1->Text, lang->Culture->EnglishName, "\n" );
      }
   }

public void GetLanguages()
{
    // Gets the list of installed languages.
    IEnumerator objEnum = InputLanguage.get_InstalledInputLanguages().
        GetEnumerator();
    while (objEnum.MoveNext()) {
        InputLanguage lang = (InputLanguage)objEnum.get_Current();
        textBox1.set_Text(textBox1.get_Text() + lang.get_Culture().
            get_EnglishName() + '\n');
    }
} //GetLanguages

下一个示例将默认输入语言设置为当前输入语言。该示例要求已实例化 textBox1，并且 textBox1.MultiLine 已设置为 true。

Public Sub SetNewCurrentLanguage()
    ' Gets the default, and current languages.
    Dim myDefaultLanguage As InputLanguage = InputLanguage.DefaultInputLanguage
    Dim myCurrentLanguage As InputLanguage = InputLanguage.CurrentInputLanguage
    textBox1.Text = "Current input language is: " & _
        myCurrentLanguage.Culture.EnglishName & ControlChars.Cr
        
    textBox1.Text &= "Default input language is: " & _
        myDefaultLanguage.Culture.EnglishName & ControlChars.Cr
    
    ' Changes the current input language to the default, and prints the new current language.
    InputLanguage.CurrentInputLanguage = myDefaultLanguage
    textBox1.Text &= "Current input language is now: " & _
        myDefaultLanguage.Culture.EnglishName
End Sub 'SetNewCurrentLanguage

public void SetNewCurrentLanguage() {
    // Gets the default, and current languages.
    InputLanguage myDefaultLanguage = InputLanguage.DefaultInputLanguage;
    InputLanguage myCurrentLanguage = InputLanguage.CurrentInputLanguage;
    textBox1.Text = "Current input language is: " + myCurrentLanguage.Culture.EnglishName + '\n';
    textBox1.Text += "Default input language is: " + myDefaultLanguage.Culture.EnglishName + '\n';
 
    // Changes the current input language to the default, and prints the new current language.
    InputLanguage.CurrentInputLanguage = myDefaultLanguage;
    textBox1.Text += "Current input language is now: " + myDefaultLanguage.Culture.EnglishName;
}

public:
   void SetNewCurrentLanguage()
   {
      
      // Gets the default, and current languages.
      InputLanguage^ myDefaultLanguage = InputLanguage::DefaultInputLanguage;
      InputLanguage^ myCurrentLanguage = InputLanguage::CurrentInputLanguage;
      textBox1->Text = String::Format( "Current input language is: {0}\nDefault input language is: {1}\n",
         myCurrentLanguage->Culture->EnglishName, myDefaultLanguage->Culture->EnglishName );
      
      // Changes the current input language to the default, and prints the new current language.
      InputLanguage::CurrentInputLanguage = myDefaultLanguage;
      textBox1->Text = String::Format( "{0}Current input language is now: {1}",
         textBox1->Text, myDefaultLanguage->Culture->EnglishName );
   }

public void SetNewCurrentLanguage()
{
    // Gets the default, and current languages.
    InputLanguage myDefaultLanguage =
        InputLanguage.get_DefaultInputLanguage();
    InputLanguage myCurrentLanguage =
        InputLanguage.get_CurrentInputLanguage();
    textBox1.set_Text("Current input language is: "
        + myCurrentLanguage.get_Culture().get_EnglishName() + '\n');
    textBox1.set_Text(textBox1.get_Text() + "Default input language is: "
        + myDefaultLanguage.get_Culture().get_EnglishName() + '\n');

    // Changes the current input language to the default, 
    // and prints the new current language.
    InputLanguage.set_CurrentInputLanguage(myDefaultLanguage);
    textBox1.set_Text(textBox1.get_Text()
        + "Current input language is now: "
        + myDefaultLanguage.get_Culture().get_EnglishName());
} //SetNewCurrentLanguage
