效果：
键盘，放大缩小，键位大小及字体自适应大小
背景
Windows 提供了一个模拟键盘 API 函数 Keybd_event（），使用该函数可以相应的屏蔽键盘的动作。Keybd_event（）函数能触发一个按键事件，也就是说会产生一个 WM_KEYDOWN 或 WM_KEYUP 消息。

今天介绍的方法是使用第三方库osklib，可以在win10 中不需要管理员权限使用屏幕键盘，该库支持.net framework4以上版本，.netcore3.1以及.net5以上版本，兼容wpf和winform，使用起来也很方便。
首先使用vs创建一个wpf项目（这里我用的是.net5），为项目添加osklib依赖
打开包管理器，搜索 Osklib.Wpf或者在命令行输入命令安装依赖
dotnet add package Osklib.Wpf打开MainWindow.xaml，添加一个Textbox控件，同时为Textbox添加GetFocus事件处理方法
MainWindow.xaml
<Window ...> <Grid> <TextBox Width="120" Margin="297,125,0,0" HorizontalAlignment="Left" VerticalAlignment="Top" Text="" TextWrapping="Wrap" GotFocus="TextBox_GotFocus"/> </Grid> </Window>MainWindow.xaml.cs
using System; using System.Windows; namespace WpfApp1 { public partial class MainWindow : Window { public MainWindow() { InitializeComponent(); } private void TextBox_GotFocus(object sender, RoutedEventArgs e) { try { Osklib.OnScreenKeyboard.Show(); } catch (Exception ex) { MessageBox.Show(ex.Message); } } } }编译运行，点击文本框输入，弹出屏幕键盘效果如下：
官方示例中的OnScreenKeyboardSettings.EnableForTextBoxes = true测试中没有效果，可能是操作系统版本问题，直接调用Osklib.OnScreenKeyboard.Show();是没有问题
这个是触发单个Textbox控件的GotFocus来弹出屏幕按键，如果要全局控制所有Textbox输入来弹框，方法有很多，这里介绍最简单方法，因为GotFocus是路由事件，只要监听MainWindow的GotFocus事件，就可以监听到所有Textbox的GotFocus事件，但需要在事件里加上判断语句如下
private void Window_GotFocus(object sender, RoutedEventArgs e) { // 不是Textbox不弹出屏幕键盘 if (!(e.OriginalSource is TextBox)) return; try { Osklib.OnScreenKeyboard.Show(); } catch (Exception ex) { MessageBox.Show(ex.Message); } }如图，只有Textbox1和Textbox2能触发屏幕键盘，而PasswordBox不会触发屏幕键盘
对于非路由事件，不能用这种方法
最后附上osklib库地址：https://github.com/AlexeiScherbakov/osklib

Process.Start(@“C:\Windows\System32\osk.exe”)
却总是报错，说是找不到文件。于是我想单独把那个文件拷贝出来，看看能否使用，后来发现只能用管理员模式才能够打开。
于是，我便把osk.exe文件拷贝到程序目录下，然后写了个方法：
public void ExecuteAsAdmin()
{
Process proc = new Process();
proc.StartInfo.FileName =Environment.CurrentDirectory+ @"\Resources\ExcuteFile\osk.exe";
proc.StartInfo.UseShellExecute = true;
proc.StartInfo.Verb = “runas”;
proc.Start();
}
唯一不好之处在于弹出的虚拟键盘位置不是很理想，需要自己调节。
经测试，可以运行，大家也可以试试。
