推荐答案

从第二个链接听起来很简单. 从您的计算机中读取和更新CAPS或NUM锁定状态应用程序 [ ^ ]

It sounds very simple from 2nd link..check those..
Read and Update CAPS or NUM Lock Status from your Application[^]

public KeyStatusStatusBar(bool CapsLock, bool NumLock)
{
 // This call is required by the Windows.Forms Form Designer.
 InitializeComponent();
 ...
 Application.Idle += new System.EventHandler(OnIdle);
}
...
[DllImport("user32.dll", CharSet=CharSet.Auto, ExactSpelling=true, CallingConvention=CallingConvention.Winapi)]
public static extern short GetKeyState(int keyCode);

public void OnIdle(object sender, EventArgs e)
{
 // Update the panels when the program is idle.
 bool CapsLock = (((ushort) GetKeyState(0x14 /*VK_CAPITAL*/)) & 0xffff) != 0;
 bool NumLock  = (((ushort) GetKeyState(0x90 /*VK_NUMLOCK*/)) & 0xffff) != 0;
 if (CapsLockPanel != null)
 {
  CapsLockPanel.Text = CapsLock ? "CAP" : "";
 }
 if (NumLockPanel != null)
 {
  NumLockPanel.Text  = NumLock  ? "NUM" : "";
 }
}
