C#检查键盘大小写锁定状态
1、命名空间:
using System.Runtime.InteropServices;
2、导入方法
[DllImport("user32.dll", EntryPoint = "GetKeyboardState")] public static extern int GetKeyboardState(byte[] pbKeyState);
3、大小写状态
public static bool CapsLockStatus { get { byte[] bs = new byte[256]; GetKeyboardState(bs); return (bs[0x14] == 1); } }
4、引用,此部分根据你的需要来修改
private void button2_Click(object sender, EventArgs e) { if (CapsLockStatus == true) MessageBox.Show("键盘处于大写锁定状态!"); else MessageBox.Show("键盘处于小写状态!"); }
