Caps Lock判断
如何判断是否按下大小写键,如果当前是小写,按下Caps Lock 则提示大写字母打开,否则提示小写字母打开
using System; using System.Runtime.InteropServices; namespace testdatetostr { class Program { [DllImport("USER32", SetLastError = true)] static extern short GetKeyState(int nVirtKey); static void Main(string[] args) { Console.WriteLine(GetKeyState(20) == 1 ? "大写字母打开" : "小写字母打开"); Console.ReadKey(); } } }
