不是很清楚, 可能要看接com口,和usb口两种方式吧
告诉你一个简单的方法，通过API GetKeyState()函数可以取得按键(包括鼠标按钮)的状态using System.Runtime.InteropServices;[DllImport("user32.dll")] public static extern short GetKeyState(int nVirtKey); public const int VK_LBUTTON = 1; public const int VK_RBUTTON = 2;这样判断 if (GetKeyState(VK_LBUTTON) & 0x80) == 0x80) /* TODO 左键按下 */ ;

public static extern short GetKeyState(int nVirtKey);
public const int VK_LBUTTON = 1;
public const int VK_RBUTTON = 2;这样判断
if (GetKeyState(VK_LBUTTON) & 0x80) == 0x80)
/* TODO 左键按下 */ ;
/* TODO 左键按下 */ ;
else /* TODO 左键没按下 */ ;
可能还得是hbxtlhx(平民百姓)的办法
支持hbxtlhx(平民百姓)
能实现,但是有个问题,就是timer捕捉的时候是按时间频率来的,假如频率是100ms/次
我一次按下鼠标的过程,假设是1s,那么按一次鼠标就有10次事件了

需要加一个字段来标记一下是否正在处理
参考如下处理方法：private void timer1_Tick(object sender, EventArgs e)
{
if ((GetKeyState(VK_LBUTTON) & 0x80) == 0x80)
{
timer1.Enabled = false;
contextMenuStrip1.Show();
}
}private void contextMenuStrip1_Closed(object sender,
ToolStripDropDownClosedEventArgs e)
{
timer1.Enabled = true;
}
