Question

sendmessage C# 鼠标点击

private void KZ_Tick(object sender, EventArgs e)
{
KZ.Stop();
d = 0;
SendMessage(myIntPtr, WM_LBUTTONDOWN,X, Y);
SendMessage(myIntPtr, WM_LBUTTONUP,X ,Y );
F6.Start();
KZ.Start();
}

这里为什么老是说当前上下文中不存在名称 WM_LBUTTONDOWN和当前上下文中不存在名称 WM_LBUTTONUP

Answer 1

WM_LBUTTONDOWN和WM_LBUTTONUP是sdk种定义的常量，c/c++专用，所以你得自己重定义
从网上粘来的，参考下
public enum WMessages : int
{
WM_LBUTTONDOWN = 0x201, //Left mousebutton down
WM_LBUTTONUP = 0x202, //Left mousebutton up
WM_LBUTTONDBLCLK = 0x203, //Left mousebutton doubleclick
WM_RBUTTONDOWN = 0x204, //Right mousebutton down
WM_RBUTTONUP = 0x205, //Right mousebutton up
WM_RBUTTONDBLCLK = 0x206, //Right mousebutton doubleclick
WM_KEYDOWN = 0x100, //Key down
WM_KEYUP = 0x101, //Key up
}
