我要评论c#实现的鼠标钩子，可以获取鼠标在屏幕中的坐标，记得要以管理员权限运行才行
复制代码 代码如下:
using system;
using system.collections.generic;
using system.componentmodel;
using system.data;
using system.drawing;
using system.linq;
using system.reflection;
using system.runtime.interopservices;
using system.text;
using system.windows.forms;
namespace app01
{
public partial class form1 : form
{
public delegate int hookproc(int ncode, intptr wparam, intptr lparam);
//定义钩子句柄
public static int hhook = 0;
//定义钩子类型
public const int wh_mouse_ll = 14;
public hookproc myprocedure;
//安装钩子
[dllimport("user32.dll", charset = charset.auto, callingconvention = callingconvention.stdcall)]
public static extern int setwindowshookex(int idhook, hookproc lpfn, intptr hinstance, int threadid);
//卸载钩子
[dllimport("user32.dll", charset = charset.auto, callingconvention = callingconvention.stdcall)]
public static extern bool unhookwindowshookex(int idhook);
//调用下一个钩子
[dllimport("user32.dll", charset = charset.auto, callingconvention = callingconvention.stdcall)]
public static extern int callnexthookex(int idhook, int ncode, intptr wparam, intptr lparam);
[structlayout(layoutkind.sequential)]
public class point
{
public int x;
public int y;
}
[structlayout(layoutkind.sequential)]
public class mousehookstruct
{
public point pt;
public int hwnd;
public int whittestcode;
public int dwextrainfo;
}
public form1()
{
initializecomponent();
}
private void button1_click(object sender, eventargs e)
{
if (hhook == 0)
{
myprocedure = new hookproc(this.mousehookproc);
//这里挂节钩子
hhook = setwindowshookex(wh_mouse_ll, myprocedure, marshal.gethinstance(assembly.getexecutingassembly().getmodules()[0]), 0);
if (hhook == 0)
{
messagebox.show("setwindowshookex failed");
return;
}
button1.text = "卸载钩子";
}
else
{
bool ret = unhookwindowshookex(hhook);
if (ret == false)
{
messagebox.show("unhookwindowshookex failed");
return;
}
hhook = 0;
button1.text = "安装钩子";
}
}
public int mousehookproc(int ncode, intptr wparam, intptr lparam)
{
mousehookstruct mymousehookstruct = (mousehookstruct)marshal.ptrtostructure(lparam, typeof(mousehookstruct));
if (ncode < 0)
{
return callnexthookex(hhook, ncode, wparam, lparam);
}
else
{
string strcaption = "x = " + mymousehookstruct.pt.x.tostring("d") + " y = " + mymousehookstruct.pt.y.tostring("d");
this.text = strcaption;
return callnexthookex(hhook, ncode, wparam, lparam);
}
}
}
}
