由于上篇C#操作QQ的TreeView控件以及详细讲解过如何操作其他进程的控件的流程，所以关于如何操作我就不在啰嗦了。传送门：Rolends 主要实现流程如下：
1), 获取列数
获取列数需先获取列的索引指针：
C# Code By wuleba.com
| 1 | columnIndex = WinAPIHelper.SendMessage (lvHwnd, (int) WinAPIHelper.LVM.GETHEADER, 0, 0); |
利用列索引指针去获取列数量：
C# Code By wuleba.com
| 1 | columnCount = WinAPIHelper.SendMessage (new IntPtr (columnIndex), (int) WinAPIHelper.HDM.HDM_GETITEMCOUNT, 0, 0); |
2), 获取行数
C# Code By wuleba.com
| 1 | rowCount = WinAPIHelper.SendMessage (lvHwnd, (int) WinAPIHelper.LVM.GETITEMCOUNT, 0, 0); |
3), 遍历所有cell,使用LVITEM获取需要的数据
C# Code By wuleba.com
| 1 | iRet = WinAPIHelper.SendMessage (lvHwnd, (int) WinAPIHelper.LVM.GETITEMW, j, pItemMemory); |
像这些没有技术难点的东西我会讲的少一点,大家可以查MSDN,需要我的APIHelper类,请留言

这篇代码实现比较滥，大家可以自己拿去改。
