使用C＃排列桌面图标

好吧，伙计们，所以这就是我想要实现的目标：

我希望所有无序的桌面图标在点击按钮时排列在桌面的左上角。

这是我正在使用的代码：

[DllImport("user32.dll")] private static extern IntPtr GetDesktopWindow(); [DllImport("user32.dll", CharSet = CharSet.Auto)] public static extern int SendMessage(IntPtr hWnd, uint Msg, uint wParam, int lParam); private void button1_Click(object sender, EventArgs e) { IntPtr hwnd = GetDesktopWindow(); //hwnd for desktop SendMessage(hwnd, LVM_ARRANGE, LVA_ALIGNLEFT, 0); } 

我相信有与LVM_ARRANGE和LVA_ALIGNLEFT相关联的未分配整数，任何人都可以指导我们它们是什么。 我不熟悉使用dll，所以请原谅我，如果我问一个愚蠢的问题。

谢谢！

帮助我们，我使用以下代码，它仍然无法正常工作：

  private void button1_Click(object sender, EventArgs e) { IntPtr hanle = GetHandle(); IntPtr done; done = SendMessage(hanle, LVM_ARRANGE, LVA_ALIGNLEFT, IntPtr.Zero); } public IntPtr GetHandle() { hShellWnd = GetShellWindow(); hDefView = FindWindowEx(hShellWnd, IntPtr.Zero, "SHELLDLL_DefView", null); folderView = FindWindowEx(hDefView, IntPtr.Zero,"SysListView32", null); return folderView; } public const int LVM_FIRST = 0x1000; public const uint LVM_ARRANGE = LVM_FIRST + 22; //public const IntPtr LVA_SNAPTOGRID = 5; IntPtr LVA_ALIGNLEFT = new IntPtr(0x0001); IntPtr hShellWnd; IntPtr hDefView; IntPtr folderView; [DllImport("User32.dll", CharSet = CharSet.Auto)] public static extern IntPtr GetDesktopWindow(); [DllImport("user32.dll")] public static extern IntPtr SendMessage(IntPtr hWnd, uint Msg, IntPtr wParam, IntPtr lParam); [DllImport("user32.dll", SetLastError = true)] public static extern IntPtr FindWindowEx(IntPtr parentHandle, IntPtr childAfter, string className, string windowTitle); [DllImport("user32.dll")] static extern IntPtr GetShellWindow();

我环顾四周，这个样本似乎有效。

 private void button1_Click(object sender, System.EventArgs e) { SendMessage(GetDesktopWindow(), LVM_ARRANGE, LVA_SNAPTOGRID , 0); } public const int LVM_ARRANGE = 4118; public const int LVA_SNAPTOGRID = 5; [DllImport("User32.dll", CharSet=CharSet.Auto)] public static extern IntPtr GetDesktopWindow(); [DllImport("user32.dll")] public static extern int SendMessage( IntPtr hWnd, uint Msg, int wParam, int lParam ); 

它来自以下链接： http ： //www.codeproject.com/Messages/1168661/Auto-Arrange-desktop-icons.aspx

请注意，从头文件

 #define LVA_DEFAULT 0x0000 #define LVA_ALIGNLEFT 0x0001 #define LVA_ALIGNTOP 0x0002 #define LVA_SNAPTOGRID 0x0005 

因此，要左对齐，您要使用int 1。
