c#如何获得系统所有窗口名称(包括隐藏窗口)

获得窗体的句柄可以用GetWindow方法获得窗体标题用GetWindowText方法，显示隐藏某个窗体用ShowWindow方法，给你举个例子 using System.Runtime.InteropServices; private const int WS_VISIBLE = 268435456;//窗体可见 private const int WS_MINIMIZEBOX = 131072;//有最小化按钮 private const int WS_MAXIMIZEBOX = 65536;//有最大化按钮 private const int WS_BORDER = 8388608;//窗体有边框 private const int GWL_STYLE = (-16);//窗体样式 private const int GW_HWNDFIRST = 0; private const int GW_HWNDNEXT = 2; private const int SW_HIDE = 0; private const int SW_SHOW = 5; [DllImport("User32.dll")] private extern static int GetWindow(int hWnd, int wCmd); [DllImport("User32.dll")] private extern static int GetWindowLongA(int hWnd, int wIndx); [DllImport("user32.dll")] private static extern bool GetWindowText(int hWnd, StringBuilder title, int maxBufSize); [DllImport("user32.dll", CharSet = CharSet.Auto)] private extern static int GetWindowTextLength(IntPtr hWnd); [DllImport("user32.dll")] public static extern int ShowWindow(int hwnd, int nCmdShow); //获得包含窗体可见、有边框、有最大化按钮的窗体的句柄和标题(窗体的属性出这几种外还有很多种) public static List<FromInfo> GetHandleList(int Handle) { List<FromInfo> fromInfo = new List<FromInfo>(); int handle = GetWindow(Handle, GW_HWNDFIRST); while (handle > 0) { int IsTask = WS_VISIBLE | WS_BORDER | WS_MAXIMIZEBOX;//窗体可见、有边框、有最大化按钮 int lngStyle = GetWindowLongA(handle, GWL_STYLE); bool TaskWindow = ((lngStyle & IsTask) == IsTask); if (TaskWindow) { int length = GetWindowTextLength(new IntPtr(handle)); StringBuilder stringBuilder = new StringBuilder(2 * length + 1); GetWindowText(handle, stringBuilder, stringBuilder.Capacity); string strTitle = stringBuilder.ToString(); if (!string.IsNullOrEmpty(strTitle)) { fromInfo.Add(new FromInfo(strTitle, handle)); } else { fromInfo.Add(new FromInfo("", handle)); } } handle = GetWindow(handle, GW_HWNDNEXT); } return fromInfo; } //获得所有窗体的句柄和标题 public static List<FromInfo> GetHandleList(int Handle) { List<FromInfo> fromInfo = new List<FromInfo>(); int handle = GetWindow(Handle, GW_HWNDFIRST); while (handle > 0) { int length = GetWindowTextLength(new IntPtr(handle)); StringBuilder stringBuilder = new StringBuilder(2 * length + 1); GetWindowText(handle, stringBuilder, stringBuilder.Capacity); string strTitle = stringBuilder.ToString(); if (!string.IsNullOrEmpty(strTitle)) { fromInfo.Add(new FromInfo(strTitle, handle)); } else { fromInfo.Add(new FromInfo("", handle)); } handle = GetWindow(handle, GW_HWNDNEXT); } return fromInfo; } public class FromInfo { public FromInfo(string title, int handle) { this.title = title; this.handle = handle; } private string title; private int handle; public string Title { get { return title; } set { title = value; } } public int Handle { get { return handle; } set { handle = value; } } } //获得窗体句柄和标题 private void button1_Click(object sender, EventArgs e) { List<FromInfo> fromInfo = GetHandleList(this.Handle.ToInt32()); } private void button2_Click(object sender, EventArgs e) { //隐藏窗体 ShowWindow(this.Handle.ToInt32(), SW_HIDE); //显示窗体 ShowWindow(this.Handle.ToInt32(), SW_SHOW); }
