C#可调用API接口来获取窗口句柄,代码如下
using System;
using System.Runtime.InteropServices;
namespace tstfindwindow
{
/// <summary>
/// Class1 的摘要说明。
/// </summary>
class Class1
{
[DllImport( "User32.dll ")]
public static extern System.IntPtr FindWindowEx( System.IntPtr parent , System.IntPtr childe , string strclass ,string strname );
/// <summary>
/// 应用程序的主入口点。
/// </summary>
[STAThread]
static void Main(string[] args)
{
//
// TODO: 在此处添加代码以启动应用程序
//
IntPtr p=FindWindowEx(System.IntPtr.Zero,System.IntPtr.Zero,null,"窗口标题");
}
}
遍历所有窗口句柄
using System;
using System.Runtime.InteropServices;
using System.Text;
using System.Collections.Generic;
class CSharpAPIsDemo
{
private delegate bool WNDENUMPROC(IntPtr hWnd, int lParam);
[DllImport("user32.dll")]
private static extern bool EnumWindows(WNDENUMPROC lpEnumFunc, int lParam);
//[DllImport("user32.dll")]
//private static extern IntPtr FindWindowW(string lpClassName, string lpWindowName);
[DllImport("user32.dll")]
private static extern int GetWindowTextW(IntPtr hWnd, [MarshalAs(UnmanagedType.LPWStr)]StringBuilder lpString, int nMaxCount);
[DllImport("user32.dll")]
private static extern int GetClassNameW(IntPtr hWnd, [MarshalAs(UnmanagedType.LPWStr)]StringBuilder lpString, int nMaxCount);
public struct WindowInfo
{
public IntPtr hWnd;
public string szWindowName;
public string szClassName;
}
public WindowInfo[] GetAllDesktopWindows()
{
List<WindowInfo> wndList = new List<WindowInfo>();
//enum all desktop windows
EnumWindows(delegate(IntPtr hWnd, int lParam)
{
WindowInfo wnd = new WindowInfo();
StringBuilder sb = new StringBuilder(256);
//get hwnd
wnd.hWnd = hWnd;
//get window name
GetWindowTextW(hWnd, sb, sb.Capacity);
wnd.szWindowName = sb.ToString();
//get window class
GetClassNameW(hWnd, sb, sb.Capacity);
wnd.szClassName = sb.ToString();
//add it into list
wndList.Add(wnd);
return true;
}, 0);
return wndList.ToArray();
}
}
