我有一个键盘钩子实现,它可以在给定的条件下改变某些文本的输出。要确定如何格式化输出,我需要能够看到哪个窗口处于焦点状态,如果Internet Explorer处于焦点状态,我需要能够确定在该特定选项卡上打开的是哪个URL。
我一直在使用西蒙在以下帖子中发布的代码:Retrieve current URL from C# windows forms application
Process[] localByName = Process.GetProcessesByName("iexplore");
if((Keys)vkCode == Keys.LShiftKey)
{
return CallNextHookEx(_hookID, nCode, wParam, lParam);
}
foreach (Process process in Process.GetProcessesByName("iexplore"))
{
string url = GetInternetExplorerUrl(process);
if (url == null)
continue;
Console.WriteLine("IE Url for '" + process.MainWindowTitle + "' is " + url);
}
由于我正在运行Internet Explorer (并为此打开了网页),我希望/期望看到某种带有URL的输出,显示打开的URL。我没有得到写入控制台的URL,而是什么也得不到。在我尝试使用GetProcessesByName
的情况下,我只得到以下输出:System.Diagnostics.Process[]

要从Internet Explorer选项卡中获取所有URL,您可以执行以下操作:
1.添加对"Microsoft Internet Controls“的引用
URL2.url添加以下代码以获取的:
SHDocVw.ShellWindows shellWindows = new SHDocVw.ShellWindows();
List<string> urls = shellWindows
.Cast<SHDocVw.InternetExplorer>()
.Where(ie => System.IO.Path.GetFileNameWithoutExtension(ie.FullName).ToLower() == "iexplore")
.Select(ie => ie.LocationURL)
.ToList();
foreach (string url in urls)
{
Console.WriteLine(url);
}

这种解决方案是一种老生常谈的工作方式。
主要思想
需要考虑的几件事
获取活动选项卡URL的步骤
为原始活动窗口和原始浏览器窗口状态的主窗口查找名为“CTRL+C
<>H139>还原原始活动窗口。
缺点
代码需求
Clipboard
,Clipboard
和SendKeys
Main
必须具有[STAThread]
属性才能引用System.Windows.Forms
代码
using System.Windows.Forms;
using System.Diagnostics;
using Vanara.PInvoke;

// Get all Internet Explorer processes with a window title
Process[] ieProcs = Process.GetProcessesByName("iexplore")

// Initialize a URL array to hold the active tab URL
string[] ieUrls = new string[ieProcs.Length];
for (int i = 0; i < ieProcs.Length; i++)
{
Process proc = ieProcs[i];
// Remember the initial window style of the process window
User32_Gdi.WindowStyles initialWndStyles = (User32_Gdi.WindowStyles)User32_Gdi.GetWindowLongPtr(proc.MainWindowHandle, User32_Gdi.WindowLongFlags.GWL_STYLE);
