从C＃窗口获取当前URL表单应用程序 [英] Retrieve current URL from C# windows forms application

问题描述

我一直在设计使用Visual C＃程序和整个的问题都带着制作与网页浏览器我的程序进行交互。基本上，我需要的是检索网页浏览器（IE浏览器，火狐，Chrome等）的URL地址。

I have been designing a program using Visual C# and have came across an issue with making my program interact with web browsers. Basically what I need is to retrieve the URL address from a web browser (Internet Explorer, Firefox, Chrome etc...).

我想这不会是太困难了一项任务，但是，研究和试验好多天之后，它看起来几乎是不可能的！到目前为止，我所遇到的这...

I figured this wouldn't be too difficult of a task, but after days and days of research and tests, it seems almost impossible! Thus far, I have come across this...

获取Firefox的网址是什么？

它具有$ C $低于C：

Which has the code below:

using NDde.Client;
Class Test
{
    public static string GetFirefoxURL()
    {
        DdeClient dde = new DdeClient("Firefox", "WWW_GetWindowInfo");
        dde.Connect();
        string url = dde.Request("URL", int.MaxValue);
        dde.Disconnect();
        return url;
    }
}

这是完美的火狐，但由于某些原因，我不能让它与别的工作。我已经改变的code部分火狐到Iexplore在，说像我发现所有在互联网上，以及尝试其他形式的EX pressing Internet Explorer中，我得到了以下错误：

Which is perfect for Firefox, but for some reason I cannot get it to work with anything else. I have changed the portion of the code that says "Firefox" to "Iexplore" like I found all over the internet, along with trying other forms of expressing Internet Explorer, and I get the following error:

客户端无法连接到IEXPLORER | WWW_GetWindowInfo，确保服务器应用程序正在运行，并且它支持指定的服务名和主题名称对

"Client failed to connect to "IExplorer|WWW_GetWindowInfo", Make sure the server application is running and that it supports the specified service name and topic name pair"

在这个问题上的任何帮助将非常AP preciated，因为它已成为一项艰巨的任务弄清楚。

Any help on the issue would be much appreciated as it has become quite a task to figure out.

推荐答案

这是我到目前为止（虽然Chrome浏览器我没有找到任何有用的文章上，比使用FindWindowEx其他（我特别不喜欢这种方法，个人）。

Here's what I have so far (though Chrome I'm not finding any helpful articles on, other than using FindWindowEx (I don't particularly like that method, personally).

public class BrowserLocation

    /// <summary>
    /// Structure to hold the details regarding a browed location
    /// </summary>
    public struct URLDetails

        /// URL (location)
        /// </summary>
        public String URL;

        /// <summary>
        /// Document title
        /// </summary>
        public String Title;
    }

    #region Internet Explorer

    // requires the following DLL added as a reference:
    // C:\Windows\System32\shdocvw.dll

    public static URLDetails[] InternetExplorer()
    {
        System.Collections.Generic.List<URLDetails> URLs = new System.Collections.Generic.List<URLDetails>();
        var shellWindows = new SHDocVw.ShellWindows();
        foreach (SHDocVw.InternetExplorer ie in shellWindows)
            URLs.Add(new URLDetails() { URL = ie.LocationURL, Title = ie.LocationName });
        return URLs.ToArray();
    }

    #region Firefox

    // This requires NDde

    public static URLDetails[] Firefox()
    {
        NDde.Client.DdeClient dde = new NDde.Client.DdeClient("Firefox", "WWW_GetWindowInfo");
        try

            dde.Connect();
            String url = dde.Request("URL", Int32.MaxValue);
            dde.Disconnect();

            Int32 stop = url.IndexOf('"', 1);
            return new URLDetails[]{
