特定进程的 C# 参数，使用 url 打开浏览器 [英] C# Arguments for a specific process, open browser with url

问题描述

我正在编写一个应用程序，它应该通过单击按钮打开某个进程.但是，用户可以添加新按钮.我将以下代码用于在按钮单击时启动进程的操作:

I am writing an application that is supposed to open a certain process on the click of a button. However, the user has the ability to add new buttons. I'm using the following code for the action that occurs that starts the process on button click:

        private void StartProcess(string path)
    {
        ProcessStartInfo StartInformation = new ProcessStartInfo();

        StartInformation.FileName = path;

        Process process = Process.Start(StartInformation);

        process.EnableRaisingEvents = true;
    }
    private void ClickFunc(object sender, RoutedEventArgs e)
    {
        if (File.Exists(ProgramPath))
        {
            StartProcess(ProgramPath);
        }
        else
        {
            MessageBox.Show("Specified path does not exist, please try again.", "Bad File Path Error", MessageBoxButton.OK);
        }
    }

我想要完成的是，当用户为网页创建按钮时，它会打开浏览器，然后打开网页.有什么想法吗?

What I'm trying to accomplish is, when the user creates a button for a webpage, it opens the browser, then the webpage. Any ideas?

先谢谢你！

推荐答案

要开始使用特定的 url 打开浏览器的过程，您可以尝试以下操作:

To start a process to open the browser with a specific url you can try this:

string url = "http://www.stackoverflow.com";

var process = System.Diagnostics.Process.Start(url);

但有时如果您的浏览器路径有问题，则无法正常工作.下面的函数为您提供了机器中浏览器的路径.

But sometimes if you have problems with the path of your browser, it cannot work properly. The function bellow gives you the path of the browser in the machine.

public static string GetDefaultBrowserPath()
{
    string urlAssociation = @"Software\Microsoft\Windows\Shell\Associations\UrlAssociations\http";
    string browserPathKey = @"$BROWSER$\shell\open\command";

    RegistryKey userChoiceKey = null;
    string browserPath = "";

    try
    {
        //Read default browser path from userChoiceLKey
        userChoiceKey = Registry.CurrentUser.OpenSubKey(urlAssociation + @"\UserChoice", false);

        //If user choice was not found, try machine default
        if (userChoiceKey == null)
        {
            //Read default browser path from Win XP registry key
            var browserKey = Registry.ClassesRoot.OpenSubKey(@"HTTP\shell\open\command", false);

            //If browser path wasn’t found, try Win Vista (and newer) registry key
            if (browserKey == null)
            {
                browserKey =
                Registry.CurrentUser.OpenSubKey(
                urlAssociation, false);
            }
            var path = CleanifyBrowserPath(browserKey.GetValue(null) as string);
            browserKey.Close();
            return path;
        }
        else
        {
            // user defined browser choice was found
            string progId = (userChoiceKey.GetValue("ProgId").ToString());
            userChoiceKey.Close();

            // now look up the path of the executable
            string concreteBrowserKey = browserPathKey.Replace("$BROWSER$", progId);
            var kp = Registry.ClassesRoot.OpenSubKey(concreteBrowserKey, false);
            browserPath = CleanifyBrowserPath(kp.GetValue(null) as string);
            kp.Close();
            return browserPath;
        }
    }
    catch(Exception ex)
    {
        return "";  
    }
}

您可以使用浏览器的路径和网站的网址，例如:

And you can use the path of the browser and the url of website, for sample:

string url = "http://www.stackoverflow.com";

var process = System.Diagnostics.Process.Start(GetDefaultBrowserPath(), url);

在 url 字符串中，您可以传递网页链接.它将使用网址打开浏览器.

In the url string you can pass the webpage link. It will open the browser with the url.
