Process.Start("http://www.google.com");

Process.Start([your url]) is indeed the answer, in all but extremely niche cases. For completeness, however, I will mention that we ran into such a niche case a while back: if you're trying to open a "file:\" url (in our case, to show the local installed copy of our webhelp), in launching from the shell, the parameters to the url were thrown out.
Process.Start([your url]) 确实是答案，除了非常小众的情况。然而，为了完整起见，我会提到我们不久前遇到了这样一个小众案例：如果您尝试打开“file:\” url（在我们的例子中，显示我们的 webhelp 的本地安装副本），在从 shell 启动时，url 的参数被抛出。
Our rather hackish solution, which I don't recommend unless you encounter a problem with the "correct" solution, looked something like this:
我们相当黑客的解决方案，除非您遇到“正确”解决方案的问题，否则我不推荐它，看起来像这样：
In the click handler for the button:
在按钮的点击处理程序中：
string browserPath = GetBrowserPath();
if (browserPath == string.Empty)
browserPath = "iexplore";
Process process = new Process();
process.StartInfo = new ProcessStartInfo(browserPath);
process.StartInfo.Arguments = "\"" + [whatever url you're trying to open] + "\"";
process.Start();
The ugly function that you shouldn't use unless Process.Start([your url]) doesn't do what you expect it's going to:
除非 Process.Start([your url]) 不符合您的预期，否则您不应该使用丑陋的函数：
private static string GetBrowserPath()
{
string browser = string.Empty;
RegistryKey key = null;
try
{
// try location of default browser path in XP
key = Registry.ClassesRoot.OpenSubKey(@"HTTP\shell\open\command", false);
// try location of default browser path in Vista
if (key == null)
{
key = Registry.CurrentUser.OpenSubKey(@"Software\Microsoft\Windows\Shell\Associations\UrlAssociations\http", false); ;
}
if (key != null)
{
//trim off quotes
browser = key.GetValue(null).ToString().ToLower().Replace("\"", "");
if (!browser.EndsWith("exe"))
{
//get rid of everything after the ".exe"
browser = browser.Substring(0, browser.LastIndexOf(".exe") + 4);
}
key.Close();
}
}
catch
{
return string.Empty;
}
return browser;
}
