从 Windows 窗体打开 URL

我试图提供一个从 Windows 窗体到我公司网站的链接。我想要良好的行为和启动使用用户的首选浏览器。

从 Windows 窗体应用程序在用户的默认浏览器中打开 URL 的最佳方式是什么？

using System.Diagnostics;


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

This approach has worked for me, but I could be missing something important.

This article will walk you through it.

Short answer:

ProcessStartInfo sInfo = new ProcessStartInfo("http://mysite.com/");
Process.Start(sInfo);

I like approach described here. It takes into account possible exceptions and delays when launching the browser.

For best practice make sure you don't just ignore the exception, but catch it and perform an appropriate action (for example notify user that opening the browser to navigate him to the url failed).

The above approach is perfect, I would like to recommend this approach to where you can pass your parameters.

Process mypr;
mypr = Process.Start("iexplore.exe", "pass the name of website");

Here is the best of both worlds:

Dim sInfo As New ProcessStartInfo("http://www.mysite.com")


Try
Process.Start(sInfo)
Catch ex As Exception
Process.Start("iexplore.exe", sInfo.FileName)
End Try

I found that the answer provided by Blorgbeard will fail when a desktop application is run on a Windows 8 device. To Camillo's point, you should attempt to open this with the user's default browser application, but if the browswer application is not assigned, an unhandled exception will be thrown.

I am posting this as the answer since it handles the exception while still attempting to open the link in the default browser.

For those getting a "Win32Exception: The System cannot find the file specified"

This should do the work:

ProcessStartInfo psInfo = new ProcessStartInfo
{
FileName = "https://www.google.com",
UseShellExecute = true
};
Process.Start(psInfo);

UseShellExecute is descriped further here

For me the issue was due to the .NET runtime as descriped here
