Process.Start(url) broken on Windows 8/Chrome - are there alternatives?

阅读更多关于 Process.Start(url) broken on Windows 8/Chrome - are there alternatives?

问题 To open a URL from a .NET application, many sites (including on StackOverflow) cite this example: Process.Start("http://www.google.com/"); On Windows 8, this works if Internet Explorer is the default browser.
