As others have indicated, Process.Start()is the way to go here. However, there are a few quirks. It's worth your time to read this blog post:
正如其他人所指出的那样，Process.Start()是去这里的方式。但是，有一些怪癖。值得您花时间阅读这篇博文：

In summary, some browsers cause it to throw an exception for no good reason, the function can block for a while on non-UI thread so you need to make sure it happens near the end of whatever other actions you might perform at the same time, and you might want to change the cursor appearance while waiting for the browser to open.
总之，某些浏览器会无缘无故地导致它抛出异常，该函数可能会在非 UI 线程上阻塞一段时间，因此您需要确保它在您可能同时执行的任何其他操作结束时发生，并且您可能希望在等待浏览器打开时更改光标外观。

This should work:
这应该有效：
Dim webAddress As String = "http://www.example.com/"
Process.Start(webAddress)

You can use Process.Start:
您可以使用Process.Start：
Dim url As String = “http://www.example.com“
Process.Start(url)
This should open whichever browser is set as default on the system.
这应该打开系统上设置为默认的浏览器。

Here is a little sub that may just interest some people who need to specify the browser. (but its not as good as a 12" pizza sub!) :P
这是一个小子，可能会让一些需要指定浏览器的人感兴趣。（但它不如 12 英寸的比萨饼好！）：P
Private Sub NavigateWebURL(ByVal URL As String, Optional browser As String = "default")
If Not (browser = "default") Then
Try
'// try set browser if there was an error (browser not installed)
Process.Start(browser, URL)
Catch ex As Exception
'// use default browser
Process.Start(URL)
End Try
Else
'// use default browser
Process.Start(URL)
End If
End Sub
Call: will open www.google.com in Firefox if it is installed on that PC.
调用：如果安装在该 PC 上，将在 Firefox 中打开 www.google.com。
NavigateWebURL("http://www.google.com", "Firefox") '// safari Firefox chrome etc
Call: will open www.google.com in default browser.
调用：将在默认浏览器中打开 www.google.com。
NavigateWebURL("http://www.google.com", "default")
OR
或者
NavigateWebURL("http://www.google.com")

This worked perfectly for me. Since this is for personal use, I used Firefox as my browser.
这对我来说非常有效。由于这是供个人使用，我使用 Firefox 作为我的浏览器。
Dim url As String
url = "http://www.google.com"
Process.Start("Firefox", url)
