简介:

C#

private  void OpenUrl( string url)
{
     string browser = GetDefaultBrowser();
     if ( browser.Length > 0 )
     {
        ProcessStartInfo psi = new ProcessStartInfo();
        psi.UseShellExecute =  false;
        psi.Arguments = url;
        psi.FileName = browser;
        System.Diagnostics.Process.Start(psi);
    }
     else
     {
        System.Diagnostics.Process.Start(url);
    }
}

private string GetDefaultBrowser()
{
     string browser = String.Empty;
    RegistryKey key =  null;
     try
     {
        key = Registry.ClassesRoot.OpenSubKey(@"HTTP\shell\open\command",  false);
        browser = key.GetValue( null).ToString().ToLower().Replace("\"", "");
         if ( !browser.EndsWith(".exe") )
         {
            browser = browser.Substring(0, browser.LastIndexOf(".exe") + 4);
        }
    }
     catch
     {
         if ( key !=  null )
         {
            key.Close();
        }
    }
    return browser;
}


VB.NET

Private Sub OpenUrl( ByRef url As String )
    Dim browser As  String = GetDefaultBrowser()
     If browser.Length > 0  Then
        Dim psi  As ProcessStartInfo =  New ProcessStartInfo
        psi.UseShellExecute =  False
        psi.Arguments = url
        psi.FileName = browser
        System.Diagnostics.Process.Start(psi)
     Else
        System.Diagnostics.Process.Start(url)
     End  If
End Sub

Private  Function GetDefaultBrowser()
     Dim browser  As String =  String.Empty
     Dim key  As RegistryKey
     Try
        key = Registry.ClassesRoot.OpenSubKey("HTTP\shell\open\command",  False)
        browser = key.GetValue( Nothing).ToString().ToLower().Replace("""", "")
         If  Not browser.EndsWith(".exe")  Then
            browser = browser.Substring(0, browser.LastIndexOf(".exe") + 4)
         End  If
     Catch ex  As Exception
         If  Not key Is  Nothing Then
            key.Close()
         End  If
