Google Chrome无法使用Process.Start（）从应用程序打开

Question

I have written windows application in c# that opens website in default browser on label click event. My default browser is Google Chrome. So when I start my application and click on label, it fails to open website in Chrome. Chrome throws error "Failed to create data directory - Google Chrome cannot read and write to its data directory". I am using "System.Diagnostics.Process.Start" to start process.

One interesting thing is, when I close my application and reopen it. It sucessfully opens website in default Chrome browser. :)

I tried by using various options of Process.StartInfo but never succeed. Below is the method used to run website.

I am using Windows 8-64Bit and .Net Framework 4. Could you please help me on this.

Test1:

public static void RunWebClient()
{
    Process proc = new Process();

    Microsoft.Win32.RegistryKey subKey = Microsoft.Win32.Registry.ClassesRoot.OpenSubKey(@"http\shell\open\command");
    String DefaultBrowser = subKey.GetValue(null).ToString();

    if (DefaultBrowser != null)
    {
        int startIndex = DefaultBrowser.IndexOf("\"") + 1;
        int endIndex = DefaultBrowser.IndexOf("\"", startIndex);
        string RegDefaultBrowserPath = DefaultBrowser.Substring(startIndex, endIndex - startIndex);

        proc.StartInfo.FileName = RegDefaultBrowserPath;
        proc.StartInfo.Arguments = @"http://localhost/Test/";
        proc.StartInfo.UseShellExecute = true;
        proc.StartInfo.LoadUserProfile = false;
        proc.Start();
    }
}

Test2:

public static void RunWebClient()
{
    System.Diagnostics.Process.Start("http://localhost/Test/");
}

I would try to add the WorkingDirectory to your ProcessStartInfo class

proc.StartInfo.FileName = Path.GetFileName(RegDefaultBrowserPath);
proc.StartInfo.WorkingDirectory = Path.GetDirectoryName(RegDefaultBrowserPath);

Passing the full file name into the FileName property is not enough to set the current working directory for the launched file.
