对WebBrowser控件使用自定义设置

Question

I'm trying to build an c# application that uses the WebBrowser Control for, obviouly, webbrowsing. To enhance the security of the system, i'd like to set my own security settings. These are two of the settings i would like to set through the software:

1. Disable Download for certain file-extensions (*.exe)
2. Disable Cookies

I found, that the WebBrowser Class directly uses the settings from Internet Explorer. Is there any way to use own settings for a specific WebBrower or overide these settings (maybe just temporarely)?

I think the Question may be similar to this:
Overriding IE settings when embedding a WebBrowser control using IE9
(But i'm not sure... :)

EDIT: If I change the Cookie-Settings for Internet Explorer, they will be used for my WebBrowser-Control, right? Is it possible to change these global Settings via C#? Maybe this could be an easy solution for the Problem...

Answer 1

Unfortunately, it doesn't look like you can disable cookies, though you can clear them; however, when you do so, you will be clearing cookies for all IE instances on that PC (for that particular account). Here is a StackOverflow with more detail .

As far as controlling which files may be downloaded, you probably need to use some form of the FileIOPermission Class. Here is a StackOverflow expanding on that with an example in the answer .

Last, explore the MSDN documentation for the Webbrowser control class, and you might get closer to what you need.

Good Luck!

Answer 2

You can adjust which files that can be downloaded by using the Navigating event of a webbrowser...

For Example, in the "Navigating" event for your web browser control...

if (e.Url.ToString().EndsWith(".exe"))
{
    e.Cancel = true;
}
