Answer 1

You can use the HttpBrowserCapabilities in System.Web like this

        var userAgent = HttpContext.Current.Request.UserAgent;
        var userBrowser = new HttpBrowserCapabilities { Capabilities = new Hashtable { { string.Empty, userAgent } } };
        var factory = new BrowserCapabilitiesFactory();
        factory.ConfigureBrowserCapabilities(new NameValueCollection(), userBrowser);

        //Set User browser Properties
        BrowserBrand = userBrowser.Browser;
        BrowserVersion = userBrowser.Version;

This relies on browscap.ini in Windows/System32/inetsrv/ or Windows/SysWOW64/inetsrv for definitions.

You could do something like following too from within the Web API's action:

System.Net.Http.HttpRequestMessage currentRequest = this.Request;
System.Net.Http.Headers.HttpHeaderValueCollection<System.Net.Http.Headers.ProductInfoHeaderValue> userAgentHeader = currentRequest.Headers.UserAgent;
