Does HttpBrowserCapa bilities work?

Robert W.

I just added this line of code to a simple aspx page:

HttpBrowserCapa bilities browserCap = new HttpBrowserCapa bilities();

Yet when I used QuickWatch in Debug mode to inspect 'browserCap' all the
properties were null. How come?

Try this :

HttpBrowserCapa bilities bc = Request.Browser ;
Response.Write( "Browser Capabilities:");
Response.Write( "Type = " + bc.Type + " ");
Response.Write( "Name = " + bc.Browser + " ");
Response.Write( "Version = " + bc.Version + " ");
Response.Write( "Major Version = " + bc.MajorVersion + " ");
Response.Write( "Minor Version = " + bc.MinorVersion + " ");
Response.Write( "Platform = " + bc.Platform + " ");
Response.Write( "Is Beta = " + bc.Beta + " ");

Oh I see, it's a data structure, not a [populated] object in and of itself.

just remember, browsercaps just looks at the UserAgent string sent by the
browser, and lookups the values based on the string, so the browsercaps
values are not alway accurate. for example, JavaScript is true for IE, but
the user may have javascript disabled. also some browser (say opera) lie
about who they are.

re:

Unfortunately, the userAgent string is the *only* way to identify browsers.

If someone comes to my site while spoofing their userAgent,
they deserve whatever rendering problems they get.
