HttpProductInfoHeaderValueCollection HttpProductInfoHeaderValueCollection HttpProductInfoHeaderValueCollection HttpProductInfoHeaderValueCollection Class

Represents the value of the User-Agent HTTP header on an HTTP request.

Syntax

Declaration

public sealed class HttpProductInfoHeaderValueCollectionpublic sealed class HttpProductInfoHeaderValueCollectionPublic NotInheritable Class HttpProductInfoHeaderValueCollection

Remarks

The HttpProductInfoHeaderValueCollection represents the value of the User-Agent HTTP header on an HTTP request.

The HttpProductInfoHeaderValueCollection is a collection of HttpProductInfoHeaderValue objects used for product information in the HTTP User-Agent header.

The User-Agent header contains information about the user agent originating the request. The User-Agent header can contain multiple product tokens and comments identifying the user agent and any sub-products.

The UserAgent property on the HttpRequestHeaderCollection returns an HttpProductInfoHeaderValueCollection object.

Examples

The following sample code shows a method to get and set the User-Agent HTTP header on an HttpRequestMessage object using the properties and methods on the HttpProductInfoHeaderValueCollection and HttpProductInfoHeaderValue classes.


using System;
using Windows.Web.Http;
using Windows.Web.Http.Headers;

        public void DemonstrateHeaderRequestUserAgent() {
            var request = new HttpRequestMessage();
            bool parsedOk = false;

            // Set the header with a string.
            parsedOk = request.Headers.UserAgent.TryParseAdd("testprogram/1.0");

            // Set the header with a strong type.
            request.Headers.UserAgent.Add(new HttpProductInfoHeaderValue("myprogram", "2.2"));

            // Get the strong type out 
            foreach (var value in request.Headers.UserAgent) {
                System.Diagnostics.Debug.WriteLine("One of the UserAgent values: {0} / {1}", value.Product.Name, value.Product.Version);
            }

            // The ToString() is useful for diagnostics, too.
            System.Diagnostics.Debug.WriteLine("The UserAgent ToString() results: {0}", request.Headers.UserAgent.ToString());
        }
