Examples

The following sample code shows a method to get and set the Accept-Language HTTP header on an HttpRequestMessage object using the properties and methods on the HttpLanguageRangeWithQualityHeaderValueCollection and HttpLanguageRangeWithQualityHeaderValue classes.

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

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

            // Set the header with a string.
            parsedOk = request.Headers.AcceptLanguage.TryParseAdd("da");
            parsedOk = request.Headers.AcceptLanguage.TryParseAdd("en-gb;q=0.8");

            // Set the header with a strong type.
            request.Headers.AcceptLanguage.Add(new HttpLanguageRangeWithQualityHeaderValue("en", .7));

            // Get the strong type out
            foreach (var value in request.Headers.AcceptLanguage) {
                System.Diagnostics.Debug.WriteLine("One of the AcceptLanguage values: {0}={1}", value.LanguageRange, value.Quality);
            }

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

Remarks

The HttpLanguageRangeWithQualityHeaderValueCollection class represents the value of the Accept-Language HTTP header on an HTTP request.

The HttpLanguageRangeWithQualityHeaderValueCollection provides a collection container for instances of the HttpLanguageRangeWithQualityHeaderValue class used for accept language information in the Accept-Language HTTP header.

The AcceptLanguage property on the HttpRequestHeaderCollection returns an HttpLanguageRangeWithQualityHeaderValueCollection object.
