範例

下列範例程式碼示範使用 HttpMediaTypeWithQualityHeaderValueCollection 和HttpMediaTypeWithQualityHeaderValue類別的屬性和方法,取得和設定HttpRequestMessage物件上的Accept HTTP 標頭的方法。

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

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

            // Set the header with a string.
            parsedOk = request.Headers.Accept.TryParseAdd ("audio/*");
            parsedOk = request.Headers.Accept.TryParseAdd ("audio/*; q=0.2");
            parsedOk = request.Headers.Accept.TryParseAdd ("audio/*; q=0.4; mysetting=myvalue");

            // Set the header with a strong type.
            request.Headers.Accept.Add(new HttpMediaTypeWithQualityHeaderValue("audio/*", .6));

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

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

備註

HttpMediaTypeWithQualityHeaderValueCollection 代表 HTTP 要求上 Accept HTTP 標頭的值。

HttpMediaTypeWithQualityHeaderValueCollection 是 HttpMediaTypeWithQualityHeaderValue 物件的集合,用於接受 HTTP Accept 標頭中的資訊。

HttpRequestHeaderCollection上的Accept屬性會傳回 HttpMediaTypeWithQualityHeaderValueCollection 物件。
