範例

下列範例程式碼示範使用 HttpConnectionOptionValueCollection 和HttpConnectionOptionHeaderValueCollection 和 HttpConnectionOptionHeaderValue類別的屬性和方法,取得及設定HttpRequestMessage物件上的Connection HTTP 標頭的方法。

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

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

            // Set the header with a string.
            parsedOk = request.Headers.Connection.TryParseAdd("close");

            // Set the header with a strong type.
            request.Headers.Connection.Add(new HttpConnectionOptionHeaderValue("cache-control"));

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

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

備註

HttpConnectionOptionHeaderValueCollection 代表 HTTP 要求上 連線 HTTP 標頭的值。

HttpConnectionOptionHeaderValueCollection 是 HttpConnectionOptionHeaderValue 物件的集合,用於 HTTP 連接 標頭上的連接資訊。

HttpRequestHeaderCollection上的Connection屬性會傳回 HttpConnectionOptionHeaderValueCollection 物件。

集合成員清單

針對 JavaScript,HttpConnectionOptionHeaderValueCollection 具有成員清單中顯示的成員。 此外,HttpConnectionOptionHeaderValueCollection 支援 Array.prototype 的成員,並使用索引來存取專案。

列舉 C# 或 Microsoft Visual Basic 中的集合

您可以在 C# 或 Microsoft Visual Basic 中逐一查看 HttpConnectionOptionHeaderValueCollection 物件。 在許多情況下,例如使用 foreach 語法,編譯器會為您執行此轉換,而且您不需要明確地轉換成 IEnumerable<HttpConnectionOptionHeaderValue> 。 如果您需要明確轉換,例如,如果您想要呼叫GetEnumerator,請使用HttpConnectionOptionHeaderValue條件約束將集合物件轉換成IEnumerable < T >
