範例
下列範例程式碼示範方法,使用HttpContentCodingWithQualityHeaderValueCollection 和 HttpContentCodingWithQualityHeaderValueCollection 和 HttpContentCodingWithQualityHeaderValue類別上的屬性和方法,在HttpRequestMessage物件上取得和設定Accept-Encoding HTTP 標頭。
using Windows.Web.Http;
using Windows.Web.Http.Headers;
public void DemonstrateHeaderRequestAcceptEncoding()
{
var request = new HttpRequestMessage();
bool parsedOk = false;
// Set the header with a string.
parsedOk = request.Headers.AcceptEncoding.TryParseAdd("compress");
parsedOk = request.Headers.AcceptEncoding.TryParseAdd("gzip;q=1.0");
// Set the header with a strong type.
request.Headers.AcceptEncoding.Add(new HttpContentCodingWithQualityHeaderValue("*", 0));
// Get the strong type out
foreach (var value in request.Headers.AcceptEncoding)
{
System.Diagnostics.Debug.WriteLine("One of the AcceptEncoding values: {0}={1}", value.ContentCoding, value.Quality);
}
// The ToString() is useful for diagnostics, too.
System.Diagnostics.Debug.WriteLine("The AcceptEncoding ToString() results: {0}", request.Headers.AcceptEncoding.ToString());
}
備註
HttpContentCodingWithQualityHeaderValueCollection 類別代表 HTTP 要求上 Accept-Encoding HTTP 標頭的值。
HttpContentCodingWithQualityHeaderValueCollection 提供 HttpContentCodingWithQualityHeaderValue 類別的集合容器,用於接受 Accept-Encoding HTTP 標頭中的編碼資訊。
HttpRequestHeaderCollection上的AcceptEncoding屬性會傳回 HttpContentCodingWithQualityHeaderValueCollection 物件。 這是用來建構 HttpContentCodingWithQualityHeaderValueCollection 物件的方法。
集合成員清單
針對 JavaScript,HttpContentCodingWithQualityHeaderValueCollection 具有成員清單中顯示的成員。 此外,HttpContentCodingWithQualityHeaderValueCollection 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 HttpContentCodingWithQualityHeaderValueCollection 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<HttpContentCodingWithQualityHeaderValue>
。 如果您需要明確轉換,例如,如果您想要呼叫GetEnumerator,請使用HttpContentCodingWithQualityHeaderValue條件約束將集合物件轉換成IEnumerable < T >。
