示例
下面的示例代码演示了一个方法,该方法使用 HttpLanguageRangeWithQualityHeaderValueCollection 和 HttpLanguageRangeWithQualityHeaderValue 类的属性和方法获取和设置 HttpRequestMessage 对象上的 Accept-LanguageHTTP 标头。
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());
}
注解
HttpLanguageRangeWithQualityHeaderValueCollection 类表示 HTTP 请求上的 Accept-Language HTTP 标头的值。
HttpLanguageRangeWithQualityHeaderValueCollection 为 HttpLanguageRangeWithQualityHeaderValue 类的实例提供一个集合容器,该类用于接受 Accept-Language HTTP 标头中的语言信息。
HttpRequestHeaderCollection 上的 AcceptLanguage 属性返回 HttpLanguageRangeWithQualityHeaderValueCollection 对象。
