WinRT 中的 HttpUtility.ParseQueryString 方法在哪里？

Since Http实用程序 http://msdn.microsoft.com/en-us/library/system.web.httputility.aspx在 WinRT 中不可用，我想知道是否有一种简单的方法来解析 HTTP 查询字符串？

实际上有一些相当于HttpUtility.ParseQueryString http://msdn.microsoft.com/en-gb/library/system.web.httputility.parsequerystring.aspx在 WinRT 中？

代替HttpUtility.ParseQueryString您可以使用WwwFormUrlDecoder http://msdn.microsoft.com/en-us/library/windows/apps/hh825884.aspx.

这是我抓住的一个例子here http://www.dzhang.com/blog/2012/08/21/parsing-uri-query-strings-in-windows-8-metro-style-apps

using System;
using Microsoft.VisualStudio.TestPlatform.UnitTestFramework;
using Windows.Foundation;

[TestClass]
public class Tests
{
    [TestMethod]
    public void TestWwwFormUrlDecoder()
    {
        Uri uri = new Uri("http://example.com/?a=foo&b=bar&c=baz");
        WwwFormUrlDecoder decoder = new WwwFormUrlDecoder(uri.Query);

        // named parameters
        Assert.AreEqual("foo", decoder.GetFirstValueByName("a"));

        // named parameter that doesn't exist
        Assert.ThrowsException<ArgumentException>(() => {
            decoder.GetFirstValueByName("not_present");
        });

        // number of parameters
        Assert.AreEqual(3, decoder.Count);

        // ordered parameters
        Assert.AreEqual("b", decoder[1].Name);
        Assert.AreEqual("bar", decoder[1].Value);

        // ordered parameter that doesn't exist
        Assert.ThrowsException<ArgumentException>(() => {
            IWwwFormUrlDecoderEntry notPresent = decoder[3];
        });
    }
}
