Question

当我尝试使用httpwebrequest而不是webclient解析JSON结果时遇到问题（因为webcleint不使用webservice cookie），请帮我解析它，因为它的结果非常复杂。

JSON结果是：

{"d":"[{\"RefSymbol\":1,\"SymbolFactor\":100000,\"PriceCase\":1,\"RefPriceCase\":1,\"ID\":57,\"Type\":1,\"Name\":\"EUR\/CHF\",\"Bid\":1.2194,\"Ask\":1.2214,\"High\":1.2215,\"Low\":1.2185,\"LastQuoteTime\":\"24\/04\/2014 18:18:30\",\"SpreadOffset\":0,\"PriceOffset\":0,\"SpreadType\":\"1\",\"StopTradeIfNoPrices\":true,\"StopTradeAfterSeconds\":40,\"MaxAmountPerDeal\":10,\"MinAmountPerDeal\":1,\"AskWithSpread\":1.2214,\"BidWithSpread\":1.2194,\"Commission\":50,\"LimitOffset\":0,\"StopOffset\":0,\"PipLocation\":-4,\"Spread\":20,\"IsUsed\":true,\"IsDisplay\":false,\"HasPriv\":true,\"JustClose\":false,\"BuyOnly\":false},{\"RefSymbol\":1,\"SymbolFactor\":1000,\"PriceCase\":1,\"RefPriceCase\":1,\"ID\":58,\"Type\":1,\"Name\":\"EUR\/JPY\",\"Bid\":141.41,\"Ask\":141.46,\"High\":141.79,\"Low\":141.04,\"LastQuoteTime\":\"24\/04\/2014 18:18:35\",\"SpreadOffset\":0,\"PriceOffset\":0,\"SpreadType\":\"1\",\"StopTradeIfNoPrices\":true,\"StopTradeAfterSeconds\":40,\"MaxAmountPerDeal\":100,\"MinAmountPerDeal\":10,\"AskWithSpread\":141.46,\"BidWithSpread\":141.41,\"Commission\":50,\"LimitOffset\":0,\"StopOffset\":0,\"PipLocation\":-2,\"Spread\":5,\"IsUsed\":true,\"IsDisplay\":false,\"HasPriv\":true,\"JustClose\":false,\"BuyOnly\":false},
....

private void FireRequest2()
{
    var request = HttpWebRequest.Create(new Uri("http://xx.xx.xx.xx/mywebservice/")) as HttpWebRequest;
    request.Method = "GET";
    request.CookieContainer = cookieJar;
    request.BeginGetResponse(ar =>
    {
        HttpWebRequest req2 = (HttpWebRequest)ar.AsyncState;
        var response = (HttpWebResponse)req2.EndGetResponse(ar);
        int numVisibleCookies = response.Cookies.Count;
        RootObject root = JsonConvert.DeserializeObject<RootObject>(response);

    }, request);
}

首先，使用Json2cSharp.com创建您的类

public class Result
{
    public int RefSymbol { get; set; }
    public int SymbolFactor { get; set; }
    public int PriceCase { get; set; }
    public int RefPriceCase { get; set; }
    public int ID { get; set; }
    public int Type { get; set; }
    public string Name { get; set; }
    public double Bid { get; set; }
    public double Ask { get; set; }
    public double High { get; set; }
    public double Low { get; set; }
    public string LastQuoteTime { get; set; }
    public int SpreadOffset { get; set; }
    public int PriceOffset { get; set; }
    public string SpreadType { get; set; }
    public bool StopTradeIfNoPrices { get; set; }
    public int StopTradeAfterSeconds { get; set; }
    public int MaxAmountPerDeal { get; set; }
    public double MinAmountPerDeal { get; set; }
    public double AskWithSpread { get; set; }
    public double BidWithSpread { get; set; }
    public int Commission { get; set; }
    public int LimitOffset { get; set; }
    public int StopOffset { get; set; }
    public int PipLocation { get; set; }
    public object Spread { get; set; }
    public bool IsUsed { get; set; }
    public bool IsDisplay { get; set; }
    public bool HasPriv { get; set; }
    public bool JustClose { get; set; }
    public bool BuyOnly { get; set; }
}

public class RootObject
{
    public List<Result> result { get; set; }
}

然后使用JSON.NET反序列化结果

var request = HttpWebRequest.Create(new Uri("http://xx.xx.xx.xx/mywebservice/")) as HttpWebRequest;
request.Method = "GET";
request.CookieContainer = cookieJar;
request.BeginGetResponse(ar =>
{
    HttpWebRequest req2 = (HttpWebRequest)ar.AsyncState;
    using (var response = (HttpWebResponse) req2.EndGetResponse(ar))
    {
        using (Stream stream = response.GetResponseStream())
        {
            using (var reader = new StreamReader(stream))
            {
                RootObject root = JsonConvert.DeserializeObject<RootObject>(reader.ReadToEnd());
            }
        }

    }

}, request);

将JSON对象解析为List
