将JSON对象解析为列表

Question

当我尝试使用httpwebrequest而不是webclient解析JSON结果时遇到了问题（因为webcleint无法使用webservice cookie），请帮助我解析它，因为它的结果很复杂。

JSON结果为：

{"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对结果进行反序列化

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);
