如何在asp.net中反序列化json

本文关键字：反序列化 json net asp | 更新日期: 2023-09-27 18:06:39

我有来自web 的以下请求代码

StringBuilder sb = new StringBuilder();
byte[] buf = new byte[8192];
HttpWebRequest request = (HttpWebRequest)WebRequest.Create("http://api.bigflix.com/BIGFlixApi.do?parameter=getProductType&partnerID=17&uniqueID=54325345435&timestamp=131286916367&digest=bf53cae8f364cfc1d796489d09e4cfd&nbsp&nbsp<br>");
HttpWebResponse responce = (HttpWebResponse)request.GetResponse();
Stream resstream = responce.GetResponseStream();
string tempString = null;
int count = 0;
do
{
    count = resstream.Read(buf, 0, buf.Length);
    if (count != 0)
    {
        tempString = Encoding.ASCII.GetString(buf, 0, count);
        sb.Append(tempString);
    }
}
while (count > 0);
{
    Response.Write(sb.ToString() + "<br/><br/>");
    // string[] val = sb.ToString().Split('"');
}

运行此代码后，我将获得这种类型的json

[
    { "id": 23, "name": "Video Clips" }, 
    { "id": 15, "name": "Deleted Scenes" }, 
    { "id": 9, "name": "Music Albums" }, 
    { "id": 7, "name": "Trailers" }, 
    { "id": 18, "name": "Short Films" }, 
    { "id": 21, "name": "Movie Clips" }, 
    { "id": 1, "name": "Movies " }, 
    { "id": 4, "name": "Plays" }, 
    { "id": 22, "name": "Scenes" }, 
    { "id": 2,  "name": "TV Show" }, 
    { "id": 5, "name": "Kids" }, 
    { "id": 16, "name": "Interviews" }, 
    { "id": 11, "name": "Film Songs" }, 
    { "id": 14, "name": "Making of Movie" }
]

现在我想在asp.net(c#(中反序列化它
我试图得到一个恰当的答案，但没有得到。

请提供建议。

如何在asp.net中反序列化json

创建一个名为FromFlix的类inseide App_Code，如下

public class FromFlix
{
    public string ID { get; set; }
    public string Name { get; set; }
}

现在，在while循环结束后，执行此操作。

JavaScriptSerializer ser = new JavaScriptSerializer();
var response = ser.Deserialize<IList<FromFlix>>(sb.ToString());

response是List<FromFlix>，即FromFlix类型的泛型列表
这就是你应该如何使用它。

StringBuilder sb = new StringBuilder();
byte[] buf = new byte[8192];
HttpWebRequest request = (HttpWebRequest)WebRequest.Create("http://api.bigflix.com/BIGFlixApi.do?parameter=getProductType&partnerID=17&uniqueID=54325345435&timestamp=131286916367&digest=bf53cae8f364cfc1d796489d09e4cfd&nbsp&nbsp<br>");
HttpWebResponse responce = (HttpWebResponse)request.GetResponse();
Stream resstream = responce.GetResponseStream();
string tempString = null;
int count = 0;
do
{
    count = resstream.Read(buf, 0, buf.Length);
    if (count != 0)
    {
        tempString = Encoding.ASCII.GetString(buf, 0, count);
        sb.Append(tempString);
    }
}
while (count > 0);
JavaScriptSerializer ser = new JavaScriptSerializer();
List<FromFlix> response = ser.Deserialize<List<FromFlix>>(sb.ToString());
foreach (var item in response)
{
    Response.Write("ID: " + item.ID + "&" + "Name: " + item.Name + "<br/>");
}

希望这能有所帮助。

您可以使用JavaScriptSerializer类型来序列化和反序列化JSON数据。

var serializer = new JavaScriptSerializer();
var deserialized = serializer.Deserialize<TheTypeToWhichJSONWillMap>(myJson);

编辑：

我不确定您在这方面遇到了什么问题，但下面是您提供的JSON字符串的一个工作示例：

static string TheJson = "...";
public class TheType
{
    public int id { get; set;}
    public string name { get; set; }
}
var serializer = new JavaScriptSerializer();
var deserialized = serializer.Deserialize<List<TheType>>(TheJson);

这使得deserialized是具有14个元素的List<TheType>。
