Deserialize JSON string to c# object
提问by Shahbaz Chishty
My Application is in Asp.Net MVC3 coded in C#. This is what my requirement is. I want an object which is in the following format.This object should be achieved when I deserialize the Json string.
我的应用程序在用 C# 编码的 Asp.Net MVC3 中。这就是我的要求。我想要一个具有以下格式的对象。当我反序列化 Json 字符串时应该实现这个对象。
var obj1 = new { arg1=1,arg2=2 };
After using the below code:
使用以下代码后：
string str = "{\"Arg1\":\"Arg1Value\",\"Arg2\":\"Arg2Value\"}";
JavaScriptSerializer serializer1 = new JavaScriptSerializer();
object obje = serializer1.Deserialize<object>(str);
The object what i get i.e objedoes not acts as obj1
我得到的对象即obje不作为 obj1
Here, in this example my JSON string is static, but actually JSON string is going to be dynamically generated runtime, so i won't be able get Arg1 and Arg2 all the time.
在这里，在此示例中，我的 JSON 字符串是静态的，但实际上 JSON 字符串将是动态生成的运行时，因此我将无法始终获取 Arg1 和 Arg2。

I think the JavaScriptSerializer does not create a dynamic object.
我认为 JavaScriptSerializer 不会创建动态对象。
So you should define the class first:
所以你应该先定义类：
class MyObj {
public int arg1 {get;set;}
public int arg2 {get;set;}
}
And deserialize that instead of object:
并反序列化它而不是object：
serializer.Deserialize<MyObj>(str);
Not testet, please try.
不是testet，请尝试。

I believe you are looking for this:
我相信你正在寻找这个：
string str = "{\"Arg1\":\"Arg1Value\",\"Arg2\":\"Arg2Value\"}";
JavaScriptSerializer serializer1 = new JavaScriptSerializer();
object obje = serializer1.Deserialize(str, obj1.GetType());

Same problem happened to me. So if the service returns the response as a JSON string you have to deserialize the string first, then you will be able to deserialize the object type from it properly:
同样的问题发生在我身上。因此，如果服务将响应作为 JSON 字符串返回，您必须先反序列化该字符串，然后您才能正确地反序列化对象类型：
string json= string.Empty;
using (var streamReader = new StreamReader(response.GetResponseStream(), true))
{
json= new JavaScriptSerializer().Deserialize<string>(streamReader.ReadToEnd());
}
//To deserialize to your object type...
MyType myType;
using (var memoryStream = new MemoryStream())
{
byte[] jsonBytes = Encoding.UTF8.GetBytes(@json);
memoryStream.Write(jsonBytes, 0, jsonBytes.Length);
memoryStream.Seek(0, SeekOrigin.Begin);
using (var jsonReader = JsonReaderWriterFactory.CreateJsonReader(memoryStream, Encoding.UTF8, XmlDictionaryReaderQuotas.Max, null))
{
var serializer = new DataContractJsonSerializer(typeof(MyType));
myType = (MyType)serializer.ReadObject(jsonReader);
}
}
4 Sure it will work.... ;)
4 当然它会起作用....;)

This may be useful:
这可能很有用：
var serializer = new JavaScriptSerializer();
dynamic jsonObject = serializer.Deserialize<dynamic>(json);
Where "json" is the string that contains the JSON values. Then to retrieve the values from the jsonObject you may use
其中“json”是包含 JSON 值的字符串。然后从您可以使用的 jsonObject 中检索值
myProperty = Convert.MyPropertyType(jsonObject["myProperty"]);
Changing MyPropertyType to the proper type (ToInt32, ToString, ToBoolean, etc).
将 MyPropertyType 更改为正确的类型（ToInt32、ToString、ToBoolean 等）。

Use this code:
使用此代码：
var result=JsonConvert.DeserializeObject<List<yourObj>>(jsonString);
回答by sachin
solution :
解决方案 ：
public Response Get(string jsonData) {
var json = JsonConvert.DeserializeObject<modelname>(jsonData);
var data = StoredProcedure.procedureName(json.Parameter, json.Parameter, json.Parameter, json.Parameter);
return data;
}
model:
模型：
public class modelname {
public long parameter{ get; set; }
public int parameter{ get; set; }
public int parameter{ get; set; }
public string parameter{ get; set; }
}
