[英]Deserialize JSON string to c# object
My Application is in Asp.Net MVC3 coded in C#. 我的应用程序是在用C#编码的Asp.Net MVC3中。 This is what my requirement is. 这就是我的要求。 I want an object which is in the following format.This object should be achieved when I deserialize the Json string. 我想要一个以下格式的对象。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 ie obje does 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. 在这个示例中,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,因此我无法一直获得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: 所以你应该首先定义类:
class MyObj {
public int arg1 {get;set;}
public int arg2 {get;set;}
}
And deserialize that instead of object
: 并反序列化而不是object
:
serializer.Deserialize<MyObj>(str);
Not testet, please try. 不是测试,请尝试。
I believe you are looking for this: 我相信你在寻找这个:
string str = "{\"Arg1\":\"Arg1Value\",\"Arg2\":\"Arg2Value\"}";
JavaScriptSerializer serializer1 = new JavaScriptSerializer();
object obje = serializer1.Deserialize(str, obj1.GetType());
使用此代码:
var result=JsonConvert.DeserializeObject<List<yourObj>>(jsonString);
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. 其中“json”是包含JSON值的字符串。 Then to retrieve the values from the jsonObject you may use 然后从您可能使用的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)。
Same problem happened to me. 同样的问题发生在我身上。 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: 因此,如果服务将响应作为JSON字符串返回,则必须首先对字符串进行反序列化,然后您可以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当然可以工作......;)
solution : 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; }
}
