Bind json that has list of object to a model

Question

I want to bind this json:

{

        "DataPeriodId": 1,
        "MarketerId": 2,
        "MarketerTitle": "mehrdad",
        "CreditValues": [
            {
                "Title": "twelve",
                "CreditTypeId": 1,
                "Value": 2500000,
                "CreditId": 3,
                "HasMax": true
            },
            {
                "Title": "test",
                "CreditTypeId": 2,
                "Value": "",
                "CreditId": "",
                "HasMax": true
            },
            {
                "Title": "pouya",
                "CreditTypeId": 3,
                "Value": 1564564,
                "CreditId": 7,
                "HasMax": false
            },
            {
                "Title": "jafar",
                "CreditTypeId": 4,
                "Value": 0,
                "CreditId": 9,
                "HasMax": false
            },
            {
                "Title": "saeed",
                "CreditTypeId": 5,
                "Value": 0,
                "CreditId": 10,
                "HasMax": false
            }
        ]

}

To this object:

public class MarketerCredit
{
    public int DataPeriodId;
    public int MarketerId;
    public string MarketerTitle;
    public List<CreditValue> CreditValues;
}
public class CreditValue
{
    public int CreditId;
    public int CreditTypeId;
    public decimal? Value;
    public bool HasMax;
}

in mvc.net.

But when pass the json to action all member is null. This is my action:

   public void EditMarketerCredit(MarketerCredit marketerCredit)
        {


        }   

So i write this:

public void EditMarketerCredit(List<CreditValue> CreditValues,int DataPeriodId,int MarketerId,string MarketerTitle)

When separate the members all thing is ok. How can i bind the json to model?

Answer 1

You should add get and set for property:

public int DataPeriodId{get;set}

You added write just

public int DataPeriodId

And Mvc can not bind.

Answer 2

According to your json, you need a root object encapsulating MarketerCredit

public class RootObject
{
    public MarketerCredit MarketerCredit { set; get; }
}

BTW: your json contains a line "CreditId": "",, So type of CreditId should be string

Answer 3

You will need to implement your own custom model binder and then register it when the application starts. Here's a walkthrough explaining how to achieve this.

But, if you want to avoid customizing the MVC Pipeline you will need to create a new class/model that exposes a property called marketerCredit of type MarketerCredit, you can name this model whatever you like

public class MyModel
{
    public MarketerCredit marketerCredit{get;set;}
}

then modify your action method like this...

public void EditMarketerCredit(MyModel myModel)
{
}
