Way 2:

JSON response:

{
  "Contract": {
    "CustomerId": "Customer 1",
    "Name"      : "Name 1"
  }
}

Below is the Response contract :

[DataContractAttribute] 
public class responceContract
{
    private Contract CustomerContract;

    [DataMemberAttribute('Contract'), 
    DataCollection(Types::Class, classStr(Contract)),
    AifCollectionTypeAttribute('_contractClass', Types::Class, classStr(Contract)),
    AifCollectionTypeAttribute('return', Types::Class, classStr(Contract))]
    public Contract parmContract(Contract _CustomerContract = CustomerContract)
    {    
       CustomerContract = _CustomerContract;
       return CustomerContract;
    }
}

JSON response:

{
  "Contract": [
    {
      "CustomerId": "Customer 1",
      "Name": "Name 1"
    },
    {
      "CustomerId": "Customer 2",
      "Name": "Name 2"
    }
  ]
}

Below is the Response contract :

[DataContractAttribute] 
public class responceContract
{
    private List    Customer;

    [DataMemberAttribute('Contract'),
    DataCollection(Types::Class, classStr(Customer Contract)),
    AifCollectionTypeAttribute('_contractClass', Types::Class, classStr(Customer Contract)),
    AifCollectionTypeAttribute('return', Types::Class, classStr(Customer Contract))]
    public List parmCustomer(List _contractClass = Customer)
    {
        Customer = _Customer;
        return Customer;
    }
}

Contract class:

private str    CustomerId; 
private str    Name; 

[DataMemberAttribute('CustomerId')] 
public Str parmCustomerId(Str _CustomerId = CustomerId)
{
    CustomerId = _CustomerId;

    return CustomerId;
} 

[DataMemberAttribute('Name')] 
public Str parmName(Str _Name = Name)
{
    Name = _Name;

    return Name;
}
