    public List<dynamic> Data = new List<dynamic>();
    public bool Success { set; get; }
    public GeneralResponseClass()
    {
        Date = DateTime.Now.ToString("dd/MM/yyyy HH:mm:ss");
    }
}

in my API Function i want to return the object

[HttpGet]
public GeneralResponseClass Get()
    {
        GeneralResponseClass generalResponseClass = new GeneralResponseClass();

        generalResponseClass.ErrorCode = 0;
        generalResponseClass.ErrorMessage = "";


        generalResponseClass.Success = false;



        generalResponseClass.Data.Add(new
        {
            Name = "User 1",
            Email = "User1@user.com"
        });

        generalResponseClass.Data.Add(new
        {
            Name = "User 2",
            Email = "User2@user.com"
        });

        return generalResponseClass;
    }

in the response i get don't get the List

 {
   errorCode: 0,
date: "06/01/2020 16:32:12",
errorMessage: "",
success: false
}

Why The List Data dont return?

You cannot return any collection with anonymous object. You can use ExpandoObject which is simillar to anonymous . You can also create a custom class for your type of object since they have the same properties in your case (at least in the template).

You can check for more on ExpandoObject here: What are the true benefits of ExpandoObject?
