如何将接口方法中的值返回到JSON对象？ [英] How can I return the values from the interface methods into a JSON object?

问题描述

我想将C＃类作为JSON对象返回：

I want to return a C# class as a JSON object:

这是我的开关代码：

 public IDatasource GetDataSource(DataSourceType type)
    {
        switch (type)
        {
            case DataSourceType.CONTROL:
                return new ControlDS();
            case DataSourceType.RISK:
                return new RiskDS();
            case DataSourceType.MOI:
                return new MoiDS();
            case DataSourceType.LOSSEVENTS:
                return new LossEventDS();
            case DataSourceType.KRI:
                return new KriDS();
            default:
                throw new ArgumentOutOfRangeException();
        }
    }

对于每种类型，它必须返回一个完整的类。我们假设类型是 KRI ，它必须返回类 KriDS 这是它的样子：

For each type it must return a whole class. Let's take for example type is KRI and it must return the class KriDS this is how it looks like:

 public class KriDS : IDatasource
    {
        public string Description()
        {
            var description = "This is a description";
            return description;
        }

        public string Name()
        {
            var kriname = "Test1";
            return kriname;
        }

        public int[] Values()
        {
            int[] values = new int[] { 1, 5, 7, 6, 7 };
            return values;
        }
    }

在我的控制器中，我使用以下方法：

And in my controller I use the following method:

[HttpGet]
    public string GetDataSource(string id)
    {
       // var type = (DataSourceType)id;
        DataSourceType type;
        if(!Enum.TryParse(id, out type))
        {
            throw new ArgumentOutOfRangeException();
        }
        var o = _dashboarBusiness.GetDataSource(type = DataSourceType.KRI);
        return Newtonsoft.Json.JsonConvert.SerializeObject(o);
    }

当我返回 var o 我想以此返回

{"description": "This is a description", "name": "Test1", "values": "[{1 5, 7, 6, 7}]"}

当我返回它时，对象为空。

When I return it the object is null.

如何将方法的值返回到JSON对象？

How can I return the values of the methods into a JSON object?

有人能指出我正确的方向吗？

Can someone point me in the right direction?

亲切的问候

推荐答案

而不是创建字段所需的方法/属性。方法可以填充这些。尝试使用此：

Instead of methods you need to create fields/properties. Methods can populate those. Try using this:

public class KriDS : IDatasource
{
    public string description = "This is a description";
    public string name = "Test1";
    public int[] values = new int[] { 1, 5, 7, 6, 7 };
}
