api接口响应类型定义

public class Response<T>
{
    public ResponseStatus Status { get; set; }
    public string Message { get; set; }
    public T ResponseData { get; set; }
    public string Token { get; set; }
}

public enum ResponseStatus
{
    正常 = 200,
    不正常 = 300
}

public class ResponseData<T, S> where T : struct
{
    public T Status { get; set; }

    public S Data { get; set; }
}

public enum DataStatus
{
    购买成功 = 200,
    订单数量超过库存数量 = 300
}

使用

Response<ResponseData<DataStatus, List<string>>>
