c# classes 格式将json数据发送到android app

Question

我有四张桌子：

1)tblcategory-此表包含所有顶级和子类别

2)tblcatmapping-该表给出了类别映射。表示哪个类别位于哪个类别下

3)tblitem-此表包含所有菜单项

4)tblitemmapping-此表包含映射详细信息。表示哪些项目位于哪个类别下。

tbl类别快照：

tblcatmapping 快照：

tblitem 快照

tblitemapping 快照：

现在我想将整个数据以 json 格式发送到 android 应用程序。我准备了一个粗略的 json 示例，我想在其中发送数据。

我也可以考虑其他格式。我的主要动机是发送所有类别和项目数据，并具有从 tblcatmapping 和 tblitemmapping 描述的适当关系。

如果我理解你的问题是正确的，你想看看与你的 JSON 对应的 C# 的样子，如果是这样的话：

public class RootObject
{
    public string CATID { get; set; }
    public string CATNAME { get; set; }
    public string CATTYPE { get; set; }
    public string CATDESC { get; set; }
    public string CATIMGPATH { get; set; }
    public List<object> CATSUBCAT { get; set; }
    public List<object> CATITEM { get; set; }
    public List<object> CATTITEM { get; set; }
}
