javascript - 将多个 DataTable 序列化为 JSON

Question

我想将两个 DataTables 序列化为 JSON，但我做不到。我查看了示例，但无法解决问题。 请帮助我。

我的数据表:

    SqlDataAdapter adp1 = new SqlDataAdapter("select * from table1", con);
    SqlDataAdapter adp2 = new SqlDataAdapter("select * from table2", con);

    DataTable dt1 = new DataTable();
    DataTable dt2 = new DataTable();

    adp1.Fill(dt1);
    adp2.Fill(dt2);

我想得到这个结果:

var Json_Array = {
        "DataTable1":
            [
                {
                    "Id": "1",
                    "Name": "John"                       
                },
                {
                    "Id": "2",
                    "Name": "Mike"                        
                }
            ],
        "DataTable2":
            [
                {
                    "Mark": "Opel",
                    "Year": "1998"
                },
                {
                    "Mark": "Renault",
                    "Year": "2016"
                }
            ]
    };

只需将您的 DataTables 添加到匿名对象并使用 Json.Net 对其进行序列化:

var data = new
{
    DataTable1 = dt1,
    DataTable2 = dt2
};

string json = JsonConvert.SerializeObject(data, Formatting.Indented);
