c# 序列化

对接过的接口中使用到的序列化，由DataSet序列化 Json，由DataTable序列化 Json分别产生怎样的 Json格式，以及如何将格式转换为接口提供方需要的正确格式。

下面简单记录下：

1、DataSet 转换为 Json （ds中有两个Table）：

string dsJson = JsonConvert.SerializeObject(ds);

得到的格式如下：

{
    "Table": [{
        "startProvinceName": "四川省",
        "startCityName": "成都市",
        "startAreaName": "",
        "endProvinceName": "湖北省",
        "endCityName": "武汉市",
        "endAreaName": "",
        "cargoName": "普货",
        "truckTypes": "厢车",
        "truckLength": 17.5,
        "lclCargo": "0",
        "weight": 25.9,
        "capacity": 70.9,
        "loadMethod": 1,
        "loadTimeDay": "2019-05-10",
        "loadTimeSegment": 0,
        "unLoadTimeDay": "2019-05-11",
        "unLoadTimeSegment": 0,
        "description": "发布货源测试",
        "internalOrderId": "CD201805-0015",
        "dispatcherTelphone": "18855667799",
        "assignDriverTelphone": "",
        "createContractFlag": "false"
    }],
    "Table1": [{
        "preFreight": "",
        "arriveFreight": "",
        "receiptFreight": "",
        "daysForPayFreight": "",
        "contractLoadTime": "2019-05-10 18",
        "contractUnLoadTime": "2019-05-11 18",
        "note": ""
    }]
}

2、DataTable 转化为 Json (上面DataSet中的两个Table)

[{
    "startProvinceName": "浙江省",
    "startCityName": "宁波市",
    "startAreaName": "",
    "endProvinceName": "广东省",
    "endCityName": "深圳市",
    "endAreaName": "",
    "cargoName": "普货",
    "truckTypes": "厢车",
    "truckLength": 17.5,
    "lclCargo": "0",
    "weight": 1.0,
    "capacity": 1.0,
    "loadMethod": 1,
    "loadTimeDay": "2019-05-10",
    "loadTimeSegment": 0,
    "unLoadTimeDay": "2019-05-11",
    "unLoadTimeSegment": 0,
    "description": "发布货源测试",
    "internalOrderId": "NB201805-0025",
    "dispatcherTelphone": "18855667799",
    "assignDriverTelphone": "",
    "createContractFlag": "false"
}]

[{
    "preFreight": "",
    "arriveFreight": "",
    "receiptFreight": "",
    "daysForPayFreight": "",
    "contractLoadTime": "2019-05-10 18",
    "contractUnLoadTime": "2019-05-11 18",
    "note": ""
}]

3、接口方需要的参数格式为：

{
    "startProvinceName": "江苏省",
    "startCityName": "南京市",
    "startAreaName": "建邺区",
    "endProvinceName": "江苏省",
    "endCityName": "南京市",
    "endAreaName": "秦淮区",
    "cargoName": "龙虾",
    "truckTypes": "冷藏",
    "truckLength": "12.2",
    "lclCargo": 0,
    "weight": "13.3",
    "capacity": "14.4",
    "loadMethod": 1,
    "loadTimeDay": "2019-05-22",
    "loadTimeSegment": 4,
    "unLoadTimeDay": "2019-05-24",
    "unLoadTimeSegment": 4,
    "description": "小龙虾不要太好吃哇！",
    "internalOrderId": "111111111",
    "dispatcherTelphone": "17722221234",
    "assignDriverTelphone": "{{assignDriverTelphone}}",
    "createContractFlag": true,
    "createContractParam": {
        "preFreight": 1111,
        "arriveFreight": 3333,
        "receiptFreight": 7777,
        "daysForPayFreight": 0,
        "contractLoadTime": "2019-05-22 12",
        "contractUnLoadTime": "2019-05-24 12",
        "note": "靠谱老司机哇哇哇"
    }
}

因此需要将DataSet 转换得到的格式 再进行下一步的转换，使用下面的方法：

先将DataSet中的第二个Table名称改为：createContractParam   

ds.Tables[1].TableName = "createContractParam";

//下面进行转换：
json = JsonConvert.SerializeObject(ds).Replace(""Table":[{", "").Replace("}],", ",").Replace("[", "").Replace("]", "");

///以上就得到了对方提供的接口参数的格式
