Question

insert into table1(LearnerTelephones_ID,LearnerTelephones_IsFirst,LearnerTelephones_L_ID , LearnerTelephones_Ln_IDNAME,
LearnerTelephones_Ln_IDAdd,LearnerTelephones_Notes,LearnerTelephones_TelephoneNumber,LearnerTelephones_UseForText)
values(,,,,,,..)

我的数据表如上所述，它有破坏行 - startrow和endrow。我想从这个数据表中创建插入语句，对于前者

{{1}}

所以我需要创建4个插入语句。

Answer 1

您应该首先编写一些对反序列化json字符串有用的类。

class LearnerTelephones
{
    public string ID { get; set; }
    public bool IsFirstPointOfContact { get; set; }
    public LocationType LocationType { get; set; }
    public string Notes { get; set; }
    public string TelephoneNumber { get; set; }
    public bool UseForTextMessages { get; set; }
}

class LocationType
{
    public string ID { get; set; }
    public IList<NameType> NameType { get; set; }
}
class NameType
{
    public string IDNAME { get; set; }
    public string IDAdd { get; set; }
}

class RootObject
{
    public LearnerTelephones LearnerTelephones { get; set; }

}

然后将newton.json包安装到项目中（如果未安装）。 newton.json package link

然后，您可以轻松地将json字符串解析和反序列化为c＃对象并根据您的要求进行迭代，并可以创建插入语句。

class Program
{
    static void Main(string[] args)
    {



        string json = "{\"LearnerTelephones\":{ \"ID\": \"eaf32af9-07bf-4d87-8aeb-84ac8860dee9\", \"IsFirstPointOfContact\": true, \"LocationType\": { \"ID\": \"ebbbaa62-f1f0-4010-8b0b-ee744eafc1de\", \"NameType\":[{ \"IDNAME\": \"my name\", \"IDAdd\": \"my id address\" }, { \"IDNAME\": \"my name2\", \"IDAdd\": \"my id address2\" } ] }, \"Notes\": null, \"TelephoneNumber\": \"028 3282 3717\", \"UseForTextMessages\": true } }";
        RootObject obj = Newtonsoft.Json.JsonConvert.DeserializeObject<RootObject>(json);
        string sql = string.Empty;

        if (obj != null)
        {
            for (int i = 0; i < obj.LearnerTelephones.LocationType.NameType.Count; i++)
            {

                var obj1 = obj.LearnerTelephones;
                sql += string.Format("insert into table1(LearnerTelephones_ID,LearnerTelephones_IsFirst,LearnerTelephones_L_ID , LearnerTelephones_Ln_IDNAME, LearnerTelephones_Ln_IDAdd,LearnerTelephones_Notes,LearnerTelephones_TelephoneNumber,LearnerTelephones_UseForText) values " +
                                          "('{0}','{1}','{2}','{3}','{4}','{5}','{6}');", obj1.ID, obj1.IsFirstPointOfContact, obj1.LocationType.NameType[i].IDNAME, obj1.LocationType.NameType[i].IDAdd, obj1.Notes, obj1.TelephoneNumber, obj1.UseForTextMessages);
            }
        }

        Console.WriteLine(sql);
        Console.Read();
    }
}

我想这会很有用。并根据您的要求更新逻辑。
