Question

我的代码工作正常，但我不确定我采用的方法是否是最佳实践。所以，我决定在这个论坛上提问。

所以这是我的情况：

我的模型看起来像这样：

public class Member
{
    [Range(1, int.MaxValue)]
    public int? MemberID { get; set; }

    [Required]
    public List<MemberExperience> MemberExperiences { get; set; }

    [Required]
    public string MemberAddress { get; set; }

    [Required]
    public MemberInformation MemberInformation { get; set; }
}

public class MemberExperience
{
    [Required]
    [Range(1, int.MaxValue)]
    public int FromYear { get; set; }

    [Required]
    [Range(1, int.MaxValue)]
    public int ToYear { get; set; }

    [Required]
    public string CompanyAddress { get; set; }

    [Required]
    public string ProgrammingLanguage { get; set; }
}

public class MemberInformation
{
    [Required]
    public string FullName { get; set; }

    [Required]
    public DateTime BirthDate { get; set; }

    [Required]
    public string TelephoneNumber { get; set; }
}

从客户端来说，我传递给服务器的是这样的：

{
   "MemberExperiences": [
    {
        "FromYear": 2005,
        "ToYear": 2008,
        "CompanyAddress": "string",
        "ProgrammingLanguage": "Javascript"
    },
    {
        "FromYear": 2009,
        "ToYear": 2012,
        "CompanyAddress": "string",
        "ProgrammingLanguage": "C++"
    },
    {
        "FromYear": 2013,
        "ToYear": 2017,
        "CompanyAddress": "string",
        "ProgrammingLanguage": "C#"
    }
  ],
  "MemberAddress": "string",
  "MemberInformation": {
      "FullName": "string",
      "BirthDate": "1992-01-01",
      "TelephoneNumber": "string"
  }
}

然后我的控制器看起来像这样（我想从客户端传递的数据将转换为Member模型，其中包含所有数据）：

[HttpPost]
public HttpActionResult AddMember([FromBody] Member member)
{
      var response = AddMemberToDatabase(member);

      return Ok(response);
}

但是，因为我不知道Dapper（我使用Dapper与数据库进行通信）如何转换映射变量（在本例中为MemberExperience和{{ 1}}）成单个对象并被识别。所以，我所做的就是这样：

获取所有成员数据，但在将其插入数据库之前，我将创建一个存储来自MemberInformation和MemberExperience的数据列表的类。
将所有数据加入1个单长字符串中，并用分隔符分隔，只有数据库才允许访问它并知道它。

SingleMember 类：

MemberInformation

AddMemberToDatabase 功能：

public class SingleMember
{
    public int? MemberID { get; set; }
    public string FromYears { get; set; }
    public string ToYears { get; set; }
    public string CompanyAddresses { get; set; }
    public string ProgrammingLanguages { get; set; }
    public string MemberAddress { get; set; }
    public string FullName { get; set; }
    public DateTime BirthDate { get; set; }
    public string TelephoneNumber { get; set; }
}

然后，从private int AddMemberToDatabase(Member members) { var separator = "$Format"; var singleMember = new SingleMember { FromYears = string.Join(separator, members.MemberExperiences.Select(x => x.FromYear)), ToYears = string.Join(separator, members.MemberExperiences.Select(x => x.ToYear)), CompanyAddresses = string.Join(separator, members.MemberExperiences.Select(x => x.CompanyAddress)), ProgrammingLanguages = string.Join(separator, members.MemberExperiences.Select(x => x.ProgrammingLanguage)), MemberAddress = members.MemberAddress; FullName = members.MemberInformation.FullName; BirthDate = members.MemberInformation.BirthDate; TelephoneNumber = members.MemberInformation.TelephoneNumber; }; using (TransactionScope trans = new TransactionScope()) using (IDbConnection conn = new SqlConnection("MyConnection")) { conn.Open(); int rowsAffected = conn.Execute("MyStoredProcedure", singleMember); trans.Complete(); return rowsAffected; } }开始，它将按照定义的格式MyStoredProcedure拆分连接的数据，并将其按1插入到表1中，直到被拆分的项目不再被拆分

$Format

有没有更好的方法呢？

你的回答非常感谢。

我认为为CRUD操作创建存储过程效果不佳。如果您有很多表，请在您的应用程序中创建c＃支持以生成SQL命令（插入，更新，删除），并将它们作为带有参数的SqlCommand（事务处理器）发送到数据库中。

将映射模型数据插入或更新到数据库中
