asp.net - 使用列表将文本框中的多个值插入数据库

Question

这是所需的图像，我想通过此页面中的提交按钮通过姓名、员工代码和电子邮件 ID 插入多个值。
我的数据库包含以下字段 ID（主键）、姓名（varchar 50）、员工代码（varchar 50）、电子邮件 ID（varchar 50）。

在数据层，我的代码如下：

public static bool AddParticipantlistemployeecode(DimensionQuestion dimension)
   {
       bool result;


       using (var helper = new DbHelper())
       {
           _cmdtext = "sp_NewGeneratedUniqueCode";

           var success = new SqlParameter("@Success", SqlDbType.Bit, 1,    ParameterDirection.Output, true, 0, 0,
                                          "Result", DataRowVersion.Default, 0);

           foreach (string s in dimension.CandidateName)
           {
               if (s.Trim().Length > 0)
               {
                   var parameter = new[]
                                {
                                   // new   SqlParameter("@CompanyName",dimension.CompanyName  ),
                                    new SqlParameter("@CandidateName",s  ),
                                    new SqlParameter("@EmployeeCode",s  ),
                                    new SqlParameter("@EmailId",s  ),                                                                             
                                    success,
                                };
                   helper.ExecuteScalar(_cmdtext, CommandType.StoredProcedure, parameter);
               }
           }

           result = (bool)success.Value;
       }


       return result;
   }

在模型层：

using System.Text;
using System.Collections.Generic;
namespace Cengrow.Survey.Core.Model
{
public class DimensionQuestion
{
    public string CompanyName { get; set; }
   // public string DimensionNumber { get; set; }
    public List<string> CandidateName { get; set; }
    public List<string> EmployeeCode { get; set; }
    public List<string> EmailId { get; set; }
    public int DimensionName { get; set; }
    public string Section { get; set; }
    //public string Rating { get; set; }
    public List<string> Questions { get; set; }
    //public string Question2 { get; set; }
    //public string Question3 { get; set; }
    //public string Question4 { get; set; }
    //public string Question5 { get; set; }
    //public string Question6 { get; set; }
    //public string Question7 { get; set; }
    //public string Question8 { get; set; }
    //public string Question9 { get; set; }
    //public string Question10 { get; set; }
    //public string Question11 { get; set; }
    //public string Question12 { get; set; }
    //public string Question13 { get; set; }
    //public string Question14 { get; set; }
    //public string Question15 { get; set; }

}
}

最后在业务逻辑上的按钮点击：

protected void Button1_Click(object sender, EventArgs e)
    {
        try
        {
            FillObjects();

            //if (InsertData.InsertCandidateCompany(_CandidateCompanyInformation )) 
            if (InsertData.AddParticipantlistemployeecode(_DimensionQuestion))
            {
                ShowMessage("Information is saved");
                //Reset();

            }
            else
            {
                ShowMessage("Please try again");

            }
        }
        finally
        {
            _DimensionQuestion = null;

        }
    }

 private void FillObjects()
    {
        List<string> sp = new List<string>();
        _DimensionQuestion = new Cengrow.Survey.Core.Model.DimensionQuestion();
       // _DimensionQuestion.CompanyName = txtCompanyName.Text.Trim();


        sp.Add(txtName1.Text.Trim());
        sp.Add(txtName2.Text.Trim());

您正在向所有三个参数添加相同的值：

new SqlParameter("@CandidateName",s  ),
new SqlParameter("@EmployeeCode",s  ),
new SqlParameter("@EmailId",s

在所有情况下，您都添加了“s”，即 CandidateName。

编辑：候选人应该是一个类：

public class Candidate
{
    public string Name { get; set; }
    public string EmployeeCode { get; set; }
    public string Email { get; set; }

    public Candidate(string name, string code, string email)
    {
        this.Name = name;
        this.EmployeeCode = code;
        this.Email = email;
    }
}

那么您的 DimensionQuestion 应该包含一个

List<Candidate> Candidates

代替

public List<string> CandidateName { get; set; }
public List<string> EmployeeCode { get; set; }
public List<string> EmailId { get; set; }

然后你 FillObjects 方法将候选对象添加到候选列表

Candidates.Add(new Candidate(txtName1.Text.Trim(), 
                                txtEmployeeCode1.Text.Trim(), 
                                TextBox1.Text.Trim()));


Candidates.Add(new Candidate(txtName2.Text.Trim(), 
                                txtEmployeeCode2.Text.Trim(), 
                                TextBox2.Text.Trim()));

最后你的数据层应该是：

foreach (Candidate candidate in dimension.Candidates)
           {
               if (!String.IsNullOrEmpty(candidate.Name))
               {
                   var parameter = new[]
                                {
                                   // new   SqlParameter("@CompanyName",dimension.CompanyName  ),
                                    new SqlParameter("@CandidateName",candidate.Name  ),
                                    new SqlParameter("@EmployeeCode",candidate.Code  ),
                                    new SqlParameter("@EmailId",candidate.Email  ),                                                                             
                                    success,
                                };
                   helper.ExecuteScalar(_cmdtext, CommandType.StoredProcedure, parameter);
               }
           }
