插入查询没有给出任何错误,但数据没有插入到数据库中。当我在sql server中检查数据库时,似乎没有数据插入。我不确定代码的哪一部分有错误。

以下代码:

using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Data;
using System.Data.SqlClient;

namespace PayrollSystem05
{
    public partial class employee : System.Web.UI.Page
    {
      protected void Page_Load(object sender, EventArgs e)
        {

        }


protected void btnAdd_Click1(object sender, EventArgs e)
        {
            SqlConnection con = new SqlConnection("Data Source=DESKTOP-M0G68DT\\SQLEXPRESS;Initial Catalog=PRS;Integrated Security=True");
            SqlCommand cmd = new SqlCommand(@"INSERT INTO [payslip].[employee]
           ([emp_id]
           ,[emp_name]
           ,[emp_ic]
           ,[emp_address]
           ,[emp_mobile]
           ,[emp_email]
           ,[emp_startdate])
     VALUES
           ('"+ txtID.Text +"', '"+ txtName.Text +"', '"+ txtIC.Text +"', '"+ txtAdd.Text + "', '"+ txtMob.Text +"', '"+ txtEmail.Text +"', '" + txtStart.Text + "')", con);
            con.Open();
            cmd.ExecuteNonQuery();
            con.Close();
            Response.Write("<script>alert('Employee added successfully.')</script>");
        }
    }
}```

您可以将下面的代码与您的代码相同,我只进行了一些更改以使其更加清晰易读。

var connectionString = @"Data Source=DESKTOP-M0G68DT\SQLEXPRESS;Initial Catalog=PRS;Integrated Security=True";
var queryString = @"INSERT INTO [payslip].[employee]
           (
              [emp_id]
             ,[emp_name]
             ,[emp_ic]
             ,[emp_address]
             ,[emp_mobile]
             ,[emp_email]
             ,[emp_startdate]
            )
          VALUES
            (
              @emp_id
             ,@emp_name
             ,@emp_ic
             ,@emp_address
             ,@emp_mobile
             ,@emp_email
             ,@emp_startdate
            )";

        using (SqlConnection sqlConnection = new SqlConnection(connectionString))
        {
            using (SqlCommand command = sqlConnection.CreateCommand())
            {
                command.CommandText = queryString;
                command.Parameters.AddWithValue("@emp_id", txtID.Text);
                command.Parameters.AddWithValue("@emp_name", txtName.Text);
                command.Parameters.AddWithValue("@emp_ic", txtIC.Text);
                command.Parameters.AddWithValue("@emp_address", txtAdd.Text);
                command.Parameters.AddWithValue("@emp_mobile", txtMob.Text);
                command.Parameters.AddWithValue("@emp_email", txtEmail.Text);
                command.Parameters.AddWithValue("@emp_startdate", txtStart.Text);

                command.ExecuteNonQuery();
            } 
        }
        Response.Write("<script>alert('Employee added successfully.')</script>");
