My DBRoutines Class:

using System.Threading.Tasks;
using MySql.Data.MySqlClient;
using System.Data;

namespace localhost_54355

    static class DBRoutines
    {
        public static class Insert
        {
            public static void Addcompany(string Employee_UserName, string Employee_Email, string Employee_Password, string Employee_Job, string Employee_FirstName, string Employee_LastName, string Employee_Location, int Employee_Phone, string Employee_CV, string Employee_Availability )
            {
                MySqlConnection con = new MySqlConnection("Database=jobfind;Data Source=localhost;User Id=root;Password=1234");

                MySqlCommand com = new MySqlCommand("Addcompany", con);
                com.CommandType = CommandType.StoredProcedure;

                com.Parameters.AddWithValue("aUserName", Employee_UserName);
                com.Parameters.AddWithValue("aEmployee_Email", Employee_Email);
                com.Parameters.AddWithValue("aEmployee_Password", Employee_Password);
                com.Parameters.AddWithValue("aEmployee_Job", Employee_Job);
                com.Parameters.AddWithValue("aEmployee_FirstName", Employee_FirstName);
                com.Parameters.AddWithValue("aEmployee_LastName", Employee_LastName);
                com.Parameters.AddWithValue("aEmployee_Location", Employee_Location);
                com.Parameters.AddWithValue("aEmployee_Phone", Employee_Phone);
                com.Parameters.AddWithValue("aEmployee_CV", Employee_CV);
                com.Parameters.AddWithValue("aEmployee_Availability", Employee_Availability);


                try
                {
                    con.Open();

                    com.ExecuteNonQuery();
                }
                catch (Exception Ex)
                {

                }
                finally
                {
                    con.Close();
                }
            }

}

}

嘿，我在使用 MySQL 数据库实现注册页面时遇到问题。当我在页面代码中插入“namespace localhost_54355”时，我的按钮、文本框、面板无法识别。但是当我删除“命名空间”时，按钮变得可用，但我的类 DBRoutines 无法识别。你能帮我找出问题所在吗？

谢谢!

注意: 这里的变量 ' DBRoutines.Insert.Addcompany(TextUserName.Text, txtCo_JobPosition.Text, txtCo_JobPositionDescription.Text, txtCo_Email.Text, int.Parse(txtCo_Phone.Text), txtCo_Address.Text); ' 不正确。唯一正确的是“TextUserName.Text”，但它仍然只有在我删除“命名空间”时才能被识别。
