SqlDataReader 填充结构

Question

有一个私有的“Employee”类对象反映了公共结构“empStruct”。我需要使用 SQLReader 从查询中读取行值以填充结构，然后将对象设置为等于结构值。我认为有一种更简单的方法，但我对此很陌生。

public struct empStruct
    {
        public int eid;
        public string lastname;
        public string firstname;
        public DateTime birthdate;
        public DateTime hiredate;
        public bool ishourly;
        public decimal payrate;
    }
        public static bool SelectEmployee(int eid)
    {
        empStruct SelectRecord = new empStruct();
        Employee newEmp = new Employee();
        string sqlText;

        sqlText = "SELECT EID,EID, LastName, FirstName, BirthDate, HireDate, IsHourly, PayRate ";
        sqlText += "FROM Employee ";
        sqlText += "WHERE EID = @EID ";

        using (SqlConnection connection = new SqlConnection(connectionString))
        {

            SqlCommand command = new SqlCommand(sqlText, connection);
            command.CommandType = CommandType.Text;
            command.Parameters.AddWithValue("@EID", eid);
            connection.Open();

            SqlDataReader reader = command.ExecuteReader();

            //Call Read before accessing data.
            while (reader.Read())
            {
                ???
            }
            newEmp = SelectRecord;

        }

我知道“//Call Read...”之后的所有内容都不完整，我无法弄清楚这个阅读器是如何工作的。

Answer 1

while (reader.Read())
{
newEmp.eid = (int)reader("EID");
newEmp.firstname = (string)reader("FirstName");
....
}

Answer 2

也许像这样加载结构

while (reader.Read())            {
   newEmp.lastname = reader.GetString(1);
   newEmp.firstname  = reader.GetString(2);


}
