如何在SQL server中使用SqlReader将对象类型转换为整型

using System;
using System.Data.SqlClient;

class Program
{
    static void Main()
    {
        string connectionString = "Your_Connection_String";
        string query = "SELECT Your_Column FROM Your_Table";

        using (SqlConnection connection = new SqlConnection(connectionString))
        {
            SqlCommand command = new SqlCommand(query, connection);
            connection.Open();

            using (SqlDataReader reader = command.ExecuteReader())
            {
                while (reader.Read())
                {
                    int intValue = reader.GetInt32(0); // 将第一列的对象类型转换为整型
                    Console.WriteLine(intValue);
                }
            }
        }
    }
}
