在ASP net中如何将SQL查询的数据存储到变量中？

using System;
using System.Data.SqlClient;

namespace YourNamespace
{
    public class YourClass
    {
        public void YourMethod()
        {
            string connectionString = "YourConnectionString"; // 替换为实际的连接字符串

            using (SqlConnection connection = new SqlConnection(connectionString))
            {
                string query = "SELECT Column1, Column2 FROM YourTable"; // 替换为实际的查询语句

                SqlCommand command = new SqlCommand(query, connection);

                connection.Open();

                SqlDataReader reader = command.ExecuteReader();

                while (reader.Read())
                {
                    int column1Value = reader.GetInt32(0); // 获取第一列的整数值
                    string column2Value = reader.GetString(1); // 获取第二列的字符串值

                    // 将获取的值存储到变量中，进行后续处理
                    // TODO: 进行你的逻辑操作
                }

                reader.Close();
                connection.Close();
            }
        }
    }
}
