如何使用asp.net查看SQL Server中的数据是否以整数开头？

using System;
using System.Data.SqlClient;
using System.Text.RegularExpressions;

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

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

            while (reader.Read())
            {
                string data = reader["Your_Column"].ToString();

                // 使用正则表达式检查数据是否以整数开头
                bool isInteger = Regex.IsMatch(data, @"^\d+");

                if (isInteger)
                {
                    Console.WriteLine("Data starts with an integer: " + data);
                }
                else
                {
                    Console.WriteLine("Data does not start with an integer: " + data);
                }
            }

            reader.Close();
        }
    }
}
