传递try语句，但数据库不会在C#中更新

using System;
using System.Data.SqlClient;

class Program
{
    static void Main()
    {
        string connectionString = "Data Source=your_server;Initial Catalog=your_database;User ID=your_username;Password=your_password";
        
        try
        {
            using (SqlConnection connection = new SqlConnection(connectionString))
            {
                connection.Open();
                
                // 执行数据库更新操作，例如插入一条新记录
                string sql = "INSERT INTO YourTable (Column1, Column2) VALUES ('Value1', 'Value2')";
                SqlCommand command = new SqlCommand(sql, connection);
                command.ExecuteNonQuery();
                
                Console.WriteLine("数据库更新成功！");
            }
        }
        catch (Exception ex)
        {
            Console.WriteLine("发生异常：" + ex.Message);
        }
    }
}
