如何使用c#sql server向现有表添加新行

using System;
using System.Data.SqlClient;

namespace AddRowToTable
{
    class Program
    {
        static void Main(string[] args)
        {
            string connectionString = "Server=localhost;Database=myDatabase;User Id=myUsername;Password=myPassword;";
            string tableName = "myTable";

            using (SqlConnection connection = new SqlConnection(connectionString))
            {
                connection.Open();

                string insertCommand = $"INSERT INTO {tableName} (column1, column2, column3) VALUES (@value1, @value2, @value3)";

                using (SqlCommand command = new SqlCommand(insertCommand, connection))
                {
                    command.Parameters.AddWithValue("@value1", "value1");
                    command.Parameters.AddWithValue("@value2", "value2");
                    command.Parameters.AddWithValue("@value3", "value3");

                    int rowsAffected = command.ExecuteNonQuery();

                    Console.WriteLine($"{rowsAffected} row(s) added to {tableName}.");
                }
            }
        }
    }
}
