过载方法?为什么这个函数不起作用

{
    class Program
    {
        static void Main(string[] args)
        {
            int id = 0, stock = 0, published = 0, newstock;
            double price = 0.00;
            string type = " ", title = " ", author = " ";
            Program inventroy = new Program();
            inventroy.read_one_record(ref id, ref stock, ref published, ref price, ref type, ref title, ref author);
            Console.WriteLine("Update Number In Stock");
            Console.WriteLine("=======================");
            Console.Write("Item ID: ");
            Console.WriteLine(id);
            Console.Write("Item Type: ");
            Console.WriteLine(type);
            Console.Write("Price: ");
            Console.WriteLine(price);
            Console.Write("Number In Stock: ");
            Console.WriteLine(stock);
            Console.Write("Title: ");
            Console.WriteLine(title);
            Console.Write("Author/Artist: ");
            Console.WriteLine(author);
            Console.Write("Published: ");
            Console.WriteLine(published);
            Console.WriteLine("=======================");
            Console.Write("Please Enter New Stock Number: ");
            string line = Console.ReadLine();
            newstock = int.Parse(line);
            Program writeinv = new Program();
            writeinv.write_one_record(ref id, ref newstock, ref published, ref price, ref type, ref title, ref author);
        }
        void read_one_record(ref int id, ref int stock, ref int published, ref double price, ref string type, ref string title, ref string author)
        {
            StreamReader myFile = File.OpenText("Inventory.dat");
            id = int.Parse(myFile.ReadLine());
            stock = int.Parse(myFile.ReadLine());
            published = int.Parse(myFile.ReadLine());
            price = double.Parse(myFile.ReadLine());
            type = myFile.ReadLine();
            title = myFile.ReadLine();
            author = myFile.ReadLine();
            myFile.Close();
        }
        void write_one_record(int id, int newstock, int published, double price, string type, string title, string author)
        {
            StreamWriter myFile = new StreamWriter(File.OpenWrite("Inventory.dat"));

            myFile.WriteLine(id);
            myFile.WriteLine(newstock);
            myFile.WriteLine(published);
            myFile.WriteLine(price);
            myFile.WriteLine(type);
            myFile.WriteLine(title);
            myFile.WriteLine(author);
            myFile.Close();
        }
    }
}

有人可以编译这个(或者只是将代码粘贴到编译器中(并告诉我为什么writeinv.write_one_record(ref id，ref newstock，ref publish，ref price，ref type，ref title，ref author(;说它有无效的参数？

"'as2.programs.write_one_record(int， int， int， double， string， string， string(' 的最佳重载方法匹配有一些无效的参数。
