C#自动生成的方法。如何添加其他参数

正在为本地企业开发收据打印机应用程序。从技术上讲，这是一个重写，我把它看作是一个完整的重构

原始代码如下所示：

private void btn_print_Click(object sender, EventArgs e)
        {

        PrintDialog pd = new PrintDialog();
        PrintDocument doc = new PrintDocument();
        pd.Document = doc;
        doc.PrintPage += new PrintPageEventHandler(pd_printpage);
        DialogResult res = pd.ShowDialog();
        if (res == DialogResult.OK)
        {
            doc.DefaultPageSettings.Landscape = false;
            doc.PrinterSettings.DefaultPageSettings.PaperSize = new PaperSize("Env10", 4, 8);
            doc.Print();
        }

    }
    private void pd_printpage(object sender, PrintPageEventArgs e)
    {
        Graphics gfx = e.Graphics;
        SolidBrush blk = new SolidBrush(Color.Black);
        Font courier = new Font("Courier New", 12);
        Font lucidia = new Font("Lucida Sans", 12);
        Font lucidaplus = new Font("Lucida Sans", 18);
        StringFormat fmt = new StringFormat(StringFormatFlags.DirectionVertical);

        /*****  Create Object for Reciept  *****/
        Recpt rcpt = new Recpt();
        rcpt.Contrib = new ContInfo();
        rcpt.Pri = new Address();
        rcpt.Alt = new Address();

//--- Remainder of function omitted.

这是一个更好的版本，我目前正在工作

static class Printality
    {
        private static SolidBrush Blk = new SolidBrush(Color.Black);
        private static Font CourierBody = new Font("Courier New", 12);
        private static Font LucidaBody = new Font("Lucida Sans", 12);
        private static Font LucidaHeader = new Font("Lucida Sans", 18);
        private static StringFormat fmt;

        public static void PrintReciept(Receipt _rec)
        {
            PrintDialog pd = new PrintDialog();
            PrintDocument doc = new PrintDocument();
            doc.PrintPage += new PrintPageEventHandler(pd_printPage);
        }

        private static void pd_printPage(object sender, PrintPageEventArgs e)
        {
            Graphics gfx = e.Graphics;
            fmt = new StringFormat(StringFormatFlags.DirectionVertical);

        }
    }

最大的问题是：我正在将Receipt对象传递给函数

printReceipt（）

我应该如何将它传递给

pd\u printPage（）

？

如果我清楚地理解了您的问题，您希望将参数传递给事件

doc.PrintPage += (sender, e) => pd_printPage(sender, e, _rec);

private static void pd_printPage(object sender, PrintPageEventArgs e, Receipt rec)
{
    Graphics gfx = e.Graphics;
    fmt = new StringFormat(StringFormatFlags.DirectionVertical);

}

试试：静态类Printality:printcumentah！你完全明白了！我在JavaScript领域待得太久了。我没有意识到C#有那种功能！非常感谢。
