写入pdf并在Windows窗体应用程序中打印[关闭]

Question

我正在使用 c# 在 Windows 窗体应用程序中开发一个账单管理系统。 在订单表格中，我必须以 pdf 格式生成发票，保存 pdf 并触发打印。 有两个按钮 GenerateBill 和 GenerateBill&Print。当我单击 GenerateBill&Print 时，订单详细信息应保存在数据库中并打印 pdf。我需要在 windows 窗体中创建 pdf 的代码。

namespace Full_Profile1
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void Form1_Load(object sender, EventArgs e)
        {

            //This is the absolute path to the PDF that we will create
            string outputFile = Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.Desktop), "Sample.pdf");

            //Create a standard .Net FileStream for the file, setting various flags
            using (FileStream fs = new FileStream(outputFile, FileMode.Create, FileAccess.Write, FileShare.None))
            {
                //Create a new PDF document setting the size to A4
                using (Document doc = new Document(PageSize.A4))
                {
                    //Bind the PDF document to the FileStream using an iTextSharp PdfWriter
                    using (PdfWriter w = PdfWriter.GetInstance(doc, fs))
                    {
                        //Open the document for writing
                        doc.Open();

                        //Create a table with two columns
                        PdfPTable t = new PdfPTable(2);

                        //Borders are drawn by the individual cells, not the table itself.
                        //Tell the default cell that we do not want a border drawn
                        t.DefaultCell.Border = 0;

                        //Add four cells. Cells are added starting at the top left of the table working left to right first, then down
                        t.AddCell("R1C1");
                        t.AddCell("R1C2");
                        t.AddCell("R2C1");
                        t.AddCell("R2C2");

                        //Add the table to our document
                        doc.Add(t);

                        //Close our document
                        doc.Close();
                    }
                }
            }

            this.Close();
        }
    }
}
