C# 实现简单打印（三）认识打印控件,创建一个带打印功能的程序

一.分析步骤:

首先,在工具箱中添加一个PrintDocument的主要打印控件

然后,先后添加PrintDialog,PagePreviewDialog,PageSetDialog控件,并同时,设置它们的Document的属性为开始添加的PrintDocument的Name

最后,分别完善实现打印,预览的事件代码

二.效果截图

三.程序代码

public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
            btnPreview.Click += btnPreview_Click;
            btnPrint.Click += btnPrint_Click;
        }
        /// <summary>
        /// 打印
        /// </summary>
        /// <param name="sender"></param>
        /// <param name="e"></param>
        void btnPrint_Click(object sender, EventArgs e)
        {
            //打印机设置
            if (printDialog.ShowDialog()==DialogResult.OK)
            {
                //页面设置
                if (pageSetupDialog.ShowDialog() == DialogResult.OK)
                {
                    printDocument.Print();
                }
            }
        }
        /// <summary>
        /// 打印预览
        /// </summary>
        /// <param name="sender"></param>
        /// <param name="e"></param>
        void btnPreview_Click(object sender, EventArgs e)
        {
            printPreviewDialog.ShowDialog();
        }
        /// <summary>
        /// 打印内容
        /// </summary>
        /// <param name="sender"></param>
        /// <param name="e"></param>
        private void printDocument_PrintPage(object sender, PrintPageEventArgs e)
        {
            e.Graphics.DrawString("小样你好", new Font("宋体", 12), Brushes.Black, 10, 10);
        }

    }
