C#-Winform-打印控件

控件设计：

设置上述出去Button和Form控件的剩余控件（PrintDialog1等）的Document属性为相应的PrintDocument。

代码：

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;

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

            this.printDocument1.OriginAtMargins = true;//启用页边距
            this.pageSetupDialog1.EnableMetric = true; //以毫米为单位
        }

        /// <summary>
        /// 打印
        /// </summary>
        private void button1_Click(object sender, EventArgs e)
        {
            if (this.printDialog1.ShowDialog() == DialogResult.OK)
            {
                this.printDocument1.Print();
            }
        }

        /// <summary>
        /// 打印设置
        /// </summary>
        private void button2_Click(object sender, EventArgs e)
        {
            this.pageSetupDialog1.ShowDialog(); 
        }

        /// <summary>
        /// 打印预览
        /// </summary>
        private void button3_Click(object sender, EventArgs e)
        {
            this.printPreviewDialog1.ShowDialog(); 
        }

        private void printDocument1_PrintPage(object sender, System.Drawing.Printing.PrintPageEventArgs e)
        {
            ////----------------打印内容 为 整个Form----------------
            //Image myFormImage;
            //myFormImage = new Bitmap(this.Width, this.Height);
            //Graphics g = Graphics.FromImage(myFormImage);
            //g.CopyFromScreen(this.Location.X, this.Location.Y, 0, 0, this.Size);
            //e.Graphics.DrawImage(myFormImage, 0, 0);

            ////----------------打印内容 为 局部的 this.groupBox1----
            //Bitmap _NewBitmap = new Bitmap(groupBox1.Width, groupBox1.Height);
            //groupBox1.DrawToBitmap(_NewBitmap, new Rectangle(0, 0, _NewBitmap.Width, _NewBitmap.Height));
            //e.Graphics.DrawImage(_NewBitmap, 0, 0, _NewBitmap.Width, _NewBitmap.Height); 

            //------------------打印内容 为 自定义文本内容------------
            Font font = new Font("宋体", 12);
            Brush bru = Brushes.Blue;
            //for (int i = 1; i <= 5; i++)
            //{
                
            //}
            e.Graphics.DrawString("Hello world ", font, bru, 10, 10);
        }
    }
}

完成。
