c#打印图片文件问题
当前程序文件夹pic下有4张jpg图片文件,单击winform窗体上的"打印"按钮后想把这4张图片通过A4的纸打印出来,每一张图片打印一页,请教代码如何实现

[解决办法]

C# code

拉一个printDocument控件到界面。 打印按钮的代码： C# codeCode highlighting produced by Actipro CodeHighlighter (freeware)http://www.CodeHighlighter.com/        private void button2_Click(object sender, EventArgs e)//执行打印        {            PrintDialog MyPrintDg = new PrintDialog();            MyPrintDg.Document = printDocument1;            if (MyPrintDg.ShowDialog() == DialogResult.OK)            {                try                {                    printDocument1.Print();                }                catch                {   //停止打印                    printDocument1.PrintController.OnEndPrint(printDocument1, new System.Drawing.Printing.PrintEventArgs());                }            }        }另外还要设置PrintPage事件：C# codeCode highlighting produced by Actipro CodeHighlighter (freeware)http://www.CodeHighlighter.com/        private void printDocument1_PrintPage(object sender, System.Drawing.Printing.PrintPageEventArgs e)        {            e.Graphics.DrawImage(pictureBox1.Image, 20, 20);        }
[解决办法]
先在界面上拖入printDocument控件，然后打印事件中写：

byte[] input = new Byte[100000];

//读取图片
FileStream fs = new FileStream(@"图片路径", FileMode.Open, FileAccess.Read);
fs.Read(input, 0, 100000);

//设置打印页面
printDocument1.DefaultPageSettings.Landscape = true;

//向打印页绘制图片
Image image = Image.FromStream(fs);
e.Graphics.DrawImage(image, 20, 20);

//打印
printDocument1.Print();
