c# winform 程序 怎么打印 Panel 或者Picturebox 里的内容。

Answer 1

printDocument1.PrintPage += new System.Drawing.Printing.PrintPageEventHandler(this.pd_PrintPage);
printDocument1.Print();
}
private void pd_PrintPage(object sender, System.Drawing.Printing.PrintPageEventArgs e)
{
e.Graphics.DrawImage(pictureBox1.Image, 0, 0, pictureBox1.Image.Width, pictureBox1.Image.Height);

Answer 2

不难吧，先获取Panel的矩形，然后用drawImage画出图片，进行打印

Answer 3

由第三方的插件，可以去网上找找看，自己写的话太麻烦...
