关于c#直接打印问题

[gjwcy510]

我用的是PrintDocument控件，能不能直接打印，不弹出对话框，打印panel里面的内容啊。 panel的id是 "panel1"

[lizhibin11]

不可以，必须在打印时用GDI+画。

楼上的朋友，你好，能不能具体一点啊

这是个示例，可以把对话框部分去掉，不弹出对话框直接打印你下面画的内容。

这是我的一个例子

        public static int index = 0;
        private void printDocument1_PrintPage(object sender, System.Drawing.Printing.PrintPageEventArgs e)
        {
            Graphics gp = e.Graphics;
            int[] cellWidth = { 45, 55, 95, 55, 100, 64, 64, 64, 64, 64, 55 };
            System.Drawing.Font headFont = new System.Drawing.Font("宋体", 20, System.Drawing.FontStyle.Regular);
            SolidBrush brush = new SolidBrush(System.Drawing.Color.Black);//刷子
            StringFormat drawFormat = new StringFormat();//打印的字符串的格式
            drawFormat.Alignment = StringAlignment.Center;
            drawFormat.LineAlignment = StringAlignment.Center;
            int rowPerPage = 33;
            string head = kssj.Text + "至" + jssj.Text + "司机工资表";
            gp.DrawString(head, headFont, brush, 250, 100);

            object[] pchars = { "序号", "个人编码", "姓名", "趟数", "应发工资", "保费", "水费", "扣款", "退款", "实发工资", "备注" };
            Printb.rowprint(100 + headFont.Height, 50, pchars, cellWidth, gp, drawFormat);
            int currentRow = 0;
            while (currentRow < rowPerPage && index < dggz.Items.Count)
            {
                if (index == dggz.Items.Count)
                    break;
                pchars = ((DataView)dggz.ItemsSource).Table.Rows[index].ItemArray;
                Printb.rowprint(150 + headFont.Height + currentRow * 26, 26, pchars, cellWidth, gp, drawFormat);
                currentRow++;
                index++;
            }
            if (index < dggz.Items.Count)
            {
                e.HasMorePages = true;
            }
            else
            {
                e.HasMorePages = false;
                index = 0;
                ((PrintDocument)sender).PrintPage -= printDocument1_PrintPage;
            }
        }

    class Printb
    {
        public static void rowprint(int pointheight, int height, object[] chars, int[] widths, Graphics gp, StringFormat df)
        {
            Font cellFont = new Font("宋体", 12F, FontStyle.Regular, GraphicsUnit.Point, ((byte)(134)));
            rowprint(pointheight, height, chars, widths, gp, df, cellFont);
        }

            for (int i = 0; i < chars.Length; i++)
            {
                if (i > 0)
                    pointwidth = pointwidth + widths[i - 1];
                PrintCell pc = new PrintCell(chars[i].ToString(), widths[i], height, ft);
                Point pt = new Point(pointwidth, pointheight);
