printPreview横向模式

Question

如何将打印预览和打印代码设置为横向?

 this.printPreviewDialog1.AutoScrollMargin = new System.Drawing.Size(0, 0);
            this.printPreviewDialog1.AutoScrollMinSize = new System.Drawing.Size(0, 0);
            this.printPreviewDialog1.ClientSize = new System.Drawing.Size(700, 600);
            this.printPreviewDialog1.Document = this.printDocument1;
            this.printPreviewDialog1.Enabled = true;
            this.printPreviewDialog1.Icon = ((System.Drawing.Icon)(resources.GetObject("printPreviewDialog1.Icon")));
            this.printPreviewDialog1.Name = "printPreviewDialog1";
            this.printPreviewDialog1.Visible = false;
            // 
            // printDocument1
            // 
            this.printDocument1.PrintPage += new System.Drawing.Printing.PrintPageEventHandler(this.printDocument1_PrintPage_1);

Answer 1

成功了

this.printDocument1.DefaultPageSettings.Landscape = true;

Answer 2

var doc = new PrintDocument();
doc.DefaultPageSettings.Landscape = true;

有效果吗?

它可能也会处理打印预览问题。

Answer 3

这对我有用

private void button_Click(object sender, EventArgs e)
{
    printPreviewDialog1.Document = printDocument1;
    printDocument1.DefaultPageSettings.Landscape = true;
    printPreviewDialog1.ShowDialog();
}
