推荐答案

这对于您的目的来说可能有点复杂，但我已经使用了 PrintDocument 对象在报表页面上绘制背景图像.您可以执行类似的操作，使用 PrintPageEventArgs 中的 Graphics 对象绘制"图表图像.

This might be a bit convoluted for your purposes, but I've used the PrintDocument object to draw a background image on pages of a report. You could do something similar, where you use the Graphics object from the PrintPageEventArgs to "paint" your chart image.

此代码将打印一个 1 页的文档，在上角绘制一个小矩形.我认为你可以用图表的绘图替换那里的绘图

This code would print a 1 page document with a small rectangle drawn in the upper corner. I would think you could replace the drawing there with the drawing of your chart

class Program
{
public class Document : System.Drawing.Printing.PrintDocument
{
    protected override void OnBeginPrint(System.Drawing.Printing.PrintEventArgs e)
    {
        base.OnBeginPrint(e);
    }
    protected override void OnPrintPage(System.Drawing.Printing.PrintPageEventArgs e)
    {
        e.Graphics.DrawRectangle(SystemPens.ActiveBorder, new Rectangle(0, 0, 20, 20));
    }
}

static void Main(string[] args)
{
    System.Drawing.Printing.PrintDocument pd = new Document();
    pd.Print();
}

}
