我是初学者，C#中用SoftwareFX.ChartFX.Lite.Chart生成的柱状图，我另加了一个打印button，程序要求点击“打印”按钮时，能实现打印柱状图的功能，如何编写代码？

我是初学者，我不太懂哎，我是把数据导入到chart1生成的柱状图下面是我的程序
 private void button15_Click(object sender, EventArgs e)
        {
            //PrintDocument pd = new PrintDocument();
            printDocument2.PrintPage += new PrintPageEventHandler
                (this.PrintImageHandler);
            this.printDialog1.AllowSomePages = true;
            this.printDialog1.ShowHelp = true;
            printDialog1.Document = printDocument2;

            DialogResult Rest = printDialog1.ShowDialog();
            if (Rest == DialogResult.OK)
            {
                printDocument2.Print();
            }
        }
       private void PrintImageHandler(object sender,PrintPageEventArgs ppeArgs)
        {

            Image curImage = chart1.GetChartBitmap();
            Graphics g = ppeArgs.Graphics;
            
                       if (curImage != null)
            {
                // Draw Image using the DrawImage method
                g.DrawImage(curImage, 100, 100,
                    curImage.Width, curImage.Height);
            }
    }
调试时出现错误说错误    “SoftwareFX.ChartFX.Lite.Chart”并不包含“GetChartBitmap”的定义   那你看我哪儿出错了？该怎么解决？

chart里的柱状图是导入excel数据直接生成的，那DrawToBitmap()的参数的重载如何写啊？

我是那样编的，可是出现错误：无法将类型“void”隐式转换为“System.Drawing.Image”
