Create a Bitmap variable

Private Bitmap chartImage;

Save the chart to memory stream and then create a bitmap with the memory stream.

using (MemoryStream ms = new MemoryStream())
{
    pieChart.SaveImage(ms, ChartImageFormat.Jpeg);
    this.chartImage= new Bitmap(ms);
}

The base Chart class has the DrawToBitmap() method.

In case your chart is too big, catch the exception and use a temporary file with System.IO.Path.GetTempFileName();.
