带有弹出的保存页面，可以设置图片的名字，选择图片保存的格式

private void ExportPicture(string fileName)        {            string saveFileName = "";            SaveFileDialog saveDialog = new SaveFileDialog();            saveDialog.FileName = fileName;            //saveDialog.ShowDialog();            saveFileName = saveDialog.FileName;            saveDialog.Filter = "Bitmap (*.bmp)|*.bmp|JPEG (*.jpg)|*.jpg|EMF (*.emf)|*.emf|PNG (*.png)|*.png|SVG (*.svg)|*.svg|GIF (*.gif)|*.gif|TIFF (*.tif)|*.tif";            saveDialog.FilterIndex = 2;            saveDialog.RestoreDirectory = true;            // Set image file format            if (saveDialog.ShowDialog() == DialogResult.OK)            {                ChartImageFormat format = ChartImageFormat.Bmp;                if (saveDialog.FileName.EndsWith("bmp"))                {                    format = ChartImageFormat.Bmp;                }                else if (saveDialog.FileName.EndsWith("jpg"))                {                    format = ChartImageFormat.Jpeg;                }                else if (saveDialog.FileName.EndsWith("emf"))                {                    format = ChartImageFormat.Emf;                }                else if (saveDialog.FileName.EndsWith("gif"))                {                    format = ChartImageFormat.Gif;                }                else if (saveDialog.FileName.EndsWith("png"))                {                    format = ChartImageFormat.Png;                }                else if (saveDialog.FileName.EndsWith("tif"))                {                    format = ChartImageFormat.Tiff;                }                // Save image                chart1.SaveImage(saveDialog.FileName, format);            }        }
