感觉这个问题比较难，怎样将dataGridView的当前行保存为图片

Question

RT。
if ( dataGridView1.SelectedRows != 1 )
{
    returnl;
}Bitmap bmp = new Bitmap(dataGridView1.Width, dataGridView1.CurrentRow.Height);// 怎样将当前行转换为图片 ，保存到bmp中呢？ 谢谢

Answer 1

比如　dataGridView1.DrawToBitmap 可以将dataGridView1保存为图片 ，但是我现在只想将选中的当前行保存为图片 。谢谢

Answer 2

看来高手都忙着养家糊口去了，那我有个法你可以试一下，用那个DrrawToBitmap()存在图片，如bmp1(说实话，这一步我怀疑够呛能行，你先一试吧，不行我再想招儿！！);然后用Bitmap类的Clone方法复制其中的一部分，具体由Rectangle的参数决定,为了取得有效的Rectangle，你应先计算选中行的坐标！

那只有载图了.
以下方法你参照一下       public void GetImage()//载取屏幕特定位置
        {
            try
            {
                PrintPreviewDialog ppvw = new PrintPreviewDialog();
                i = new Bitmap(this.panelChart.Width, this.panelChart.Height);
                Graphics g = Graphics.FromImage(i);
                Point p = panelChart.PointToScreen(panelChart.Location);
                g.CopyFromScreen(p.X / 2+5, p.Y - 12, 0, 0, new Size(this.panelChart.Width, this.panelChart.Height-5));
                ppvw.Document = printDoc;
                printDoc.DefaultPageSettings.Landscape = true;
                printDoc.PrintPage += new System.Drawing.Printing.PrintPageEventHandler(PrintDoc_PrintPage);
                if (ppvw.ShowDialog() != DialogResult.OK)
                {
                    printDoc.PrintPage -= new System.Drawing.Printing.PrintPageEventHandler(PrintDoc_PrintPage);
                    return;
                }
                printDoc.Print();
                g.Dispose();
            }
            catch
            {}
        }

  if (dataGridView1.SelectedRows.Count != 0)
            {
                DataGridViewRow _Row = dataGridView1.SelectedRows[0];
                dataGridView1.FirstDisplayedCell = _Row.Cells[0];
                Rectangle _Rectangle = dataGridView1.GetRowDisplayRectangle(_Row.Index,false);
                Rectangle _AllCount = dataGridView1.GetColumnDisplayRectangle(0, false);
                for (int i = 0; i != dataGridView1.Columns.Count; i++)
                {
                    _AllCount.X += dataGridView1.Columns[i].Width;
                }
                _Rectangle.Width = _AllCount.X;                int _Width = dataGridView1.Width;
                dataGridView1.Width = _Rectangle.X + _Rectangle.Width;
                _Row.Selected = false;
                Bitmap _NewBitmap = new Bitmap(dataGridView1.Width, dataGridView1.Height);              
                dataGridView1.DrawToBitmap(_NewBitmap, new Rectangle(0, 0, _NewBitmap.Width, _NewBitmap.Height));
                _Row.Selected = true;
                dataGridView1.Width = _Width;
                this.BackgroundImage = _NewBitmap.Clone(_Rectangle,_NewBitmap.PixelFormat);
            }
