问题是该文件未保存为JPEG.只是一个普通的文件.

到目前为止这是我的代码:

private void btnSave_Click(object sender, EventArgs e)
{
    saveDialog.FileName = txtModelName.Text;

    if (saveDialog.ShowDialog() == DialogResult.OK)
    {
        Bitmap bmp = new Bitmap(pnlDraw.Width, pnlDraw.Height);

        pnlDraw.DrawToBitmap(bmp, new Rectangle(0, 0,
            pnlDraw.Width, pnlDraw.Height));

        bmp.Save(saveDialog.FileName, System.Drawing.Imaging.ImageFormat.Jpeg);
    }
}
