用 saveFileDialog 控件            this._saveFileDialog.FileName = "imageT1";
            this._saveFileDialog.Filter = "PNG Format (*.png)|*.png|Gif Format (*.gif)|*.gif|Jpeg Format (*.jpg)|*.jpg|Tiff Format (*.tif)|*.tif|Bmp Format (*.bmp)|*.bmp";
            if (this._saveFileDialog.ShowDialog() == DialogResult.OK)
            {
    Stream stream = this._saveFileDialog.OpenFile();
                if (stream != null)
                {                    ImageFormat png = ImageFormat.Png;
                    if (this._saveFileDialog.FilterIndex == 3)
                    {
                        png = ImageFormat.Gif;
                    }
                    else if (this._saveFileDialog.FilterIndex == 4)
                    {
                        png = ImageFormat.Jpeg;
                    }
                    else if (this._saveFileDialog.FilterIndex == 5)
                    {
                        png = ImageFormat.Tiff;
                    }
                    else if (this._saveFileDialog.FilterIndex == 6)
                    {
                        png = ImageFormat.Bmp;
                    }                    //           Bitmap bitmap = new Bitmap(this.pictureBox1.Image);                    //            gall.DrawImage(this.pictureBox1.Image,0,0);                    //       this.panel1
                    imageT1.Save(stream, png);                    stream.Close();
                }            }

基本思路是这样，其它的自己扩展Bitmap imageT1 = new Bitmap(86, 25);SaveFileDialog sPath = new SaveFileDialog();
sPath.InitialDirectory = Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments);
sPath.Filter = "PNG(*.png)|*.png";
sPath.FileName = "imageT1";
if (sPath.ShowDialog() == DialogResult.OK)
{
    imageT1.Save(sPath.FileName); 
}
