今天我的任务是继续编写代码
今天我编写的代码是读取二维码
代码如下：
//读取二维码-读取 private void button9_Click(object sender, EventArgs e) { DecodingOptions decodeOption = new DecodingOptions(); decodeOption.PossibleFormats = new List<BarcodeFormat>() { BarcodeFormat.QR_CODE }; //读取二维码 ZXing.BarcodeReader br = new BarcodeReader(); br.Options = decodeOption; ZXing.Result rs = br.Decode(pictureBox4.Image as Bitmap); if (rs == null) { MessageBox.Show("读取失败"); } else { //读取成功 textBox7.Text = rs.Text; } }
//保存图片 private void saveImage(PictureBox imagePb, string filename) { try { SaveFileDialog fileDialog = new SaveFileDialog(); fileDialog.InitialDirectory = Environment.GetFolderPath(Environment.SpecialFolder.DesktopDirectory); //默认保存目录 fileDialog.RestoreDirectory = true; //对话框记忆之前打开的目录 fileDialog.Filter = "图片文件(*.jpg)|*.jpg"; //显示的文件类型 fileDialog.FileName = filename + ".jpg"; //默认文件名 if (fileDialog.ShowDialog() == System.Windows.Forms.DialogResult.OK) { string filePath = fileDialog.FileName; imagePb.Image.Save(filePath); //保存 } } catch (Exception ex) { MessageBox.Show(filename + " 保存失败： " + ex.Message); } }
//打开图片 private void openImage(TextBox textBox, PictureBox imagePb) { OpenFileDialog ofd = new OpenFileDialog(); ofd.InitialDirectory = Environment.GetFolderPath(Environment.SpecialFolder.DesktopDirectory); //默认打开目录 ofd.Filter = "图片文件|*.jpg|所有文件|*.*"; //显示的文件类型 ofd.RestoreDirectory = true; //对话框记忆之前打开的目录 ofd.FilterIndex = 1; //文件类型的显示顺序 if (ofd.ShowDialog() == DialogResult.OK) //选中文件 { textBox.Text = ofd.FileName; //选中的音乐文件的路径 imagePb.Image = new Bitmap(ofd.FileName); } }
private void textBox4_TextChanged(object sender, EventArgs e) {
}
} }
