今天我的任務是進行程式碼的編寫，

今天編寫的程式碼是編寫生成二維碼

程式碼如下：

//生成二維碼-生成
        private void button3_Click(object sender, EventArgs e)
        {
            //設定QR二維碼的規格
            ZXing.QrCode.QrCodeEncodingOptions qrEncodeOption = new ZXing.QrCode.QrCodeEncodingOptions();
            //設定編碼格式，否則中文亂碼
            qrEncodeOption.CharacterSet = "UTF-8";
            //設定寬和高
            qrEncodeOption.Height = 200;
            qrEncodeOption.Width = 200;
            //設定周圍空白邊距
            qrEncodeOption.Margin = 1;
            ZXing.BarcodeWriter wr = new BarcodeWriter();
            //二維碼
            wr.Format = BarcodeFormat.QR_CODE;
            wr.Options = qrEncodeOption;
            //生成二維碼
            Bitmap image = wr.Write(textBox4.Text);
            //顯示
            pictureBox3.Image = image;
        }         //生成二維碼-儲存
        private void button7_Click(object sender, EventArgs e)
        {
            //儲存圖片
            saveImage(pictureBox3, textBox4.Text);
        }         //讀取二維碼-選擇圖片
        private void button5_Click(object sender, EventArgs e)
        {
            //開啟圖片
            openImage(textBox6, pictureBox4);
        }
