1、中間含圖片的二維碼生成實例這是一個簡單的二維碼生成實例，我們就用c#的windows程序來寫吧。1.新建一個windows程序，然后引用ThoughtWorks.QRCode.dll。這個dll沒有可以到網上去copy一個下來。首先畫好這樣一個界面，界面非常簡單，但是太丑一點，我們做好了再放一個皮膚上去。 接下來我們開始寫后臺代碼吧！using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.T

2、ext; using System.Windows.Forms; using ThoughtWorks.QRCode.Codec; using System.IO; using System.Drawing.Imaging; namespace WindowsFormsApplication1 Public partial class Form1:Form public Form1() InitializeComponent(); Private object logoImg; /用于存放logo圖片Private void Form1_Load(object sender, EventArg

3、s e) this.skinEngine1.SkinFile = Calmness.ssk; / /獲取二維碼生成圖片/ / publicBitmap getcode(string writeStr) QRCodeEncoder qRCodeEncoder = new QRCodeEncoder (); qRCodeEncoder.QRCodeEncodeMode = QRCodeEncoder. ENCODE_MODE.BYTE;/設置二維碼編碼格式 qRCodeEncoder.QRCodeScale = 4; /設置編碼測量度 qRCodeEncoder.QRCodeVersion = 7

4、; /設置編碼版本 qRCodeEncoder.QRCodeErrorCorrect = QRCodeEncoder. ERROR_CORRECTION.M; /設置錯誤校驗Bitmap image = qRCodeEncoder.Encode(writeStr); return image; / /獲取logo / / Public Bitmap getlogo() Bitmap newBmp = new Bitmap (logo.jpg);/獲取圖片對象Bitmap bmp = new Bitmap (newBmp, 30, 30); /縮放return bmp; / /二維碼保存/ /

5、/ Private void Save_Btn_Click(object sender, EventArgs e) SaveFileDialog saveFile = new SaveFileDialog ();/創建保存對話框 saveFile.Filter = JPEG|*.jpeg;*.jpg|位圖文件|*.bmp|所有文件|*.*;/設置保存的圖片格式if (pictureBox1.Image != null) if (saveFile.ShowDialog() = DialogResult.OK) string sFilePathName = saveFile.FileName; I

6、mage img = pictureBox1.Image; img.Save(sFilePathName); else MessageBox.Show(請先生成二維碼！); / / 二維碼生成/ / / Private void ShengCheng_Btn_Click(object sender, EventArgs e) if (Str_Tbx.Text.Trim() != ) /驗證輸入的生成內容是否為空 Bitmap bCode = getcode(Str_Tbx.Text); /獲取二維碼圖片 if (logoImg = null) pictureBox1.Image = bCode

7、; else Bitmap bLogo = logoImg as Bitmap; /獲取logo圖片對象bLogo = new Bitmap(bLogo, 30, 30); /改變圖片的大小這里我們設置為30 int Y = bCode.Height; int X = bCode.Width; Point point = new Point(X / 2 - 15, Y / 2 - 15);/logo圖片繪制到二維碼上，這里將簡單計算一下logo所在的坐標 Graphics g = Graphics.FromImage(bCode);/創建一個畫布 g.DrawImage(bLogo, poin

8、t);/將logo圖片繪制到二維碼圖片上 pictureBox1.Image = bCode; else MessageBox.Show(輸入生成內容！); / / logo上傳 / / / Private void UpLogo_Btn_Click(object sender, EventArgs e) OpenFileDialog openFileDialog = new OpenFileDialog();/文件打開對話框 openFileDialog.Filter = JPEG|*.jpeg;*.jpg|位圖文件|*.bmp|所有文件|*.*;/只能打開我們設置的這幾類文件 if (openFileDialog.ShowDialog() = DialogResult.OK) string fileName = openFileDialog.FileName; Bitmap
