c# 生成二維碼

引用ZXing類庫

實現功能:

1生成帶有Logo二維碼

2 將二維碼繪製到圖片上

3 圖片上繪製文字

 1  public string CreateQrCode(string md5Str,string name,int sex)
 2         {
 3             string str = sex == 1? "先生":"女士";
 4             string logoPath = AppDomain.CurrentDomain.BaseDirectory + "/logo.png";
 5             string qrCodePath = path + DateTime.Now.ToString("yyyyMMddHHmmss") + ".jpg";
 6             string yqPath = AppDomain.CurrentDomain.BaseDirectory + "/yq2.jpg";
 7             string yqCardPath = path + TCommon.Md5(DateTime.Now.ToString("yyyyMMddHHmmss")) + ".jpg";
 8             if (Directory.Exists(path) == false)//如果不存在就創建file文件夾
 9             {
10                 Directory.CreateDirectory(path);
11             }
12             Generate3(md5Str,logoPath,qrCodePath);
13             Image qrCodeImg = new Bitmap(qrCodePath);
14             Image image = new Bitmap(yqPath);
15             Graphics ig = Graphics.FromImage(image);
16             Font font = new Font("Arial", 38,FontStyle.Bold); 
17             Font font2 = new Font("STXINWEI", 38, FontStyle.Bold);
18             Brush brush = System.Drawing.Brushes.Black;
19             SizeF size = ig.MeasureString(name, font2);
20             SizeF size2 = ig.MeasureString(str, font);
21             ig.DrawString(name, font, brush, (720-size.Width-size2.Width) /2, 680);
22             ig.DrawString(str, font, brush, (720 - size.Width - size2.Width) / 2 + size.Width, 680);
23             ig.FillRectangle(Brushes.White, 280, 351, 160, 160);
24             ig.DrawImage(qrCodeImg, 285, 356);
25             image.Save(yqCardPath);
26             return yqCardPath.Substring(2);
27         }
