//WIFI二维码
//WiFi generator = new WiFi("My-WiFis-Name", "s3cr3t-p4ssw0rd", WiFi.Authentication.WPA);
//string payload = generator.ToString();

//邮件二维码
//Mail generator = new Mail("[email protected]", "Look at this!", "Hi John, have a look at this QRCoder library!");
//string payload = generator.ToString();

//网址
//Url generator = new Url("https://github.com/codebude/QRCoder/");
//string payload = generator.ToString();

//电话
//PhoneNumber generator = new PhoneNumber("[phone]");
//string payload = generator.ToString();

//普通字符串的二维码
string payload = "第一张二维码图片";
QRCodeGenerator qRCodeGenerator = new QRCodeGenerator();
QRCodeData qRCodeData = qRCodeGenerator.CreateQrCode(payload, QRCodeGenerator.ECCLevel.Q);
QRCode qRCode = new QRCode(qRCodeData);
Bitmap bitmap = qRCode.GetGraphic(20);
//有图标的二维码
//Bitmap bitmap = qRCode.GetGraphic(20, Color.Black, Color.White, (Bitmap)Bitmap.FromFile(@"D:\1612181843.png"));
bitmap.Save($@"D:\Environment.TickCount.png", System.Drawing.Imaging.ImageFormat.Png);

//释放资源
bitmap.Dispose();
qRCode.Dispose();
qRCodeData.Dispose();
qRCodeGenerator.Dispose();
