How. NET parses two-dimensional code images

QR code is now more and more popular, you can use the phone or other mobile terminals on the QR code scanner software to scan the QR code, you can get relevant information. In the Internet site, you can find a lot of QR code tools, and even a lot of online generation, parsing QR code of the site. In the business system, such as the file management system, previously generally through the barcode (one-dimensional code) to store the basic information of staff, but the storage capacity is limited. You can now use the QR code to store more capacity information.
We use the ThoughtWorks.QRCode.dll class library, which is referenced in an ASP. NET project, and can be developed using the relevant API.

For example, we encapsulate one of the most streamlined classes:

Help class:

[CSharp]/// <summary>          ///Search QR Code helper class/// /// </summary>          ///Public class Qrcodeop {/// <summary>              ///generate two-dimensional code/// </summary>              /// <param name= "Qrcodecontent" >the content to encode</param>              //<returns> return QR code bitmap </returns>         Public StaticBitmap Qrcodeencoderutil (stringqrcodecontent) {Qrcodeencoder Qrcodeencoder=NewQrcodeencoder (); Qrcodeencoder.qrcodeversion=0; Bitmap img= Qrcodeencoder.encode (qrcodecontent, Encoding.UTF8);//Specify UTF-8 encoding, support Chinese            returnimg; }        /// <summary>              ///parsing two-dimensional code/// </summary>              /// <param name= "Bitmap" >Two-dimensional code bitmap to parse</param>              /// <returns>parsed String</returns>              Public Static stringQrcodedecoderutil (Bitmap Bitmap) {Qrcodedecoder decoder=NewQrcodedecoder (); stringDecodedString = Decoder.decode (NewQrcodebitmapimage (bitmap), Encoding.UTF8);//Specify UTF-8 encoding, support Chinese            returndecodedstring; }
