C # zxing.net generates two-dimensional code, identifies two-dimensional code, and generates a two-dimensional code with a logo (ii)

1. Use zxint.net to generate a QR code with logo

/// <summary>///Create a QR code with logo/// </summary>/// <param name= "text" ></param>Static voidGenerate3 (stringtext) {    //Logo ImageBitmap logo =NewBitmap (@"h:\ Desktop \\102.jpg"); //construction of two-dimensional code write code deviceMultiformatwriter writer =NewMultiformatwriter (); Dictionary<encodehinttype,Object> hint =NewDictionary<encodehinttype,Object>(); Hint.
