Generating a two-dimensional code C # (with Logo)

Generating a two-dimensional code C # (with Logo)

The first way

We need to reference ThoughtWorks.QRCode.dll generate two-dimensional code with a logo (framework4.0 above)

The second way

We need to reference  Gma.QrCodeNet.Encoding.Net45.dll   (framework4.5 above) to support Chinese
