在Unity创建如下界面：

生成二维码脚本如下：

using UnityEngine;
using System.Collections;
using ZXing;
using ZXing.QrCode;
using UnityEngine.UI;

public class Demo : MonoBehaviour 
{
    //需要生产二维码的字符串
    string QrCodeStr;

    //在屏幕上显示二维码
    public RawImage image;

    //存放二维码
    Texture2D encoded; 

	// Use this for initialization
	void Start () {
        encoded = new Texture2D(256, 256); 
	}
	
	// Update is called once per frame
	void Update () {

	}

    //定义方法生成二维码  
    private static Color32[] Encode(string textForEncoding, int width, int height)
    {
        var writer = new BarcodeWriter
        {
            Format = BarcodeFormat.QR_CODE,
            Options = new QrCodeEncodingOptions
            {
                Height = height,
                Width = width
            }
        };
        return writer.Write(textForEncoding);
    }


    /// <summary>
    /// 生成二维码
    /// </summary>
    public void Btn_CreatQr() 
    {
        QrCodeStr = GameObject.Find("InputField").GetComponent<InputField>().text;
        if (QrCodeStr.Length > 1)
        {
            //二维码写入图片  
            var color32 = Encode(QrCodeStr, encoded.width, encoded.height);
            encoded.SetPixels32(color32);
            encoded.Apply();
            //生成的二维码图片附给RawImage  
            image.texture = encoded;
        }
        else 
        {
            GameObject.Find("InputField").GetComponent<InputField>().text = "没有生成信息";
        }
    }
}
