部分数据从下面这个链接来的，只是觉得代码比较冗余，所以........

想看的可以去看下：

C# 生成联系人二维码_勇敢小菜鸟的博客-CSDN博客NuGet 引用库不废话贴代码:using Gma.QrCodeNet.Encoding;using Gma.QrCodeNet.Encoding.Windows.Render;using System;using System.Collections.Generic;using System.Drawing;using System.Drawing.Imaging;using System.IO;using System.Linq;using System.Text;usin.https://blog.csdn.net/u010209404/article/details/112574238

一、安装和效果图展示

后台安装Gma.QrCodeNet的Nuget包

VCard格式：

BEGIN:VCARD
VERSION:2.1
N:Gump;Forrest
FN:Forrest Gump
ORG:Gump Shrimp Co.
TITLE:Shrimp Man
TEL;WORK;VOICE:(111) 555-1212
TEL;HOME;VOICE:(404) 555-1212
ADR;WORK:;;100 Waters Edge;Baytown;LA;30314;United States of America
LABEL;WORK;ENCODING=QUOTED-PRINTABLE:100 Waters Edge=0D=0ABaytown, LA 30314=0D=0AUnited States of America

EMAIL;PREF;INTERNET:forrestgump@walladalla.com
REV:20080424T195243Z
END:VCARD

可以直接到草料网查看格式：

二维码扫码能看到效果图，如下：

二、贴后台代码

1.我这里是做保存二维码到桌面的，所以是直接生成二维码如何保存为一张图片了


/// <summary>
/// 生成VCard二维码
/// </summary>
/// <param name="url">数据路径</param>
///<returns></returns>
public string CreateGmaQrCodeNet(jrgt_mybusinesscard data)
{//这两个字段应该是必须要有的 这里我没测试if (string.IsNullOrWhiteSpace(data.myname) || string.IsNullOrWhiteSpace(data.myphone))return "please input Name and Tels value";var result = new StringBuilder();result.AppendLine("BEGIN:VCARD VERSION:3.0");//这个注释或者不注释好像都没报错信息的//result.AppendLine($"N:;{data.myname};;;");result.AppendLine($"FN:{data.myname}");if (!string.IsNullOrWhiteSpace(data.job))result.AppendLine($"TITLE:{data.job}");if (!string.IsNullOrWhiteSpace(data.myphone))result.AppendLine($"TEL;WORK;VOICE:{data.myphone}");if (!string.IsNullOrWhiteSpace(data.mypost))result.AppendLine($"EMAIL;PREF;INTERNET:{data.mypost}");if (!string.IsNullOrWhiteSpace(data.inst_name))result.AppendLine($"ORG:{data.inst_name}");if (!string.IsNullOrWhiteSpace(data.inst_address))result.AppendLine($"ADR;WORK:{data.inst_address}");result.AppendLine("END:VCARD");using (var ms = new MemoryStream()){string vcard = result.ToString();var encoder = new QrEncoder(ErrorCorrectionLevel.M);if (encoder.TryEncode(vcard, out QrCode qrCode)){var gRenderer = new GraphicsRenderer(new FixedModuleSize(2, QuietZoneModules.Two), Brushes.Black, Brushes.White);gRenderer.WriteToStream(qrCode.Matrix, ImageFormat.Png, ms);Image img = Image.FromStream(ms);//保存图片var filePath = @"C:\Users\admin\Desktop\112233\HelloWorld.png";img.Save(filePath, ImageFormat.Png);return "";}}
}

直接生成的二维码：

扫码安卓和ios的效果不同，图一安卓，图二ios，字段我只列了自己需要的字段

2.可以返回为Image格式值，然后接收生成二维码展示


/// <summary>
/// 生成VCard二维码
/// </summary>
/// <param name="url">数据路径</param>
///<returns></returns>
public Image CreateGmaQrCodeNet(jrgt_mybusinesscard data)
{if (string.IsNullOrWhiteSpace(data.myname) || string.IsNullOrWhiteSpace(data.myphone))throw new ValidateException("please input Name and Tels value");var result = new StringBuilder();result.AppendLine("BEGIN:VCARD VERSION:3.0");//result.AppendLine($"N:;{data.myname};;;");result.AppendLine($"FN:{data.myname}");if (!string.IsNullOrWhiteSpace(data.job))result.AppendLine($"TITLE:{data.job}");if (!string.IsNullOrWhiteSpace(data.myphone))result.AppendLine($"TEL;WORK;VOICE:{data.myphone}");if (!string.IsNullOrWhiteSpace(data.mypost))result.AppendLine($"EMAIL;PREF;INTERNET:{data.mypost}");if (!string.IsNullOrWhiteSpace(data.inst_name))result.AppendLine($"ORG:{data.inst_name}");if (!string.IsNullOrWhiteSpace(data.inst_address))result.AppendLine($"ADR;WORK:{data.inst_address}");result.AppendLine("END:VCARD");using (var ms = new MemoryStream()){string vcard = result.ToString();var encoder = new QrEncoder(ErrorCorrectionLevel.M);if (encoder.TryEncode(vcard, out QrCode qrCode)){var gRenderer = new GraphicsRenderer(new FixedModuleSize(2, QuietZoneModules.Two), Brushes.Black, Brushes.White);gRenderer.WriteToStream(qrCode.Matrix, ImageFormat.Png, ms);Image img = Image.FromStream(ms);//保存图片//var filePath = @"C:\Users\admin\Desktop\112233\HelloWorld.png";//img.Save(filePath, ImageFormat.Png);return img;}elsereturn null;}
}

接收VCard二维码，返回


/// <summary>

}
