如何以 .VCF 格式保存联系人 [英] How to save contacts in the .VCF format

问题描述

我有一个类来保存数据和该类的列表.这是我的代码.

I have a class to hold data and a list of that class. Here is my code.

static void Main(string[] args)
    {
        List<GoogleContacts> contacts = new List<GoogleContacts>();
        contacts.Add(new GoogleContacts { title = "A", email = "B", im = "X" });
        contacts.Add(new GoogleContacts { title = "C", email = "D", im = "Y" });
        contacts.Add(new GoogleContacts { title = "E", email = "F", im = "Z" });
    }
}


public class GoogleContacts
{
    public string title { get; set; }
    public string email { get; set; }
    public string im { get; set; }
}

我想将这些数据保存在本地磁盘的 .VCF 文件中.

I want to save those data in a .VCF file in local Disk.

推荐答案

只需创建一个 StringBuilder 实例并将 .VCF 的内容写入其中即可.

Just create a StringBuilder instance and write the contents of the .VCF to it.

var contact = new GoogleContacts() { ... };

var vcf = new StringBuilder();
vcf.Append("TITLE:" + contact.Title + System.Environment.NewLine); 
//...

之后，您可以使用静态 WriteAllText(...) 文件类型的方法.

Afterwards you can save it to a file using the static WriteAllText(...) method of the File type.

var filename = @"C:mycontact.vcf";
File.WriteAllText(filename, vcf.ToString());

只需使用文本编辑器打开 .vcf 文件即可浏览其内容.由于您只需要几个属性，因此应该很容易弄清楚.

Just open a .vcf file with a text editor to explore its contents. Since you only require a couple of properties it should be easy to figure out.

一个小例子:

BEGIN:VCARD
FN:Mr. John Smith
TITLE:Developer
ORG:Microsoft
BDAY:1979-12-10
VERSION:2.1
END:VCARD
