如何以.VCF格式保存联系人 [英] How to save contacts in the .VCF format
问题描述
我有一个用于保存数据的类和该类的列表。
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的内容写入该实例。
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< File的a href = http://msdn.microsoft.com/zh-cn/library/system.io.file.writealltext.aspx rel = noreferrer> WriteAllText (...)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。
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
