VCF Vcard import c# | 易学教程

问题

iam trying to write a class which imports *.vcf files (Vcard), because i didn´t found a adequate .net class to solve that job.

So i decided to treat the *.vcf file like a *.txt file. I just import the whole file, line by line, with a StreamReader. Finally i save the line into a List object.

The Code:

 private List<string> vcardList = new List<String>();
    public Form1()
    {
        InitializeComponent();
    }

    private void Form1_Load(object sender, EventArgs e)
    {
        using (StreamReader reader = new StreamReader(@"H:\VS.vcf"))
        {
            string line;
            while ((line = reader.ReadLine()) != null)
            {
                vcardList.Add(line);
            }
        }
    }

After importing the text i needed to edit the lines, because i need to remove all the unnecessary symbols. I tried to use the RedEx claa:

private void button1_Click(object sender, EventArgs e)
    {
        vcardList[0] = Regex.Replace(vcardList[0], "BEGIN:", string.Empty);          
    }

that works very well, for the first line! but the *.vcf file is very complex and allways different.

So my question is: Is there a better way to solve that problem?

This is the *.vcf file:

BEGIN:VCARD
VERSION:2.1
N;LANGUAGE=de;CHARSET=Windows-1252:Test;Mustermann;;;(geschäftlich)
FN;CHARSET=Windows-1252:Test Mustermann (geschäftlich)

EMAIL;PREF;INTERNET:Test@Test-Mustermann.de

END:VCARD

I only need the name and address. Thanks in advance

Helle, sry for the long delay.

I solved my problem now with the follwing code:

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using Outlook = Microsoft.Office.Interop.Outlook;

namespace WindowsFormsApplication1
{
public partial class Form1 : Form
{
    public Form1()
{
InitializeComponent();
}

    private void Form1_Load(object sender, EventArgs e)
   {
        Outlook.ContactItem contact;
        Outlook.Application app = new Outlook.Application();

        contact = (Outlook.ContactItem)app.Session.OpenSharedItem(@"C:\vv.vfc");
        MessageBox.Show(contact.FirstName);
    }
   }
 }

This is just an example of how to easily import a VCF file with C# . i hope this helps. Of course i wouldnt implement it in that way, i rather would create a method with a parameter "incomingFile" or smth else.

the solution with the outlook application is not effictive.

Outlook.Application app = new Outlook.Application();

this will open the outlook first. and actually you need only to open the vcard and parse it to extract the information you want from it.
