Read and Import vCard (.VCF) file information using C# and VB.Net
 
 
Thought Project vCard Library
I am making use of the Thought Project vCard Library for reading vCard. You can download the file from the following location.
 
 
HTML Markup
The following HTML Markup consists of an Image and some Label controls for displaying the imported information from the vCard file.
<table border="0" cellpadding="0" cellspacing="0">
    <tr>
        <td rowspan="10" valign="top">
            <asp:Image ID="imgPhoto" runat="server" />
        </td>
    </tr>
    <tr>
        <td style="width: 100px">
            Name:
        </td>
        <td>
            <asp:Label ID="lblName" runat="server" />
        </td>
    </tr>
    <tr>
        <td style="width: 100px">
            Company Name:
        </td>
        <td>
            <asp:Label ID="lblOrganization" runat="server" />
        </td>
    </tr>
    <tr>
        <td>
            Mobile Number:

Namespaces
You will need to import the following namespaces.
C#
using Thought.vCards;
 
VB.Net
Imports Thought.vCards
 
 
Read, Import and Display vCard (.VCF) file information in ASP.Net
Inside the Page Load event of ASP.Net Page, the vCard file is read into a vCard object. Once the vCard object is populated, the information such as Name, Organization, Phone Numbers, Email Addresses, Websites and Photo of the contact can be read and displayed.
C#
protected void Page_Load(object sender, EventArgs e)
{
    //Read the vCard file into a vCard object.
    vCard card = new vCard(Server.MapPath("~/vCards/Mudassar Khan.vcf"));
 
    //Read Name.
    lblName.Text = card.FormattedName;
 
    //Read Organization.
    lblOrganization.Text = card.Organization;
 
    //Read Title.
    lblTitle.Text = card.Title;
 
    //Read Cell Phone Number.
    if (card.Phones.GetFirstChoice(vCardPhoneTypes.Cellular) != null)
    {
        lblMobileNumber.Text = card.Phones.GetFirstChoice(vCardPhoneTypes.Cellular).FullNumber;
    }
 
    //Read Home Number.
    if (card.Phones.GetFirstChoice(vCardPhoneTypes.Home) != null)
    {
        lblHomeNumber.Text = card.Phones.GetFirstChoice(vCardPhoneTypes.Home).FullNumber;
    }
 
    //Read Work Number.
    if (card.Phones.GetFirstChoice(vCardPhoneTypes.Work) != null)
    {
        lblWorkNumber.Text = card.Phones.GetFirstChoice(vCardPhoneTypes.Work).FullNumber;
    }
 
    //Read Email Address.
    if (card.EmailAddresses.GetFirstChoice(vCardEmailAddressType.Internet) != null)
    {
        lblEmailAddress.Text = card.EmailAddresses.GetFirstChoice(vCardEmailAddressType.Internet).Address;
    }
 
    //Read Website URL.
    if (card.Websites.GetFirstChoice(vCardWebsiteTypes.Personal) != null)
    {
        lblWebsite.Text = card.Websites.GetFirstChoice(vCardWebsiteTypes.Personal).Url;
    }
 
    //Read Photo.
    if (card.Photos.Count > 0)
    {
        imgPhoto.ImageUrl = "data:image/png;base64," + Convert.ToBase64String(card.Photos[0].GetBytes());
    }
}
 
VB.Net
Protected Sub Page_Load(sender As Object, e As EventArgs) Handles Me.Load
