Reading vCard (.VCF) file information in ASP.Net
Inside the Page Load event handler, 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 are retrieved and set in the respective controls.
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());
}
}
