Reading and Importing vCard (.VCF) file information in ASP.Net

Inside the Page_Load event handler, the vCard (.VCF) class object is created and path of the vCard file is passed as parameter to it.
The information such as Name, Organization, Phone Numbers, Email Addresses, Websites, Photo and etc. of the contact are retrieved and set in their respective Label.
Then, a check is performed if Information such as Phone Numbers, Email Addresses and Websites is present in the vCard (.VCF) file, if present then it is set to their respective Label.
After that, if photo count is greater than 0 then BYTE Array is determined using GetBytes method and converted to BASE64 string and assigned to the ImageUrl property of the Image control.
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
