Get the list of Contacts on Windows 10 Phone - xamarin

Question

I am needing to know how to read the contact list on a Windows 10 Phone. I don't want to use a contact picker; I just need to be able to iterate through all contacts to access their name and phone number, and store it in a List. (Similar to how WhatsApp is able to read your contact list and display it in their app)

Answer 1

I've taken some code from another answer here.
With this code you should be able to get the contacts out.
public async Task IterateThroughContactsForContactListId()
{
ContactStore allAccessStore = await ContactManager.RequestStoreAsync(ContactStoreAccessType.AllContactsReadOnly);
var contacts = await allAccessStore.FindContactsAsync();
foreach (var contact in contacts)
{
//process aggregated contacts
if (contact.IsAggregate)
{
//here contact.ContactListId is "" (null....)
//in this case if you need the the ContactListId then you need to iterate through the raw contacts
var rawContacts = await allAccessStore.AggregateContactManager.FindRawContactsAsync(contact);
foreach (var rawContact in rawContacts)
{
//Here you should have ContactListId
Debug.WriteLine($"aggregated, name: {rawContact.DisplayName }, ContactListId: {rawContact.ContactListId}");
}
}
else //not aggregated contacts should work
{
Debug.WriteLine($"not aggregated, name: {contact.DisplayName }, ContactListId: {contact.ContactListId}");
}
}
}
He also notes:
And very important: In the appxmanifest you have to add the contacts
capability. Right click to it in the solution explorer and "View Code"
and then under Capabilities put
<uap:Capability Name="contacts" />
There is no UI for this. See this.
