Question

The problem I want to solve: Get all the contacts info like name and Mobile phone and write it into file and save in ISO.

How to use SearchAsync if I want to search available contacts in the phone?
How to iterate the return-results and write to file one by one of the contact into a file?

这里,我有:

private void btnSearch_Click(object sender, RoutedEventArgs e)
{    
    Contacts contacts = new Contacts();     
    contacts.SearchCompleted += new EventHandler<ContactsSearchEventArgs>(contacts_SearchCompleted);   
    contacts.SearchAsync(displayName,FilterKind.DisplayName,null);    
    //search for all contacts   
    contacts.SearchAsync(string.Empty, FilterKind.None, null);
}

<>Update:

如果电话公司是雇佣公司,则以下代码将产生NllException错误。为什么?

利用这一途径在电话中搜寻所有联系人:

contacts.SearchAsync(searchterm, FilterKind.None, null);

void contacts_SearchCompleted(object sender, ContactsSearchEventArgs e)
{
    int intTTL = e.Results.Count();
    if (intTTL != 0)
    {
        MessageBox.Show(intTTL.ToString());
        foreach (var result in e.Results)
        {
            string strTTL;
            string strName = result.DisplayName;
            string MobileNo = result.PhoneNumbers.FirstOrDefault().ToString();
            strTTL = strName + "," + MobileNo;
            MessageBox.Show(strTTL);
        }
    else
    {
        MessageBox.Show("You have not entered any contact info at all.");
    }
}

查阅。

1. 核准:

void contacts_SearchCompleted(object sender, ContactsSearchEventArgs e)
{
    foreach(var contact in e.Results)
    {
        // write to Isolated storage
    }
}
