【问题描述】：
我正在尝试通过 xamarin c# 在 android 中添加具有多个电话号码的联系人。这是我要添加联系人的按钮。
我尝试了从传递数组到尝试单独添加第二个数字的所有方法，但后一种解决方案只是在实际保存之前覆盖第一个数字（如怀疑的那样）。
我在某处（可能在 xamarin 论坛上）读到，在 Xamarin.ios 中，我们可以一次性将所有电话号码添加为数组。
private void test_Click(object sender, EventArgs e)
{
List<ContentProviderOperation> ops = new List<ContentProviderOperation>();
ContentProviderOperation.Builder builder =
ContentProviderOperation.NewInsert(RawContacts.ContentUri);
builder.WithValue(RawContacts.InterfaceConsts.AccountType, null);
builder.WithValue(RawContacts.InterfaceConsts.AccountName, null);
ops.Add(builder.Build());
//Name
builder = ContentProviderOperation.NewInsert(Data.ContentUri);
builder.WithValueBackReference(Data.InterfaceConsts.RawContactId, 0);
builder.WithValue(Data.InterfaceConsts.Mimetype,
StructuredName.ContentItemType);
builder.WithValue(StructuredName.FamilyName, "Added fname");
builder.WithValue(StructuredName.GivenName, "firstName");
ops.Add(builder.Build());
List<string> a = new List<string>();
a.Add("89892302398");
a.Add("93823239232");
//Number
builder = ContentProviderOperation.NewInsert(Data.ContentUri);
builder.WithValueBackReference(Data.InterfaceConsts.RawContactId, 0);
builder.WithValue(Data.InterfaceConsts.Mimetype,
cont.ContentItemType);
builder.WithValue(cont.Number,"83293982" ); //tried to pass array here a.ToArray()
builder.WithValue(cont.InterfaceConsts.Type,
cont.InterfaceConsts.TypeCustom);
builder.WithValue(cont.InterfaceConsts.Label, "Work");
builder.WithValue(cont.InterfaceConsts.Number, "808004038");
builder.WithValue(cont.InterfaceConsts.Type,
cont.InterfaceConsts.TypeCustom);
builder.WithValue(cont.InterfaceConsts.Label, "Home");
ops.Add(builder.Build());
//Add the new contact
ContentProviderResult[] res;
try
{
res = ContentResolver.ApplyBatch(Authority, ops);
Toast.MakeText(this, "contact saved !", ToastLength.Short).Show();
}
catch
{
Toast.MakeText(this, "contact not saved_message !", ToastLength.Long).Show();
}
}
在我的项目中，我试图从我之前创建的 csv 文件中恢复联系人，但唯一的问题是我无法保存具有多个号码的联系人。我应该看起来像：
How I want the contact to look like after it's added
更新： 这就是我的完整功能的样子：
//Restore Contacts
private void CreateCon_Click(object sender, EventArgs e)
{
try
{
Toast.MakeText(this, "Create Contact Clicked", ToastLength.Short).Show();
// TextView txtv = FindViewById<TextView>(Resource.Id.txt);

double loop;
Boolean boo;
s.GetLoopTimes("contacts", PhoneNumbers[0], out loop, out boo);
Toast.MakeText(this, "loops : " + loop, ToastLength.Short).Show();
for (int ij = 0; ij < loop; ij++)
{
ex_cons = ex_cons.Union(s.GetContacts(PhoneNumbers[0])).ToList();
}
Android.Net.Uri uri = contact.ContentUri;
Android.Net.Uri uri2 = cont.ContentUri;
string[] projection =

contact.InterfaceConsts.Id,

contact.InterfaceConsts.ContactLastUpdatedTimestamp
};
string[] projection2 =

cont.InterfaceConsts.ContactId,
cont.Number,
cont.InterfaceConsts.Type,

loader = new CursorLoader(this, uri, projection, null, null, "contact_last_updated_timestamp Asc");
var cursor = (ICursor)loader.LoadInBackground();

string name = cursor.GetString(cursor.GetColumnIndex(projection[1]));
string date = cursor.GetString(cursor.GetColumnIndex(projection[2]));

{
List<string> temp_no = new List<string>();
List<string> temp_type_list = new List<string>();
List<string> temp_numbers_list = new List<string>();
do
{
string number = cursor2.GetString(cursor2.GetColumnIndex(projection2[1]));
//string numb = number; // used so that original spaces and all for unique contacts can be maintained...just replace numb with number if you don't want it. for eg. 95-9223-5321 can be stored as it is
int typ = cursor2.GetInt(cursor2.GetColumnIndex(projection2[2]));
string temp_type = typ.ToString();

}
int i = 1;
foreach(var single_con in ex_cons)
