foreach loop question

[jcast]

I have this foreach statement to filter from my list of address (addressinfo) the ones that doesnt have the flag deleted on DB.

var accountSvc = new AccountSvc();
var personInfo = accountSvc.GetProfileInfo(AccountPhone);
var addressInfo = accountSvc.GetPersonAddresses(personInfo.Id);

if (repAddresses != null)
foreach (var add in addressInfo)
if (add.Deleted == false || add.Deleted == null)
{
var personSvc = new Shared.Core.Person.PersonSvc();
var address = personSvc.GetAddressProfile(add.AddressId);
// addressInfo = address;
}

repAddresses.DataSource = addressInfo;
repAddresses.DataBind();

if I do addessInfo = address I will get only the last address in loop, how can I save each address that go thru the loop and return them all.

Thanks

You can use Linq/Lambda Expressions (if you are using .NET 4.0)

var activeAddresses = addressInfo.Where(add => add.Deleted == false || add.Deleted == null)

foreach (add in activeAddresses)
{
   // Do Processing on the addresses
}

If you aren't using .NET 4.0, then you can create a new list containing only the active addresses as you loop through.

List<AddressInfoType> activeAddresses = new List<AddressInfoType>(); //*

foreach (var add in addressInfo)
{
  if (add.Deleted == false || add.Deleted == null)
  {
    var personSvc = new Shared.Core.Person.PersonSvc();
    var address = personSvc.GetAddressProfile(add.AddressId);
    
    activeAddresses.Add(address);
  }
}

*Note - Replace AddressInfoType with the actual DataType of addressInfo.

The foreach loop is useful for traversing each items in an array or a collection of items and displayed one by one.

for each syntax is

foreach(variable type in collection){
// code block
}
