FOREACH Statement available in NAV2016

A very used statement in C# is the foreach statement. A loop that traverse any structure with a enumerator. This is now present in NAV2016, only on dotnet variables so far.

Here is an example from the OCR/Document module of NAV0216.

An outer loop of all the child nodes in a xml node, and the an inner loop of all the “DocumentId” childs of the first node.

FOREACH XMLNode IN XMLRootNode.ChildNodes DO BEGIN
        ChildNode := XMLNode.SelectSingleNode('BatchExternalId');
        ExternalBatchId := ChildNode.InnerText;
        IF (ExternalBatchFilter = '') OR (ExternalBatchFilter = ExternalBatchId) THEN
          FOREACH ChildNode IN XMLNode.SelectNodes('DocumentId') DO BEGIN
            DocId := ChildNode.InnerText;

           

Another example, goes through all the elements of an dotnet Array:

FOREACH Table IN TableList DO BEGIN
        Name := FilterPageBuilder.ADDTABLE(GetTableCaption(Table),Table);
        AddFields(FilterPageBuilder,Name,Table);
END;

So far, it looks like FOREACH is only present in “new” objects in NAV2016.
