DOTNET foreach

Hi

I have this .NET code :

foreach (DataRow JournalDR in objJournal.GetAllNonSyncedJournalsAndNonProcessed().Rows)

Can I "convert" it to NAV 2016.. somehow

Thanks.

create variable for JournalDR of dotnet dataype DataRow

FOREACH JournalDR IN objJournal.GetAllNonSyncedJournalsAndNonProcessed().Rows DO
BEGIN
//your code.
end;

You need to either use the Item property or something similar (see https://msdn.microsoft.com/en-us/library/hh165881(v=nav.90).aspx), or use an enumerator object.

Below is an example where I search a Dictionary for a Value to get back the Key:

VAR
  TableDict@1000000000 : DotNet "'mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'.System.Collections.Generic.Dictionary`2";
PROCEDURE TableNameFromID@1000000007(TableNo@1000000000 : Integer) Name : Text;
VAR
  Enum@1000000003 : DotNet "'mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'.System.Collections.Generic.Dictionary`2+Enumerator";
  KeyVal@1000000002 : DotNet "'mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'.System.Collections.Generic.KeyValuePair`2";
  FieldNoDict@1000000004 : DotNet "'mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'.System.Collections.Generic.Dictionary`2";
  No@1000000005 : Integer;
BEGIN
  IF ISNULL(TableDict) THEN
    FillTableDict;

  Enum := TableDict.GetEnumerator;
  WHILE Enum.MoveNext DO BEGIN
    KeyVal := Enum.Current;
    No := KeyVal.Value;
    IF No = TableNo THEN
      EXIT(KeyVal.Key);
  END;
  EXIT(FORMAT(TableNo));
END;

NAV 2016 has FOREACH and you can use it for dotnet types.

Hi ara3n

Yes, i know
but I can't figure out how to use it like :

foreach (DataRow JournalDR in objJournal.GetAllNonSyncedJournalsAndNonProcessed().Rows)

create variable for JournalDR of dotnet dataype DataRow

FOREACH JournalDR IN objJournal.GetAllNonSyncedJournalsAndNonProcessed().Rows DO
BEGIN
//your code.
end;
