How to: Get FromDate, ToDate in Query range AX 2012 R3

Hi experts,

I want to get FromDate, ToDate like pic below:

I try to use this code:

_QueryBuildDataSource = _QueryRun.query().dataSourceTable(tableNum(ProdTable));
_QueryBuildRange = _QueryBuildDataSource.findRange(fieldNum(ProdTable, FinishedDate));

if(_QueryBuildRange)
info(strFmt("%1", _QueryBuildRange.value()));

--> the result: 01/12/2016..10/04/2017

Anyone has simple solution to help me convert _QueryBuildRange.value() to FromDate, ToDate?

Tks all.
