System::SharedPtr<Aspose::Words::MailMerging::MailMergeRegionInfo> Aspose::Words::MailMerging::MailMerge::GetRegionsHierarchy()

ReturnValue

Regions’ hierarchy.

Remarks

Hierarchy is returned in the form of the MailMergeRegionInfo class.

Examples

Shows how to verify mail merge regions.

auto doc = MakeObject<Document>(MyDir + u"Mail merge regions.docx");

// Returns a full hierarchy of merge regions that contain MERGEFIELDs available in the document.
SharedPtr<MailMergeRegionInfo> regionInfo = doc->get_MailMerge()->GetRegionsHierarchy();

// Get top regions in the document.
SharedPtr<System::Collections::Generic::IList<SharedPtr<MailMergeRegionInfo>>> topRegions = regionInfo->get_Regions();

ASSERT_EQ(2, topRegions->get_Count());
ASSERT_EQ(u"Region1", topRegions->idx_get(0)->get_Name());
ASSERT_EQ(u"Region2", topRegions->idx_get(1)->get_Name());
ASSERT_EQ(1, topRegions->idx_get(0)->get_Level());
ASSERT_EQ(1, topRegions->idx_get(1)->get_Level());

// Get nested region in first top region.
SharedPtr<System::Collections::Generic::IList<SharedPtr<MailMergeRegionInfo>>> nestedRegions = topRegions->idx_get(0)->get_Regions();

ASSERT_EQ(2, nestedRegions->get_Count());
ASSERT_EQ(u"NestedRegion1", nestedRegions->idx_get(0)->get_Name());
ASSERT_EQ(u"NestedRegion2", nestedRegions->idx_get(1)->get_Name());
ASSERT_EQ(2, nestedRegions->idx_get(0)->get_Level());
ASSERT_EQ(2, nestedRegions->idx_get(1)->get_Level());

// Get list of fields inside the first top region.
SharedPtr<System::Collections::Generic::IList<SharedPtr<Field>>> fieldList = topRegions->idx_get(0)->get_Fields();

ASSERT_EQ(4, fieldList->get_Count());

SharedPtr<FieldMergeField> startFieldMergeField = nestedRegions->idx_get(0)->get_StartField();

ASSERT_EQ(u"TableStart:NestedRegion1", startFieldMergeField->get_FieldName());

SharedPtr<FieldMergeField> endFieldMergeField = nestedRegions->idx_get(0)->get_EndField();

ASSERT_EQ(u"TableEnd:NestedRegion1", endFieldMergeField->get_FieldName());
