Examples

Shows how to verify mail merge regions.

Document doc = new Document(MyDir + "Mail merge regions.docx");

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

// Get top regions in the document.
IList<MailMergeRegionInfo> topRegions = regionInfo.Regions;

Assert.AreEqual(2, topRegions.Count);
Assert.AreEqual("Region1", topRegions[0].Name);
Assert.AreEqual("Region2", topRegions[1].Name);
Assert.AreEqual(1, topRegions[0].Level);
Assert.AreEqual(1, topRegions[1].Level);

// Get nested region in first top region.
IList<MailMergeRegionInfo> nestedRegions = topRegions[0].Regions;

Assert.AreEqual(2, nestedRegions.Count);
Assert.AreEqual("NestedRegion1", nestedRegions[0].Name);
Assert.AreEqual("NestedRegion2", nestedRegions[1].Name);
Assert.AreEqual(2, nestedRegions[0].Level);
Assert.AreEqual(2, nestedRegions[1].Level);
Assert.AreEqual(0, nestedRegions[1].MustacheTags.Count);

// Get list of fields inside the first top region.
IList<Field> fieldList = topRegions[0].Fields;

Assert.AreEqual(4, fieldList.Count);

FieldMergeField startFieldMergeField = nestedRegions[0].StartField;

Assert.AreEqual("TableStart:NestedRegion1", startFieldMergeField.FieldName);

FieldMergeField endFieldMergeField = nestedRegions[0].EndField;

Assert.AreEqual("TableEnd:NestedRegion1", endFieldMergeField.FieldName);
