FieldMergeSeq class

Implements the MERGESEQ field.

public class FieldMergeSeq : Field


Name Description
FieldMergeSeq() The default constructor.


Name Description
DisplayResult { get; } Gets the text that represents the displayed field result.
End { get; } Gets the node that represents the field end.
Format { get; } Gets a FieldFormat object that provides typed access to field’s formatting.
IsDirty { get; set; } Gets or sets whether the current result of the field is no longer correct (stale) due to other modifications made to the document.
IsLocked { get; set; } Gets or sets whether the field is locked (should not recalculate its result).
LocaleId { get; set; } Gets or sets the LCID of the field.
Result { get; set; } Gets or sets text that is between the field separator and field end.
Separator { get; } Gets the node that represents the field separator. Can be null.
Start { get; } Gets the node that represents the start of the field.
virtual Type { get; } Gets the Microsoft Word field type.


Name Description
GetFieldCode() Returns text between field start and field separator (or field end if there is no separator). Both field code and field result of child fields are included.
GetFieldCode(bool) Returns text between field start and field separator (or field end if there is no separator).
Remove() Removes the field from the document. Returns a node right after the field. If the field’s end is the last child of its parent node, returns its parent paragraph. If the field is already removed, returns null.
Unlink() Performs the field unlink.
Update() Performs the field update. Throws if the field is being updated already.
Update(bool) Performs a field update. Throws if the field is being updated already.


At the moment the MERGEREC and MERGESEQ fields implement the same functionality because we don’t know for sure how to skip records in Aspose.Words mail merge.


Shows how to use MERGEREC and MERGESEQ fields to the number and count mail merge records in a mail merge’s output documents.

Document doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);

builder.Write("Dear ");
FieldMergeField fieldMergeField = (FieldMergeField)builder.InsertField(FieldType.FieldMergeField, true);
fieldMergeField.FieldName = "Name";

// A MERGEREC field will print the row number of the data being merged in every merge output document.
builder.Write("\nRow number of record in data source: ");
FieldMergeRec fieldMergeRec = (FieldMergeRec)builder.InsertField(FieldType.FieldMergeRec, true);

Assert.AreEqual(" MERGEREC ", fieldMergeRec.GetFieldCode());

// A MERGESEQ field will count the number of successful merges and print the current value on each respective page.
// If a mail merge skips no rows and invokes no SKIP/SKIPIF/NEXT/NEXTIF fields, then all merges are successful.
// The MERGESEQ and MERGEREC fields will display the same results of their mail merge was successful.
builder.Write("\nSuccessful merge number: ");
FieldMergeSeq fieldMergeSeq = (FieldMergeSeq)builder.InsertField(FieldType.FieldMergeSeq, true);

Assert.AreEqual(" MERGESEQ ", fieldMergeSeq.GetFieldCode());

// Insert a SKIPIF field, which will skip a merge if the name is "John Doe".
FieldSkipIf fieldSkipIf = (FieldSkipIf)builder.InsertField(FieldType.FieldSkipIf, true);
fieldMergeField = (FieldMergeField)builder.InsertField(FieldType.FieldMergeField, true);
fieldMergeField.FieldName = "Name";
fieldSkipIf.LeftExpression = "=";
fieldSkipIf.RightExpression = "John Doe";

// Create a data source with 3 rows, one of them having "John Doe" as a value for the "Name" column.
// Since a SKIPIF field will be triggered once by that value, the output of our mail merge will have 2 pages instead of 3.
// On page 1, the MERGESEQ and MERGEREC fields will both display "1".
// On page 2, the MERGEREC field will display "3" and the MERGESEQ field will display "2".
DataTable table = new DataTable("Employees");
table.Rows.Add(new[] { "Jane Doe" });
table.Rows.Add(new[] { "John Doe" });
table.Rows.Add(new[] { "Joe Bloggs" });

doc.Save(ArtifactsDir + "Field.MERGEREC.MERGESEQ.docx");
