How to merge several times

our need is to build a template doc with merge fields and to be able to update the value of these fields several times.
For example we get a template document with a merge field named “version_number”.
At a first time we merge the template to generate a .docx with “1” as value for version_number, then we modify the .docx by adding a new chapter … and then we want to merge again this modified docx with 2 as value for version_number.
that means to keep the merge informations in the docx to be able to merge it several times …
Is it possible ?
Thanks in advance for your help

What is the best solution ?


Thanks for your inquiry. Please note that Aspose.Words for .NET is a class library that enables your applications to perform a great range of document processing tasks. Aspose.Words does not provide any UI to insert the mail merge field. However, you can programmatically insert the mail merge field using Aspose.Words. Please check the following code example.

Document doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);
builder.InsertField(@"MERGEFIELD MyMergeField1 \* MERGEFORMAT");
builder.InsertField(@"MERGEFIELD MyMergeField2 \* MERGEFORMAT");
