Mail Merge in Word with C# and VB.NET

Mail merge is the process of merging or importing data from a data source to a Word document. With GemBox.Document you can do a mail merge programmatically, using C# and VB.NET. In essence, the process involves replacing the Field elements of the MergeField type with values from from provided objects.

GemBox.Document exposes all mail merge related operations and options through the DocumentModel.MailMerge property.

You can read the complete documentation on the Mail Merge help page.

The following example shows how you can perform a simple mail merge by importing data from an anonymous type object.
