Get Mail Merge Field Names

Here is a step-by-step guide to explain the C# source code below, which uses the “Get Merge Field Names” feature of Aspose.Words for .NET. Make sure to follow each step carefully to get the desired results.

Step 1: Document Directory Setup

In the code provided, you must specify the directory of your documents. Replace the value “YOUR DOCUMENT DIRECTORY” with the appropriate path to your documents directory.

string dataDir = "YOUR DOCUMENTS DIRECTORY";

Step 2: Loading the document

The first step is to load the document where you want to get the merge field names.

Document doc = new Document(dataDir + "YOUR DOCUMENT FILE");

Be sure to replace “YOUR DOCUMENT FILE” with the name of your own file.

Step 3: Get merge field names

We use the GetFieldNames() method to get an array containing the names of the merge fields present in the document.

string[] fieldNames = doc.MailMerge.GetFieldNames();

The fieldNames variable now contains the names of the merge fields.

Source Code Example for Get Merge Field Names with Aspose.Words for .NET

// The path to the documents directory.
string dataDir = "YOUR DOCUMENTS DIRECTORY";

// Load the document.
Document doc = new Document(dataDir + "YOUR DOCUMENT FILE");

// Get merge field names.
string[] fieldNames = doc.MailMerge.GetFieldNames();

// Display the number of merge fields.
Console.WriteLine("\nDocument contains " + fieldNames.Length + " merge fields.");

In this example, we loaded a document, got the merge field names using the GetFieldNames() method, and displayed the number of merge fields present in the document.

This concludes our guide on using the “Get Merge Field Names” feature with Aspose.Words for .NET.
