Rename Merge Fields

Here is a step by step guide to explain the C# source code below which uses the merge field renaming feature of Aspose.Words for .NET. 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: Creating the document and inserting the merge fields

We start by creating a new document and using a DocumentBuilder to insert the merge fields.

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

builder.InsertField(@"MERGEFIELD MyMergeField1 \* MERGEFORMAT");
builder.InsertField(@"MERGEFIELD MyMergeField2 \* MERGEFORMAT");

Step 3: Renaming Merge Fields

We loop through each field in the document range, and if it’s a merge field, we rename the field by adding the “_Renamed” suffix.

foreach(Field f in doc.Range.Fields)
{
     if (f.Type == FieldType.FieldMergeField)
     {
         FieldMergeField mergeField = (FieldMergeField)f;
         mergeField.FieldName = mergeField.FieldName + "_Renamed";
         mergeField.Update();
     }
}

Step 4: Saving the document

Finally, we call the Save() method to save the modified document.

doc.Save(dataDir + "WorkingWithFields.RenameMergeFields.docx");

Source code example for renaming merge fields with Aspose.Words for .NET

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

// Create the document and insert the merge fields.
Document doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);

builder.InsertField(@"MERGEFIELD MyMergeField1 \* MERGEFORMAT");
builder.InsertField(@"MERGEFIELD MyMergeField2 \* MERGEFORMAT");

// Rename merge fields.
foreach(Field f in doc.Range.Fields)
{
     if (f.Type == FieldType.FieldMergeField)
     {
         FieldMergeField mergeField = (FieldMergeField)f;
         mergeField.FieldName = mergeField.FieldName + "_Renamed";
         mergeField.Update();
     }
}

// Save the document.
doc.Save(dataDir + "WorkingWithFields.RenameMergeFields.docx");

Follow these steps to rename merge fields in your document using Aspose.Words for .NET.
