Copy Header/Footer between Word Documents in C#, VB.NET
2015-11-11 06:02:54 Written by support iceblueWhen you create several Word documents that are closely related, you may want the header or footer of one document to be used as the header or footer of other documents. For example, you're creating internal documents with your company logo or name or other material been placed in header, you only have to create the header once and copy the header to other places.
In this article, I'll introduce you a simple and efficient solution to copy the entire header (including text and graphic) from one Word document and insert it to another.
Source Document:
Detail Steps:
Step 1: Create a new instance of Document class and load the source file.
Document doc1 = new Document();
doc1.LoadFromFile("test1.docx");
Step 2: Get the header section from the source document.
HeaderFooter header = doc1.Sections[0].HeadersFooters.Header;
Step 3: Initialize a new instance of Document and load another file that you want to insert header.
Document doc2 = new Document("test2.docx");
Step 4: Call DocuentObject.Clone() method to copy each object in the header of source file, then call DocumentObjectCollection.Add() method to insert copied object into the header of destination file.
foreach (Section section in doc2.Sections)
{
foreach (DocumentObject obj in header.ChildObjects)
{
section.HeadersFooters.Header.ChildObjects.Add(obj.Clone());
}
}
Step 5: Save the changes and launch the file.
doc2.SaveToFile("test2.docx", FileFormat.Docx2013);
System.Diagnostics.Process.Start("test2.docx");
Destination Document:

{
foreach (DocumentObject obj in header.ChildObjects)
{
section.HeadersFooters.Header.ChildObjects.Add(obj.Clone());
}
}
doc2.SaveToFile("test2.docx", FileFormat.Docx2013);
System.Diagnostics.Process.Start("test2.docx");
Dim doc1 As New Document()
doc1.LoadFromFile("test1.docx")
Dim header As HeaderFooter = doc1.Sections(0).HeadersFooters.Header
Dim doc2 As New Document("test2.docx")
For Each section As Section In doc2.Sections
For Each obj As DocumentObject In header.ChildObjects

Sometimes, we need to copy the data with formatting from one cell range (a row or a column) to another. It is an extremely easy work in MS Excel, because we can select the source range and then use Copy and Paste function to insert the same data in destination cells.
In fact, Spire.XLS has provided two methods Worksheet.Copy(CellRange sourceRange, CellRange destRange, bool copyStyle) and Worksheet.Copy(CellRange sourceRange, Worksheet worksheet, int destRow, int destColumn, bool copyStyle) that allow programmers to copy rows and columns within or between workbooks. This article will present how to duplicate a row within a workbook using Spire.XLS.
Test File:
Code Snippet:
Step 1: Create a new instance of Workbook class and load the sample file.
Workbook book = new Workbook();
book.LoadFromFile("sample.xlsx", ExcelVersion.Version2010);
Step 2: Get the first worksheet.
Worksheet sheet = book.Worksheets[0];
Step 3: Call Worksheet.Copy(CellRange sourceRange, CellRange destRange, bool copyStyle) method to copy data from source range (A1:G1) to destination range (A4:G4) and maintain the formatting.
sheet.Copy(sheet.Range["A1:G1"], sheet.Range["A4:G4"],true);
Step 4: Save and launch the file.
book.SaveToFile("result.xlsx", ExcelVersion.Version2010);
System.Diagnostics.Process.Start("result.xlsx");

The following steps explain how to change the page size of a Word document to a standard page size using Spire.Doc for .NET:
- Initialize an instance of the Document class.
- Load a Word document using the Document.LoadFromFile() method.
- Iterate through the sections in the document.
- Adjust the page size of each section to a standard page size by setting the value of the Section.PageSetup.PageSize property to a constant value of the PageSize enum.
- Save the result document using the Document.SaveToFile() method.
- C#
- VB.NET
using Spire.Doc;
using Spire.Doc.Documents;
namespace ChangePageSizeToStandardSize
{
internal class Program
{
static void Main(string[] args)
{
//Initialize an instance of the Document class
Document doc = new Document();
//Load a Word document
doc.LoadFromFile("Input.docx");
//Iterate through the sections in the document
foreach (Section section in doc.Sections)
{
//Change the page size of each section to A4
section.PageSetup.PageSize = PageSize.A4;
}
//Save the result document
doc.SaveToFile("StandardSize.docx", FileFormat.Docx2016);
}
}
}
Adjust the Page Size of a Word Document to a Custom Page Size in C# and VB.NET
If you plan to print your document on paper with dimensions that don't match any standard paper size, you can change the page size of your document to a custom page size that matches the exact dimensions of the paper. The following steps explain how to change the page size of a Word document to a custom page size using Spire.Doc for .NET:
- Initialize an instance of the Document class.
- Load a Word document using the Document.LoadFromFile() method.
- Initialize an instance of the SizeF structure from specified dimensions.
- Iterate through the sections in the document.
- Adjust the page size of each section to the specified dimensions by assigning the SizeF instance to the Section.PageSetup.PageSize property.
- Save the result document using the Document.SaveToFile() method.
- C#
- VB.NET
using Spire.Doc;
using System.Drawing;
namespace ChangePageSizeToCustomSize
{
internal class Program
{
static void Main(string[] args)
{
//Initialize an instance of the Document class
Document doc = new Document();
//Load a Word document
doc.LoadFromFile("Input.docx");
//Initialize an instance of the SizeF structure from specified dimensions
SizeF customSize = new SizeF(600, 800);
//Iterate through the sections in the document
foreach (Section section in doc.Sections)
{
//Change the page size of each section to the specified dimensions
section.PageSetup.PageSize = customSize;
}
//Save the result document
doc.SaveToFile("CustomSize.docx", FileFormat.Docx2016);
}
}
}
