Spire.Doc for .NET (337)
Children categories
Line numbers is used to display the number of lines counted automatically by Word next to each line of text. It's very useful when we need to refer to specific lines in a document such as contract or legal papers. Line numbers function in word allows us to set the start value, the number interval, the distance from text and the numbering mode of line numbers. Using Spire.Doc, we could achieve all of features mentioned above. This article is going to introduce how to add line numbers in C# using Spire.Doc.
Note: Before start, please download the latest version of Spire.Doc and add Spire.Doc .dll in the bin folder as the reference of visual studio.
Step 1: Load the sample document which only has text.
Document document = new Document();
document.LoadFromFile("T.docx");
Step 2: Set the start value of the line numbers.
document.Sections[0].PageSetup.LineNumberingStartValue = 1;
Step 3: Set the interval between displayed numbers.
document.Sections[0].PageSetup.LineNumberingStep = 6;
Step 4: Set the distance between line numbers and text.
document.Sections[0].PageSetup.LineNumberingDistanceFromText = 40f;
Step 5: Set the numbering mode of line numbers. Here we have four choices: None, Continuous, RestartPage and RestartSection.
document.Sections[0].PageSetup.LineNumberingRestartMode = LineNumberingRestartMode.Continuous;
Step 6: Save the document and launch to see effects.
document.SaveToFile("result.docx",FileFormat.Docx2013);
System.Diagnostics.Process.Start("result.docx");
Effects:
Single Page:
Continuous Page:

New method get alias, tag and id of content controls in a Word document in C#
2015-06-05 03:59:58 Written by KoohjiContent controls provide a way for you to design documents. When you add a content control to a document, the control is identified by a border, a title, and temporary text that can provide instructions to the user, and can prevent users from editing or deleting protected sections of a document.
Bind parts of a document or template to data. You can bind content controls to database fields, managed objects in the .NET Framework, XML elements that are stored in the document, and other data sources.
This article illustrates how to get all controls and their properties including alias, id and tag via Spire.Doc with new method and replace the Barcode with another image.
Refer this article to check old method: Get alias, tag and id of content controls in a Word document in C#
The following is test file new.docx.
Here are the steps:
Step 1: Create a new Word document and load the test file.
Document doc = new Document(@"new.docx");
Step 2: Create a list StructureDocument to store tags. Here, each content control will be identified by tag.
public class StructureTags
{
List m_structureDocumnt;
public List StructureDocument
{
get
{
if (m_structureDocumnt == null)
m_structureDocumnt = new List();
return m_structureDocumnt;
}
}
}
Step 3: Use foreach sentence to get all tags in the Word document.
foreach (Section section in doc.Sections)
{
foreach (Body body in section.ChildObjects)
{
ModifyBody(body);
}
}
Step 4: Show the properties of all controls.
List tagInlines = structureTags.StructureDocument;
Console.WriteLine("Part1");
for (int i = 0; i < tagInlines.Count; i++)
{
string alias = tagInlines[i].SDTProperties.Alias; // Can be null or empty
decimal id = tagInlines[i].SDTProperties.Id;
string tag = tagInlines[i].SDTProperties.Tag;
string STDType = tagInlines[i].SDTProperties.SDTType.ToString();
Console.WriteLine("{0,20},{1,15},{2, 10} - {3}", alias, id, STDType, tag);
Console.ReadKey();
}
Step 5: Replace image inside of Picture Content Control.
doc.SaveToFile("replace1.docx", FileFormat.Docx2013);
System.Diagnostics.Process.Start("replace1.docx");

Headers and footers are widely used to show addition information such as chapter name, page numbers to keep the document organized. By default, MS Word sets the same headers and footers on each page, but sometimes we need to create different headers or footers for odd and even pages. This article is going to introduce the method to set different odd and even header/footer using Spire.Doc in C#.
Note: Before Start, please download the latest version of Spire.Doc and add Spire.Doc .dll in the bin folder as the reference of Visual Studio.
Step 1: Create a new document and load from file.
Document document = new Document();
document.LoadFromFile("T1.docx");
Step 2: Add a section and set the property true.
Section section = document.Sections[0]; section.PageSetup.DifferentOddAndEvenPagesHeaderFooter = true;
Step 3: Create odd and even footer, odd and even header, and set their format.
//add EvenFooter
Paragraph P1 = section.HeadersFooters.EvenFooter.AddParagraph();
TextRange EF = P1.AppendText("Even Footer Demo from E-iceblue Using Spire.Doc");
EF.CharacterFormat.FontName = "Calibri";
EF.CharacterFormat.FontSize = 20;
EF.CharacterFormat.TextColor = Color.Green;
EF.CharacterFormat.Bold = true;
P1.Format.HorizontalAlignment = HorizontalAlignment.Center;
//add OddFooter
Paragraph P2 = section.HeadersFooters.OddFooter.AddParagraph();
TextRange OF = P2.AppendText("Odd Footer Demo");
P2.Format.HorizontalAlignment = HorizontalAlignment.Center;
OF.CharacterFormat.FontName = "Calibri";
OF.CharacterFormat.FontSize = 20;
OF.CharacterFormat.Bold = true;
OF.CharacterFormat.TextColor = Color.Blue;
//add OddHeader
Paragraph P3 = section.HeadersFooters.OddHeader.AddParagraph();
TextRange OH = P3.AppendText("Odd Header Demo");
P3.Format.HorizontalAlignment = HorizontalAlignment.Center;
OH.CharacterFormat.FontName = "Calibri";
OH.CharacterFormat.FontSize = 20;
OH.CharacterFormat.Bold = true;
OH.CharacterFormat.TextColor = Color.Blue;
//add EvenHeader
Paragraph P4 = section.HeadersFooters.EvenHeader.AddParagraph();
TextRange EH = P4.AppendText("Even Header Demo from E-iceblue Using Spire.Doc");
P4.Format.HorizontalAlignment = HorizontalAlignment.Center;
EH.CharacterFormat.FontName = "Calibri";
EH.CharacterFormat.FontSize = 20;
EH.CharacterFormat.Bold = true;
EH.CharacterFormat.TextColor = Color.Green;
Step 4: Save the document and launch to see effects.
document.SaveToFile("R.docx", FileFormat.Docx2010);
System.Diagnostics.Process.Start("R.docx");
