Finding specific text or phrases in a long Word document can be a bit of a hassle. Fortunately, MS Word provides the "Find" function to locate specific content in a document quickly. You can also highlight the found content with a background color to ensure that they won't be overlooked by the readers. This article will demonstrate how to programmatically find and highlight text in a Word document using Spire.Doc for .NET.
Install Spire.Doc for .NET
To begin with, you need to add the DLL files included in the Spire.Doc for .NET package as references in your .NET project. The DLLs files can be either downloaded from this link or installed via NuGet.
PM> Install-Package Spire.Doc
Find and Highlight Text in a Word Document
The detailed steps are as follows.
- Create a Document instance
- Load a sample Word document using Document.LoadFromFile() method.
- Find all matching text in the document using Document.FindAllString(string matchString, bool caseSensitive, bool wholeWord) method.
- Loop through all matching text in the document.
- Get the text range of a specific matching text using TextSelection.GetAsOneRange() method, and then set its highlight color using TextRange.CharacterFormat.HighlightColor property.
- Save the result file using Document.SaveToFile() method.
- C#
- VB.NET
using System.Drawing;
using Spire.Doc;
using Spire.Doc.Documents;
namespace FindHighlight
{
class Program
{
static void Main(string[] args)
{
//Create a Document instance
Document document = new Document();
//Load a sample Word document
document.LoadFromFile("input.docx");
//Find all matching text in the document
TextSelection[] text = document.FindAllString("transcendentalism", false, true);
//Loop through all matching text and set highlight color for them
foreach (TextSelection seletion in text)
{
seletion.GetAsOneRange().CharacterFormat.HighlightColor = Color.Yellow;
}
//Save the result file
document.SaveToFile("FindHighlight.docx", FileFormat.Docx);
}
}
}

Word Heading can be taken as title of each part in Word document. This guide demonstrates solution to manage these Word headings and form them as a catalogue in C# and VB.NET.
In Word document, users can set some contents, for example, phrases of summary of the following paragraphs, as headings. These Word headings can be displayed in the first page of whole document and form as catalogue after arrangement so that readers can get outline of whole document. Solution in this guide presents how to manage Word headings with numbered style in a new created document in C# and VB.NET via Spire.Doc for .NET and screenshot below shows results of managing Word headings.
Heading is one of kind of styles for paragraphs and Spire.Doc for .NET provides several BuiltinStyle types for paragraphs. In this example, three BuiltinStyle types will be applied: Heading1, Heading2 and Heading3. Following, details will be presented step by step.
Firstly, initialize a Document instance and add section, paragraph for this instance. Secondly, invoke AppendText method with parameter string text and ApplyStyle(BuiltinStyle.Heading1) method of Paragraph class to add text and set heading style for new added paragraph. Then, invoke ListFromat.ApplyNumberedStyle() method of Paragraph class to set number list for it. Thirdly, add new paragraph and set Heading2 style for it as the previous step. Initialize a ListStyle instance for document with Numbered ListType. Then, initialize a ListLevel instance from ListStyle and set UsePrevLevelPattern and NumberPrefix properties for this instance. After that, invoke ListStyleCollection.Add(ListStyle) method of Document class and ListFormat.ApplyStyle method of Paragraph class with parameter string styleName to add ListStyle for Heading2. Fourthly, add a new paragraph and set BuiltinStyle as Heading3 and apply ListStyle for this paragraph as the previous step. Finally, invoke SaveToFile method of Document class with parameter string fileName and FileFormat to save this document. Refer the code:
using Spire.Doc;
using Spire.Doc.Documents;
namespace WordHeading
{
class Heading
{
static void Main(string[] args)
{
//Create Document
Document document = new Document();
Section section = document.AddSection();
Paragraph paragraph = section.Paragraphs.Count > 0 ? section.Paragraphs[0] : section.AddParagraph();
//Add Heading 1
paragraph = section.AddParagraph();
paragraph.AppendText(BuiltinStyle.Heading1.ToString());
paragraph.ApplyStyle(BuiltinStyle.Heading1);
paragraph.ListFormat.ApplyNumberedStyle();
//Add Heading 2
paragraph = section.AddParagraph();
paragraph.AppendText(BuiltinStyle.Heading2.ToString());
paragraph.ApplyStyle(BuiltinStyle.Heading2);
//List Style for Headings 2
ListStyle listSty2 = document.Styles.Add(ListType.Numbered, "MyStyle2");
foreach (ListLevel listLev in listSty2.ListRef.Levels)
{
listLev.UsePrevLevelPattern = true;
listLev.NumberPrefix = "1.";
}
paragraph.ListFormat.ApplyStyle(listSty2.Name);
//Add List Style 3
ListStyle listSty3 = document.Styles.Add(ListType.Numbered, "MyStyle3");
foreach (ListLevel listLev in listSty3.ListRef.Levels)
{
listLev.UsePrevLevelPattern = true;
listLev.NumberPrefix = "1.1.";
}
//Add Heading 3
for (int i = 0; i < 4; i++)
{
paragraph = section.AddParagraph();
//Append Text
paragraph.AppendText(BuiltinStyle.Heading3.ToString());
//Apply List Style 3 for Heading 3
paragraph.ApplyStyle(BuiltinStyle.Heading3);
paragraph.ListFormat.ApplyStyle(listSty3.Name);
}
//Save and Launch
document.SaveToFile("Word Headings.docx", FileFormat.Docx);
}
}
}
