This article mainly introduces in detail how C# inserts a new paragraph and hides paragraphs into a word document. , has certain reference value, interested friends can refer to

When editing a Word document, we sometimes suddenly want to add a new piece of content; and when letting others browse the Word document, some information we Don't want others to see it. So how to use C# programming to cleverly insert or hide paragraphs? This article will share with you a good way to insert new paragraphs and hide paragraphs into Word documents.

The Free Spire.Doc for .NET component is used here, which allows developers to easily and flexibly operate Word documents.

Steps to insert a new paragraph into a Word document

##Step 1:Create a new document and Load an existing document


Document document = new Document();
document.LoadFromFile(@"C:\Users\Administrator\Desktop\向日葵.docx", FileFormat.Docx);

Step 2:Insert a new paragraph and format the font


Paragraph paraInserted = document.Sections[0].AddParagraph();
TextRange textRange1 = paraInserted.AppendText("向日葵的花语是——太阳、光辉、高傲、忠诚、爱慕、沉默的爱。向日葵又叫望日莲,一个很美的名字");
textRange1.CharacterFormat.TextColor = Color.Blue;
textRange1.CharacterFormat.FontSize = 15;
textRange1.CharacterFormat.UnderlineStyle = UnderlineStyle.Dash;

Step 3:Save the document


document.SaveToFile("result.docx", FileFormat.Docx);

##Steps to hide paragraphs
When operating a Word document, we can hide the selected text by clicking the Font dialog box in Microsoft Word. Please take a look at the screenshot below to see how Microsoft hides text:

However, Free Spire.Doc for .NET can hide specified text by setting the CharacterFormat.Hidden property. text or the entire paragraph, the detailed steps will be introduced below:

Step 1:

Create a new document and load the existing document

Document doc = new Document();
doc.LoadFromFile(@"C:\Users\Administrator\Desktop\雏菊.docx", FileFormat.Docx);

Step 2:

Get the first section and the last section of the Word document

Section sec = doc.Sections[0];
Paragraph para = sec.Paragraphs[sec.Paragraphs.Count - 1];

Step 3:

Call the for loop statement to get all TextRange of the last paragraph and set the property of CharacterFormat.Hidden to true

for (int i = 0; i < para.ChildObjects.Count;i++)
  {
  (para.ChildObjects[i] as TextRange).CharacterFormat.Hidden = true;

  }

Step 4:

Save the document

doc.SaveToFile("result1.docx", FileFormat.Docx);

C# is a programming language released by Microsoft in 2000, aiming to combine the power of C and the simplicity of Java. 1.C# is a type-safe, object-oriented programming language that supports encapsulation, inheritance and polymorphism. 2. The compilation process of C# converts the code into an intermediate language (IL), and then compiles it into machine code execution in the .NET runtime environment (CLR). 3. The basic usage of C# includes variable declarations, control flows and function definitions, while advanced usages cover asynchronous programming, LINQ and delegates, etc. 4. Common errors include type mismatch and null reference exceptions, which can be debugged through debugger, exception handling and logging. 5. Performance optimization suggestions include the use of LINQ, asynchronous programming, and improving code readability.

mPDF

mPDF

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
