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);The following is a comparison chart before and after the program is run:
##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:
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);
The following is a comparison chart before and after running the program:

The programming process of C# in .NET includes the following steps: 1) writing C# code, 2) compiling into an intermediate language (IL), and 3) executing by the .NET runtime (CLR). The advantages of C# in .NET are its modern syntax, powerful type system and tight integration with the .NET framework, suitable for various development scenarios from desktop applications to web services.

C# is a modern, object-oriented programming language developed by Microsoft and as part of the .NET framework. 1.C# supports object-oriented programming (OOP), including encapsulation, inheritance and polymorphism. 2. Asynchronous programming in C# is implemented through async and await keywords to improve application responsiveness. 3. Use LINQ to process data collections concisely. 4. Common errors include null reference exceptions and index out-of-range exceptions. Debugging skills include using a debugger and exception handling. 5. Performance optimization includes using StringBuilder and avoiding unnecessary packing and unboxing.

Testing strategies for C#.NET applications include unit testing, integration testing, and end-to-end testing. 1. Unit testing ensures that the minimum unit of the code works independently, using the MSTest, NUnit or xUnit framework. 2. Integrated tests verify the functions of multiple units combined, commonly used simulated data and external services. 3. End-to-end testing simulates the user's complete operation process, and Selenium is usually used for automated testing.

Interview with C# senior developer requires mastering core knowledge such as asynchronous programming, LINQ, and internal working principles of .NET frameworks. 1. Asynchronous programming simplifies operations through async and await to improve application responsiveness. 2.LINQ operates data in SQL style and pay attention to performance. 3. The CLR of the NET framework manages memory, and garbage collection needs to be used with caution.

C#.NET interview questions and answers include basic knowledge, core concepts, and advanced usage. 1) Basic knowledge: C# is an object-oriented language developed by Microsoft and is mainly used in the .NET framework. 2) Core concepts: Delegation and events allow dynamic binding methods, and LINQ provides powerful query functions. 3) Advanced usage: Asynchronous programming improves responsiveness, and expression trees are used for dynamic code construction.

C#.NET is a popular choice for building microservices because of its strong ecosystem and rich support. 1) Create RESTfulAPI using ASP.NETCore to process order creation and query. 2) Use gRPC to achieve efficient communication between microservices, define and implement order services. 3) Simplify deployment and management through Docker containerized microservices.

Security best practices for C# and .NET include input verification, output encoding, exception handling, as well as authentication and authorization. 1) Use regular expressions or built-in methods to verify input to prevent malicious data from entering the system. 2) Output encoding to prevent XSS attacks, use the HttpUtility.HtmlEncode method. 3) Exception handling avoids information leakage, records errors but does not return detailed information to the user. 4) Use ASP.NETIdentity and Claims-based authorization to protect applications from unauthorized access.

The meaning of colon (':') in C language: conditional statement: separating conditional expressions and statement block loop statement: separating initialization, conditional and incremental expression macro definition: separating macro name and macro value single line comment: representing the content from colon to end of line as comment array dimension: specify the dimension of the array
