C# XML Deserialization: A Complete Guide
Deserializing XML data into objects is a critical step in accessing and processing structured information in a variety of applications. This article will dive into how to build classes for successful XML deserialization.
Build classes for deserialization
Consider the following XML example:
<steplist><step><name>Name1</name><desc>Desc1</desc></step><step><name>Name2</name><desc>Desc2</desc></step></steplist>
To deserialize this XML, define the following class:
[XmlRoot("StepList")] public class StepList { [XmlElement("Step")] public List<Step> Steps { get; set; } } public class Step { [XmlElement("Name")] public string Name { get; set; } [XmlElement("Desc")] public string Desc { get; set; } }
Example usage
The following test code demonstrates the deserialization process:
string testData = @"<StepList> <Step> <Name>Name1</Name> <Desc>Desc1</Desc> </Step> <Step> <Name>Name2</Name> <Desc>Desc2</Desc> </Step> </StepList>"; XmlSerializer serializer = new XmlSerializer(typeof(StepList)); using (TextReader reader = new StringReader(testData)) { StepList result = (StepList)serializer.Deserialize(reader); }
Load from file
If the XML data is stored in a file, it can be deserialized using FileStream:
using (FileStream fileStream = new FileStream("<你的文件路径>", FileMode.Open)) { StepList result = (StepList)serializer.Deserialize(fileStream); }
By following these guidelines and using the provided examples, you can efficiently deserialize XML data and process it as objects in your application.

C is still important in modern programming because of its efficient, flexible and powerful nature. 1)C supports object-oriented programming, suitable for system programming, game development and embedded systems. 2) Polymorphism is the highlight of C, allowing the call to derived class methods through base class pointers or references to enhance the flexibility and scalability of the code.

The performance differences between C# and C are mainly reflected in execution speed and resource management: 1) C usually performs better in numerical calculations and string operations because it is closer to hardware and has no additional overhead such as garbage collection; 2) C# is more concise in multi-threaded programming, but its performance is slightly inferior to C; 3) Which language to choose should be determined based on project requirements and team technology stack.

C is widely used and important in the modern world. 1) In game development, C is widely used for its high performance and polymorphism, such as UnrealEngine and Unity. 2) In financial trading systems, C's low latency and high throughput make it the first choice, suitable for high-frequency trading and real-time data analysis.

There are four commonly used XML libraries in C: TinyXML-2, PugiXML, Xerces-C, and RapidXML. 1.TinyXML-2 is suitable for environments with limited resources, lightweight but limited functions. 2. PugiXML is fast and supports XPath query, suitable for complex XML structures. 3.Xerces-C is powerful, supports DOM and SAX resolution, and is suitable for complex processing. 4. RapidXML focuses on performance and parses extremely fast, but does not support XPath queries.

C interacts with XML through third-party libraries (such as TinyXML, Pugixml, Xerces-C). 1) Use the library to parse XML files and convert them into C-processable data structures. 2) When generating XML, convert the C data structure to XML format. 3) In practical applications, XML is often used for configuration files and data exchange to improve development efficiency.

The main differences between C# and C are syntax, performance and application scenarios. 1) The C# syntax is more concise, supports garbage collection, and is suitable for .NET framework development. 2) C has higher performance and requires manual memory management, which is often used in system programming and game development.

The history and evolution of C# and C are unique, and the future prospects are also different. 1.C was invented by BjarneStroustrup in 1983 to introduce object-oriented programming into the C language. Its evolution process includes multiple standardizations, such as C 11 introducing auto keywords and lambda expressions, C 20 introducing concepts and coroutines, and will focus on performance and system-level programming in the future. 2.C# was released by Microsoft in 2000. Combining the advantages of C and Java, its evolution focuses on simplicity and productivity. For example, C#2.0 introduced generics and C#5.0 introduced asynchronous programming, which will focus on developers' productivity and cloud computing in the future.

DVWA
Damn Vulnerable Web App (DVWA) is a PHP/MySQL web application that is very vulnerable. Its main goals are to be an aid for security professionals to test their skills and tools in a legal environment, to help web developers better understand the process of securing web applications, and to help teachers/students teach/learn in a classroom environment Web application security. The goal of DVWA is to practice some of the most common web vulnerabilities through a simple and straightforward interface, with varying degrees of difficulty. Please note that this software

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),
