Ignore JsonProperty(PropertyName = "someName") property during JSON serialization
Json.Net provides the JsonProperty property to customize the serialization process, allowing developers to specify property names during serialization. However, in some cases (such as when the client is a browser), using shorter property names to reduce load may cause problems with using shorter names in client code.
To work around this issue, you can use a custom contract parser to selectively ignore JsonProperty properties. Here’s how to do it:
public class LongNameContractResolver : DefaultContractResolver { protected override IList<JsonProperty> CreateProperties(Type type, MemberSerialization memberSerialization) { // 使用简短名称获取默认属性 IList<JsonProperty> properties = base.CreateProperties(type, memberSerialization); // 将简短名称替换为原始属性名称 foreach (var property in properties) { property.PropertyName = property.UnderlyingName; } return properties; } }
This parser overrides the CreateProperties method, which first creates a list of properties using shorter names specified by the JsonProperty property. It then loops through each property and replaces the shorter name with the underlying property name.
To use this parser, set it as the contract parser of JsonSerializerSettings:
JsonSerializerSettings settings = new JsonSerializerSettings(); settings.ContractResolver = new LongNameContractResolver();
You can then selectively ignore the JsonProperty property when serializing using custom settings:
// 如果 useLongNames 为 true,则忽略 JsonProperty 属性 if (useLongNames) { settings.ContractResolver = new LongNameContractResolver(); }
This solution allows you to programmatically control when JsonProperty properties are ignored, allowing you to get the desired serialization behavior based on the client type or specific conditions.

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.

The future development trends of C and XML are: 1) C will introduce new features such as modules, concepts and coroutines through the C 20 and C 23 standards to improve programming efficiency and security; 2) XML will continue to occupy an important position in data exchange and configuration files, but will face the challenges of JSON and YAML, and will develop in a more concise and easy-to-parse direction, such as the improvements of XMLSchema1.1 and XPath3.1.

C Reasons for continuous use include its high performance, wide application and evolving characteristics. 1) High-efficiency performance: C performs excellently in system programming and high-performance computing by directly manipulating memory and hardware. 2) Widely used: shine in the fields of game development, embedded systems, etc. 3) Continuous evolution: Since its release in 1983, C has continued to add new features to maintain its competitiveness.

There are significant differences in the learning curves of C# and C and developer experience. 1) The learning curve of C# is relatively flat and is suitable for rapid development and enterprise-level applications. 2) The learning curve of C is steep and is suitable for high-performance and low-level control scenarios.

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 modern C design model uses new features of C 11 and beyond to help build more flexible and efficient software. 1) Use lambda expressions and std::function to simplify observer pattern. 2) Optimize performance through mobile semantics and perfect forwarding. 3) Intelligent pointers ensure type safety and resource management.

C Learners and developers can get resources and support from StackOverflow, Reddit's r/cpp community, Coursera and edX courses, open source projects on GitHub, professional consulting services, and CppCon. 1. StackOverflow provides answers to technical questions; 2. Reddit's r/cpp community shares the latest news; 3. Coursera and edX provide formal C courses; 4. Open source projects on GitHub such as LLVM and Boost improve skills; 5. Professional consulting services such as JetBrains and Perforce provide technical support; 6. CppCon and other conferences help careers

C still has important relevance in modern programming. 1) High performance and direct hardware operation capabilities make it the first choice in the fields of game development, embedded systems and high-performance computing. 2) Rich programming paradigms and modern features such as smart pointers and template programming enhance its flexibility and efficiency. Although the learning curve is steep, its powerful capabilities make it still important in today's programming ecosystem.
