How to Specify Custom Date Formats for DateTime Serialization in Json.Net without Global Settings?

Json.Net custom DateTime serialized date format
Question:
When using Json.Net serialization in ASP.NET Web API, how to specify a custom date format while avoiding modifying global settings to meet the needs of a specific application?
Answer:
The recommended approach is to use a custom JsonConverter for selective formatting. Json.Net provides an IsoDateTimeConverter that allows custom formatting. Since the format cannot be set directly through the JsonConverter property, you can create a subclass and specify the desired format in its constructor. A custom converter can then be applied to a specific property using the JsonConverter property:
class CustomDateTimeConverter : IsoDateTimeConverter
{
public CustomDateTimeConverter()
{
base.DateTimeFormat = "yyyy'-'MM'-'dd";
}
}
class ReturnObjectA
{
[JsonConverter(typeof(CustomDateTimeConverter))]
public DateTime ReturnDate { get; set; }
}
If you do not need the time format, you can directly apply the default date format of IsoDateTimeConverter:
[JsonConverter(typeof(IsoDateTimeConverter))]
public DateTime ReturnDate { get; set; }The above is the detailed content of How to Specify Custom Date Formats for DateTime Serialization in Json.Net without Global Settings?. For more information, please follow other related articles on the PHP Chinese website!

C Polymorphism : is function overloading a kind of polymorphism?
Jun 20, 2025 am 12:05 AM
Yes, function overloading is a polymorphic form in C, specifically compile-time polymorphism. 1. Function overload allows multiple functions with the same name but different parameter lists. 2. The compiler decides which function to call at compile time based on the provided parameters. 3. Unlike runtime polymorphism, function overloading has no extra overhead at runtime, and is simple to implement but less flexible.
What Are the Different Kinds of Polymorphism in C ? Explained
Jun 20, 2025 am 12:08 AM
C has two main polymorphic types: compile-time polymorphism and run-time polymorphism. 1. Compilation-time polymorphism is implemented through function overloading and templates, providing high efficiency but may lead to code bloating. 2. Runtime polymorphism is implemented through virtual functions and inheritance, providing flexibility but performance overhead.
C : Is Polymorphism really useful?
Jun 20, 2025 am 12:01 AM
Yes, polymorphisms in C are very useful. 1) It provides flexibility to allow easy addition of new types; 2) promotes code reuse and reduces duplication; 3) simplifies maintenance, making the code easier to expand and adapt to changes. Despite performance and memory management challenges, its advantages are particularly significant in complex systems.

Polymorphism in C : A Comprehensive Guide with Examples
Jun 21, 2025 am 12:11 AM
Polymorphisms in C are divided into runtime polymorphisms and compile-time polymorphisms. 1. Runtime polymorphism is implemented through virtual functions, allowing the correct method to be called dynamically at runtime. 2. Compilation-time polymorphism is implemented through function overloading and templates, providing higher performance and flexibility.
C tutorial for people who know Python
Jul 01, 2025 am 01:11 AM
People who study Python transfer to C The most direct confusion is: Why can't you write like Python? Because C, although the syntax is more complex, provides underlying control capabilities and performance advantages. 1. In terms of syntax structure, C uses curly braces {} instead of indentation to organize code blocks, and variable types must be explicitly declared; 2. In terms of type system and memory management, C does not have an automatic garbage collection mechanism, and needs to manually manage memory and pay attention to releasing resources. RAII technology can assist resource management; 3. In functions and class definitions, C needs to explicitly access modifiers, constructors and destructors, and supports advanced functions such as operator overloading; 4. In terms of standard libraries, STL provides powerful containers and algorithms, but needs to adapt to generic programming ideas; 5
