Windows Service Timer Selection Guide
When building a Windows service that needs to perform tasks periodically, System.Timers.Timer and System.Threading.Timer are two viable timer choices. Both can get the job done effectively, but it's critical to understand their differences and potential impacts.
System.Timers.Timer vs. System.Threading.Timer
System.Timers.Timer and System.Threading.Timer use a separate thread to execute callback functions at specified intervals. However, their underlying mechanisms and threading models are different.
System.Timers.Timer
- Compatible with .NET Framework and .NET Core
- Use a dedicated timer thread to handle callbacks
- Provides a simplified and straightforward API
System.Threading.Timer
- Available only in .NET Framework (not available in .NET Core)
- Use the thread pool to execute callbacks
- Provides finer control and customization options (e.g. cancellation, cross-thread synchronization)
Recommended plan
For Windows services that need to perform tasks periodically, these two timers can effectively meet the needs. Which one you choose depends mainly on the platform (.NET Framework or .NET Core) and the specific needs of your service. If cross-thread synchronization or fine control is required, System.Threading.Timer may be a better choice. For simple applications that don't require these advanced features, System.Timers.Timer can provide an adequate solution.
Usage Example
Here is an example of how to use System.Timers.Timer in a Windows service:
using System.Timers;
public class MyWindowsService
{
private Timer _timer;
public MyWindowsService()
{
_timer = new Timer(10000); // 每 10 秒執(zhí)行一次
_timer.Elapsed += Timer_Elapsed;
_timer.Start();
}
private void Timer_Elapsed(object sender, ElapsedEventArgs e)
{
// 定期執(zhí)行的代碼
}
}
Please note that it is critical to avoid using System.Web.UI.Timer or System.Windows.Forms.Timer in Windows services as they introduce unnecessary dependencies and may cause service failure.

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
