FileSystemWatcher vs. Polling: Which is the Best Approach for Reliable File Change Detection?
FileSystemWatcher vs. Polling: Which is the Best Approach for Reliable File Change Detection?
FileSystemWatcher and Polling: The Best Way to Reliable File Change Detection
In local or network file system monitoring, developers need to weigh the advantages and disadvantages of FileSystemWatcher and scheduled polling in terms of reliability and performance.
FileSystemWatcher
FileSystemWatcher monitors file system events and triggers events when files are created, deleted, or modified. It is generally considered a more efficient method of file change detection because it does not require continuous polling. However, its reliability can be a concern.
Polling
The polling method periodically checks for file changes at set intervals. It is a simpler method, but requires more resources and may impact performance, especially if polling intervals are frequent. However, it provides a more powerful method of file change detection.
Reliability
FileSystemWatcher is known to occasionally fail in production and test environments, causing file changes to be missed. Therefore, it is generally recommended to use polling as the primary mechanism for file change detection, with FileSystemWatcher as a secondary means.
Performance
Polling can impact performance if the polling interval is set too frequently. FileSystemWatcher, on the other hand, is generally more lightweight, but may not be reliable enough for critical applications.
Recommended method
To get the best of both worlds, developers should consider combining FileSystemWatcher with periodic polling. FileSystemWatcher quickly identifies file changes, while occasional polling acts as a backup to catch any missed events.
Additionally, a "Refresh" option is provided in the user interface, allowing users to manually trigger file change detection if desired, further improving reliability without impacting performance.

C# vs. C : History, Evolution, and Future Prospects
Apr 19, 2025 am 12:07 AM
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 of C and XML: Emerging Trends and Technologies
Apr 10, 2025 am 09:28 AM
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.
The Continued Use of C : Reasons for Its Endurance
Apr 11, 2025 am 12:02 AM
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.
C Multithreading and Concurrency: Mastering Parallel Programming
Apr 08, 2025 am 12:10 AM
C The core concepts of multithreading and concurrent programming include thread creation and management, synchronization and mutual exclusion, conditional variables, thread pooling, asynchronous programming, common errors and debugging techniques, and performance optimization and best practices. 1) Create threads using the std::thread class. The example shows how to create and wait for the thread to complete. 2) Synchronize and mutual exclusion to use std::mutex and std::lock_guard to protect shared resources and avoid data competition. 3) Condition variables realize communication and synchronization between threads through std::condition_variable. 4) The thread pool example shows how to use the ThreadPool class to process tasks in parallel to improve efficiency. 5) Asynchronous programming uses std::as
C# vs. C : Learning Curves and Developer Experience
Apr 18, 2025 am 12:13 AM
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 and XML: Exploring the Relationship and Support
Apr 21, 2025 am 12:02 AM
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.
