What is the purpose of the EventLog class in C#?

1. To capture log events

2. To store user preferences

3. To manage file access

4. To handle network requests

The correct answer is: To capture log events

The EventLog class in C# is specifically designed to interact with the event logs on a Windows operating system. Its primary purpose is to capture log events, which can include information about application or system functionality, such as errors, warnings, and informational messages. By using this class, developers can write entries to the system event log, which helps in monitoring and troubleshooting applications by providing a historical record of events. This class allows for various operations such as creating, deleting, and clearing event logs, as well as reading log entries. This capability is essential for applications that need to provide diagnostic information for support or maintenance tasks. The other options, while they may represent valid tasks in application development, do not relate to the EventLog class's core functionality. Storing user preferences is typically handled using settings or configuration files, managing file access involves file I/O classes, and handling network requests is performed through networking classes and libraries. Thus, capturing log events is the distinct function of the EventLog class in C#.
