You have a C# application.
The application requires 500 MB of available memory.
You need to identify whether there is enough available memory when the application starts.
Which class should you use?
A . OutOfmemoryException
B . MemoryStream
C . PerformanceCounter
D . DiagnosticsConfigurationHandler
Answer: C
Explanation:
The counter is the mechanism by which performance data is collected. The registry stores the names of all the counters, each of which is related to a specific area of system functionality. Examples include a processor’s busy time, memory usage, or the number of bytes received over a network connection.
