# PerformanceCounter

URL: https://docs.wisej.com/docs/controls/other-components/performancecounter

The Wisej.NET `PerformanceCounter` component enables reading predefined or custom performance counters and publishing data to custom counters through Windows Performance Monitor.

info
The `PerformanceCounter` implements `IDisposable` . Always dispose of it either:
- Directly: Call `Dispose()` in a try/catch block
- Indirectly: Use language constructs like `using` (C#) or `Using` (VB)

## Features
