C# replacement for PerformanceCounter

Question

Hi,

I'm wondering if there is a ".net integrated" solution for exact time measurement (like the execution time of a function)? At the moment I'm using the PerformanceCounters from Kernel32.

    [DllImport("Kernel32.dll")]
    private static extern bool QueryPerformanceCounter(
        out long lpPerformanceCount);

    [DllImport("Kernel32.dll")]
    private static extern bool QueryPerformanceFrequency(
        out long lpFrequency);

Answer 1

The Stopwatch is a high resolution framework timer class (that probably wraps that api).

Answer 2

Try

• System.Environment.TickCount
• System.Diagnostics.Stopwatch

Both of these work well for finer resolution and straightforward usage.
