C# FreeMemory和CPUUsage导致内存泄漏和系统内存不足

然后我用定时器和电话

private float FreeMemory
{
    get { return _nFreeMemory; }
    set
    {
        _nFreeMemory = value;
        statusBarPanelMem.Text = _nFreeMemory + " MB prosto";
    }
}

private int CPUUsage
{
    get { return _nCpuUsage; }
    set
    {
        _nCpuUsage = value;
        statusBarPanelCPU.Text = "CPU poraba " + _nCpuUsage + "%";
    }
}

但正因为如此，我得到了内存泄漏和系统内存不足异常。为什么GC不收集这个？

列出的代码不会导致任何内存泄漏

请明确：这是否会在没有其他代码的情况下，在一个空应用程序中重现问题？计时器的运行速度有多快？

private void InitialiseCounterRamNetwork()
{
    _cpuCounter = new PerformanceCounter("Processor", "% Processor Time", "_Total", true);
    _ramCounter = new PerformanceCounter("Memory", "Available MBytes", true);
}

private void timerMemProcNetwork_Tick(object sender, EventArgs e)
{
   FreeMemory = _ramCounter.NextValue();
   CPUUsage = Convert.ToInt32(_cpuCounter.NextValue());
}
