SysInfoStrings的用法

Question

protected override void OnPaint(PaintEventArgs pea)
{
Graphics grfx = pea.Graphics;
Brush brush = new SolidBrush(ForeColor);
int iCount = SysInfoStrings.Count;
string[] astrLabels = SysInfoStrings.Labels;
string[] astrValues = SysInfoStrings.Values;

    for (int i = 0; i < iCount; i++)
    {
        grfx.DrawString(astrLabels[i], Font, brush,
                                        0, i * cySpace);
        grfx.DrawString(astrValues[i], Font, brush,
                                        cxCol, i * cySpace);
    }
