怎么获取不了内存啊！

[davilbobo]

ManagementObjectSearcher mos = new ManagementObjectSearcher();
mos.Query = new SelectQuery("Win32_PhysicalMemory", "", new string[] { "Capacity" });//设置查询条件

ManagementObjectCollection moc = mos.Get();
ManagementObjectCollection.ManagementObjectEnumerator em = moc.GetEnumerator();

int capacity = 0;
while (em.MoveNext())
{
ManagementBaseObject baseObj = em.Current;
if (baseObj.Properties["Capacity"].Value != null)
{
try
{
capacity += int.Parse(baseObj.Properties["Capacity"].Value.ToString());
}
catch
{
// MessageBox.Show("有错误发生！\n", "错误信息", MessageBoxButtons.OK, MessageBoxIcon.Error, MessageBoxDefaultButton.Button1);
return 0;
}
}
}
return capacity;
