C# 代码卡住形式，我错过了一个中断的循环吗？

Question

private int coreCountNum()
    {
        int coreCount = 0;
        foreach (var item in new System.Management.ManagementObjectSearcher("Select NumberOfCores from Win32_Processor").Get())
        {
            coreCount += int.Parse(item["NumberOfCores"].ToString());    
        }
        return coreCount;
    }
private void button1_Click(object sender, EventArgs e)
    {
        coreCount.Text = Convert.ToString(coreCountNum());
    }

这是我的一些代码，我认为可能有错误，如果有人能发现，请告诉我。单击该按钮时，它会在标签上显示核心计数，但随后会卡住，谢谢。

尝试显式处理 ManagementObjectSearcher

private int coreCountNum()
{
    using(var searcher = new System.Management.ManagementObjectSearcher("Select NumberOfCores from Win32_Processor"))
    {
        int coreCount = 0;
        foreach (var item in searcher.Get())
        {
            coreCount += int.Parse(item["NumberOfCores"].ToString());    
        }
        return coreCount;
    }
}
