C＃代码是冻结窗体，我错过了一个循环？

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，我认为可能有一个错误，如果任何人都可以发现一个，请让我知道。点击按钮后，它会在标签上显示核心数量，但会冻结，谢谢。

尝试处置ManagementObjectSearcher明确

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; 
    } 
}
