C＃代碼是凍結窗體，我錯過了一個循環？

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()); 
    } 

這是我的一些代碼，我認爲可能有一個錯誤，如果任何人都可以發現一個，請讓我知道。點擊按鈕後，它會在標籤上顯示核心數量，但會凍結，謝謝。

嘗試處置ManagementObjectSearcher明確

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; 
    } 
}
