以編程方式檢查是否安裝了Windows消息傳遞？

Question

有一種簡單的方法來檢測郵件組件是否安裝和服務是用C＃在Windows上運行？

Answer 1

檢查服務，其狀態的存在，可以通過執行WMI查詢來完成：

// Setup the query 
ManagementObjectSearcher searcher = new ManagementObjectSearcher("root\\CIMV2", 
        "SELECT * FROM Win32_Service WHERE Name = 'Blah'"); 

// Execute the query and enumerate the objects 
foreach (ManagementObject queryObj in searcher.Get()) 
{ 
    // examine the query results to find the info you need. For example: 
    string name = (string)queryObj["Name"]; 
    bool started = (bool)queryObj["Started"]; 
    string status = (string)queryObj["Status"]; 
}
