以编程方式检查是否安装了Windows消息传递？

Question

有一种简单的方法来检测邮件组件是否安装和服务是用C＃在Windows上运行？

Answer 1

检查服务，其状态的存在，可以通过执行WMI查询来完成：

// 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"]; 
}
