首先添加对 System.Management的引用
然后代码入下：
ConnectionOptions op = new ConnectionOptions ( ) ; 
   op.Username ="wgscd";’或者你的帐号（注意要有管理员的权限）
   op.Password = "wgscd" ; ’你的密码
   ManagementScope scope = new ManagementScope( "////" + "106.54.20.1" + "//root//wgscd", 
op ) ; 
   try
   {
    scope.Connect ( ) ;
    System.Management.ObjectQuery oq = new System.Management.ObjectQuery ( "SELECT * FROM 

Win32_OperatingSystem" ) ; 
    ManagementObjectSearcher query1 = new ManagementObjectSearcher ( scope , oq ) ; 
    //得到WMI控制 
    ManagementObjectCollection queryCollection1 = query1.Get ( ) ; 

    foreach ( ManagementObject mobj in queryCollection1 ) 
    { 
     string [ ] str= { "" } ;  
     mobj.InvokeMethod ( "Reboot" , str ) ; 
    } 
   }
   catch
   {
   
   }
