Question

可能重複：
How can I make my application check if Adobe flash player is installed on a PC?

我需要確保用戶具有當該程序啓動Internet Explorer安裝最新版本的Flash播放器，沒有人知道我怎麼能檢查爲了這？

Answer 1

使用WMI：

var query = new ManagementObjectSearcher("SELECT * FROM Win32_Product"); 
var res = from ManagementObject m in query.Get() where m.Properties["Name"].Value.ToString() == "Flash Player"; // I don't know the name of flash player installer 
if (res.Count > 0) { ... } 

Answer 2

另一種方法是檢查SWF文件的文件關聯。這將指向一個標識符，告訴你Flash的版本如「ShockwaveFlash.ShockwaveFlash.10」。例如：

var subKey = Registry.ClassesRoot.OpenSubKey(@"ShockwaveFlash.ShockwaveFlash\CurVer"); 
if (subKey != null) 
{ 
    var value = subKey.GetValue(null) as String; 
    // TODO: parse the number after the last period in the string. 
}
