最近從unity5.1.3升級到5.3.4的時候，發現有個問題：

system.io.file‘ does not contain a definition for readalltext on webplayer in Unity, 上網查資料，有個老外說This is due to the sandboxing security of the webplayer, which has certain limitations imposed to prevent malicious code being executed by a unity application via the browser.

Unity‘s docs include a page explaining this:

http://docs.unity3d.com/Manual/SecuritySandbox.html

Which includes the following brief description of the limitations:

• Restrictions on accessing data on a domain other than the one hosting your .unity3d file.
• Some limitation on the usage of the Sockets.
• Disallowing invocation of any method we deemed off limits. (things
  like File.Delete, etc).
• Disallowing the usage of System.Reflection.* to call private/internal methods in classes you did not write yourself.

In short, you cannot access the filesystem directly using the System.IO namespace. This has been disabled intentionally by Unity.

The best practice is to use the PlayerPrefs, or to load/save data via a remote web service. There‘s a discussion on the topic here:

既需要轉換platform，但是發現按鈕是灰色的，點擊右邊的Module Manager按鈕也不管用，

只好重新開啟安裝助手，勾選Android Build Support安裝即可。ios也一樣。
