编译器可以使用 /Wv 编译器选项抑制在指定的版本之后引入的警告。 当引入新的工具集版本并希望暂时抑制新警告时，此选项对于管理生成过程很有用。 此选项仅抑制警告，而不抑制新的错误消息。 不要永久抑制所有新警告！ 建议始终在最高的常规警告级别上 /W4 进行编译，并尽快删除生成中的 /Wv 选项。 以下版本的编译器引入了新的警告： 产品 编译器版本号 Visual Studio 2002 13.00.9466 Visual Studio 2003 13.10.3077 Visual Studio 2005 14.00.50727.762 Visual Studio 2008 15.00.21022.08 Visual Studio 2010 16.00.40219.01 Visual Studio 2012 17.00.51106.1 Visual Studio 2013
