大家早上好.所以我试图在我们的c项目中禁用警告4996.它似乎包含在命令行中,如下所示,但编译时,仍会弹出C4966警告.我尝试将警告级别更改为3,或使用/ w44996,但都没有工作.有人知道为什么会这样吗？

编辑：描述中的错字.我的意思是警告4996,而不是4966. 4996在命令行为/ wd“4996”
警告：
warning C4996: 'MBCS_Support_Deprecated_In_MFC': MBCS support in MFC is deprecated and may be removed in a future version of MFC.
解决方法
看起来#pragma警告(禁用：4996)将不会禁用MBCS的弃用警告
在afx.h中_declspec(弃用)行之前的#pragma warning(1：4996)
在afx.h中_declspec(弃用)行之前的#pragma warning(1：4996)
由于模糊的原因,您必须使用#define NO_WARN_MBCS_MFC_DEPRECATION才能禁用此选项.
见afx.h第28-33行
#ifndef NO_WARN_MBCS_MFC_DEPRECATION
#ifdef _MBCS
// Warn about MBCS support being deprecated: see http://go.microsoft.com/fwlink/p/?LinkId=279048 for more information.
#pragma warning(push)
#pragma warning(1 : 4996)
inline __declspec(deprecated("MBCS support in MFC is deprecated and may be removed in a future version of MFC.")) void MBCS_Support_Deprecated_In_MFC() { }
