有没有办法禁用 std 标头的 VS 智能感知警告，而无需用垃圾包装每个包含
Is there a way to disable VS intellisense warnings for std headers without wrapping every include with garbage
问：
Visual Studio 的智能感知生成以下警告：

我显然不希望显示来自 std 标头的警告。 我想出了一个非常丑陋的解决方法，包括将每个 std 包含在整个项目中，如下所示：
#include <CodeAnalysis/Warnings.h>
#pragma warning(push)
#pragma warning(disable: ALL_CODE_ANALYSIS_WARNINGS)
#include <vector>
#pragma warning(pop)
这看起来像垃圾，完全没有意义。 有没有一种简单有效的方法可以告诉 intellisense 忽略 std 标头的警告，或者至少使上述内容更漂亮？

您可以尝试关闭“项目属性设置”下的所有警告。
右键单击您的项目 属性-->配置 属性-->C/C++-->常规
将“警告级别”更改为Turn Off All Warnings(/W0)
或者，如果您不想禁用所有警告，而只想禁用这些显示的特定警告，则可以尝试以下操作：
项目属性-->配置属性-->C/C++-->高级-->在禁用特定警告中键入以下内容：
26495;26439;26451;26819
我只找到了这些，这些方法不会让你单独抑制每个文件中的代码。cpp

是的，我知道这一点，不幸的是，关闭标准库标头中发生的所有警告类型是有害的，因为相同的警告也可能发生在我的代码中，我希望^^报告 好吧，我想除了用垃圾包装包含之外别无他法。

确定。禁止显示所有警告不是一个好的选择。因此，您可以禁止显示项目中的相关特定警告。它不会中断其他类型的警告的显示。使用这个会对你有所帮助。让我们知道这是否对您有所帮助。

只是为了明确我的观点：我不想关闭，比如说 26495，因为我确实希望它在我的代码中报告未初始化的成员。尽管如此，当它发生在标准库头文件中时，我并不关心同样的警告（因为我没有编写它们）。因此，我无法通过禁用特定警告来解决我的问题。
