我需要在visual studio中解析c代码中的json文件。但是当我包含json-c头时，我得到了错误。我该如何解决这些问题呢？

#include<ntddk.h>
#include<wdf.h>
#include<fwpmk.h>
#include<fwpsk.h>
#define INITGUID
#include<guiddef.h>
#include<fwpmu.h>

#undef _CRT_STRINGIZE
#undef _CRT_WIDE
#undef __CRTDECL
#include<json-c/json.h>
#include<json-c/json_object.h>

The errors are:

Severity    Code    Description Project File    Line    Suppression State

刚刚看了一下github页面，上面写着（强调我的）：
要使用json-c，您可以包含json. h、或最好包含，后者是以下更具体的头文件之一：

json_object.h - Core types and methods.
json_tokener.h - Methods for parsing and serializing json-c object trees.
json_pointer.h - JSON Pointer (RFC 6901) implementation for retrieving objects from a json-c object tree.
json_object_iterator.h - Methods for iterating over single json_object instances. (See also json_object_object_foreach() in json_object.h)
json_visit.h - Methods for walking a tree of json-c objects.
json_util.h - Miscellaneous utility functions.

所以，看起来你包含了json. h * 和 * json_object. h。这就解释了宏的重定义。试着去掉#include<json-c/json.h>。
