使用GetPrivateProfileSectionNames从ini文件中读取所有节的名称

问题描述：

从ini文件中读取所有节的名称.

当我使用 GetPrivateProfileSectionNames 时，我得到的只是第一部分的名称.如何获得下一个部分的名称?请帮忙

Hi,
Reading all section names from ini file.

I am getting the first section name alone when i use GetPrivateProfileSectionNames. How can i get the next section name ? Please help

// reading each section from ini file

  LPWSTR pSecNames= new WCHAR[1024];

  int nSectionNum = 0;
  wstring strSecName;

  DWORD retVal = GetPrivateProfileSectionNames(pSecNames,1024,profileFilePath.c_str());

  if (retVal)
  {
    strSecName.assign(pSecNames,retVal);
  }
  delete pSecNames;

  string sectionName = ToString(strSecName.c_str(),CP_UTF8);

答

来自MSDN :

lpszReturnBuffer [out]
A pointer to a buffer that receives the section names associated with the named file. The buffer is filled with one or more null-terminated strings; the last string is followed by a second null character.

因此，如果您的INI文件为:

So, if your INI file is:

[Hello]
a=1
b=2
[World]
c=3
d=4

pSecNames将为"Hello \ 0World \ 0 \ 0"，而retVal将为13.
您需要某种循环才能全部读取它们:

pSecNames will be "Hello\0World\0\0", and retVal will be 13.
You''ll need some kind of loop to read them all:

// This is pseudo-code, I didn't compile it.
std::list<std::wstring> l;
for (wchar_t * p = pSecNames; *p; ++p)
{
    std::wstring ws(p);
    l.push_back(ws);
    p += ws.size();
    ASSERT(0 == *p);
}

希望这会有所帮助，

LPTSTR lpszReturnBuffer;     
lpszReturnBuffer = new TCHAR[MAX];     
char* pNextSection = NULL;        
GetPrivateProfileSectionNames(lpszReturnBuffer,MAX,IniPath);     
pNextSection = lpszReturnBuffer;     
printf("%s\n", pNextSection);           
CString csAllSections;
while (*pNextSection != 0x00)     
{         
    pNextSection = pNextSection + strlen(pNextSection) + 1;         
    if(*pNextSection != 0x00)         
    {             
        csAllSections += pNextSection;
    }     
}

csAllSections将具有所有节的名称.但没有分开.您必须处理这种逻辑

csAllSections will have all sections name. but not separted. You have to handle that logic
