VC 中如何从字符串中分离文件名与路径+路径操作

#include "stdafx.h"
#include "PathStringManager.h"

CPathStringOper::CPathStringOper(void)
{
}

CPathStringOper::~CPathStringOper(void)
{
}

CPathStringOper::GetFolderPathFromFullPath(LPCTSTR lpszFullPath)
{
 // 获取文件路径：
 // 注意不是“/”以结尾,因为使用过程中加上一个“/”容易，减去一个不容易
 CString m_strOriFileName(lpszFullPath);

 CString strPath;
    int n=m_strOriFileName.ReverseFind('//')+1;
    strPath=m_strOriFileName.Left(n);
 return strPath;
}

CPathStringOper::GetFileFullNameFromFullPath(LPCTSTR lpszFullPath)
{
 // 获取文件名：
 CString m_strOriFileName(lpszFullPath);
   
    CString strPath;
    int n=m_strOriFileName.GetLength()-m_strOriFileName.ReverseFind('//')-1;
    strPath=m_strOriFileName.Right(n);

 return strPath;
}

CPathStringOper::GetFileExtNameFromFullPath(LPCTSTR lpszFullPath)
{
    // 同理，获取文件后缀名则为：
    CString m_strOriFileName(lpszFullPath);
 
 CString strFileType;
    int n=m_strOriFileName.GetLength()-m_strOriFileName.ReverseFind('.')-1;
    strFileType=m_strOriFileName.Right(n);

 return strFileType;
}

>>> 后来发现Windows 本身就能,就提供API实现

不过  GetFolderPathFromFullPath(LPCTSTR lpszFullPath),GetFileExtNameFromFullPath(LPCTSTR lpszFullPath) API没有
