BOOL AFXAPI AfxExtractSubString ( CString& rString, LPCTSTR lpszFullString, int iSubString, TCHAR chSep = '\n');app
rString 對CString將獲得一個單獨的子字符串的對象。函數
lpszFullString 字符串包含字符串的全文提取自。.net
iSubString 提取的子字符串的從零開始的索引從lpszFullString。code
chSep 使用的分隔符分隔子字符串,默認的是'\n'。htm
TRUE ,若是函數成功提取了該子字符串中提供的索引;不然, FALSE。對象
// 使用AfxExtractSubString分割字符串 void CSplitString::SplitString1() { std::vector<long> arrPic; CString strContent = _T("1,2,3,4,5"); CString strTemp; int iPos = 0; while (AfxExtractSubString(strTemp, strContent, iPos, ',')) { iPos++; arrPic.push_back(_wtol(strTemp)); } }
// 利用STL本身實現字符串分割 void CSplitString::SplitString2() { const std::string s("1,2,3,4,5;6;7;8;9"); std::vector<std::string> v; const std::string c(",;");//多個分隔符 std::string::size_type pos1, pos2; pos2 = s.find_first_of(c); pos1 = 0; while (std::string::npos != pos2) { v.push_back(s.substr(pos1, pos2 - pos1)); pos1 = pos2 + 1; pos2 = s.find_first_of(c, pos1); } if (pos1 != s.length()) v.push_back(s.substr(pos1)); }
// 使用C的_tcstok分割字符串 void CSplitString::SplitString3() { CString str = _T("a,b*c,d"); TCHAR seps[] = _T(",*");//可按多個字符來分割 TCHAR *next_token1 = NULL; TCHAR* token = _tcstok_s((LPTSTR)(LPCTSTR)str, seps,&next_token1); while (token != NULL) { TRACE("\r\nstr=%s token=%s\r\n", str, token); token = _tcstok_s(NULL, seps, &next_token1); } }
