CString::Find [アーティクル] 2008/03/20 This method searches this string for the first match of a substring. The method is overloaded to accept both single characters (similar to thestrchrrun-time function) and strings (similar tostrstr). ...
int Find(LPCTSTR lpszSub); 复制代码 ReverseFind: This method is used to find the last occurrence of a substring within the CString object. It takes the substring to search as a parameter and returns the zero-based index of the last occurrence if found, or -1 if not found. The method s...
1. CString::Find 的基本用法 CString::Find 方法用于在字符串中查找子字符串或字符的位置。它返回找到的位置的索引(从0开始计数),如果未找到则返回-1。 cpp int Find( TCHAR ch, int nStart = 0 ) const; int Find( LPCTSTR lpszSubString, int nStart = 0 ) const; ch:要查找的单个字符。 lpszSub...
cout << "Substring not found" << endl; } return 0; } ``` 在上述代码中,我们定义了一个字符串str和一个子字符串substr,并使用cstringfind函数查找子字符串在原字符串中的位置。如果找到了子字符串,则输出其在原字符串中的位置;否则输出“Substring not found”。 需要注意的是,Cstringfind函数是区分大小...
一般来说,在处理字符串的时候通常会用到如下一些函数/方法:length、substring、find、charAt、 toLowerCase、toUpperCase、trim、equalsIgnoreCase、startsWith、endsWith、 parseInt、toString、split等。 如果使用STL中的std::string,它已经提供了如下一些比较有用的方法: ...
size_tlastSlashPos=path.find_last_of("/"); if(lastSlashPos!=std::string::npos){ // 截取子串 std::string subString=path.substr(0,lastSlashPos); // 输出结果 std::cout<<"截取结果:"<<subString<<std::endl; }else{ std::cout<<"未找到斜杠"<<std::endl; ...
呵呵：MSDN:的秒速如图The zero-based index of the first character in this CString object that matches the requested substring or characters; -1 if the substring or character is not found.也就是基于下标为0的的查找；第一个是查找的字符，第二个是查找的开始位置；返回的是字符串的位置，...
int Find( TCHAR ch**, int** nStart ) const;int Find( LPCTSTR pstr**, int** nStart ) const;Return ValueThe zero-based index of the first character in this CString object that matches the requested substring or characters; -1 if the substring or character is not found....
//返回值：提取出的字符串个数 int ExtString(CString str, CStringArray &strArray){ CString strTemp;int nCount = 0;strArray.RemoveAll();while(str.Find(_T("，")) != -1)//查找字符串中是否有“，”出现 { strTemp = str.Left(str.Find(_T("，")));//提取字符串 str = str....
