CString::Mid参数 编辑 语音 nFirst 此CString对象中的要被提取的子串的第一个字符的从零开始的索引。nCount 要从此CString对象中提取的字符数。如果没有提供这个参数,则字符串的其余部分都被提取。对于多字节字符集(MBCS),nCount指的是每8位字符的数目;也就是说,在一个多字节字符中开始和结尾字节被算作两个...
This method extracts a substring of lengthnCountcharacters from thisCStringobject, starting at positionnFirst(zero-based). The method returns a copy of the extracted substring.Midis similar to the Basic MID$ function, except that indexes are zero-based. ...

Mid is similar to the Basic MID$ function (except that indexes are zero-based).For multibyte character sets (MBCS), nCount refers to each 8-bit character; that is, a lead and trail byte in one multibyte character are counted as two characters.Example...

CString Mid( int nFirst, int nCount ) const; nCount代表要提取的字符数, nFirst代表要提取的开始索引位置 例子 CString s( _T(“abcdef”) ); ASSERT( s.Mid( 2, 3 ) == _T(“cde”) ); CString::ReleaseBuffer void ReleaseBuffer( int nNewLength = -1 ); ...
CString Mid( int nFirst, int nCount ) const; nCount代表要提取的字符数, nFirst代表要提取的开始索引位置 例子 CString s( _T("abcdef") ); ASSERT( s.Mid( 2, 3 ) == _T("cde") ); CString::ReleaseBuffer void ReleaseBuffer( int nNewLength = -1 ); ...
Mid Extracts the middle part of a string (like the Basic MID$ function). Left Extracts the left part of a string (like the Basic LEFT$ function). Right Extracts the right part of a string (like the Basic RIGHT$ function). SpanIncluding Extracts a substring that contains only the character...
