<br>内容：你写错了，看MSDN上的解释<BR><BR>int GetLength( ) const;<BR><BR>Return Value<BR><BR>A count of the bytes in the string.<BR><BR>Remarks<BR><BR>Call this member function to get a count of the bytes in this CString object. The count does not include a null terminator.<BR><BR>For multibyte character sets (MBCS), GetLength counts each 8-bit character; that is, a lead and trail byte in one multibyte character are counted as two bytes.<BR><BR>
