CFile::Read
virtual UINT Read( void* lpBuf, UINT nCount );
throw( CFileException );

Return Value

The number of bytes transferred to the buffer. Note that for all CFile classes, the return value may be less than nCount if the end of file was reached.

Parameters

lpBuf

Pointer to the user-supplied buffer that is to receive the data read from the file.

nCount

The maximum number of bytes to be read from the file. For text-mode files, carriage return–linefeed pairs are counted as single characters.

Remarks

Reads data into a buffer from the file associated with the CFile object.

Example

//example for CFile::Read
extern CFile cfile;
char pbuf[100];
UINT nBytesRead = cfile.Read( pbuf, 100 );

CStdioFile fText;
BOOL bExist = fText.Open("unit3.txt",CFile::modeRead);
if (bExist)//判断这个文件必须存在，不然要出错
{
while(NULL != fText.ReadString(strFile))
{
//do sth.
}
}

CStdioFile功能比较强些，当然用CFile也可以的。
