一、
CStdioFile
二、
FILE* f = fopen(“file name”, “mode”);
char buff[size];
fread(buff, size, 1, f);
fclose(f);
三、
//用MFC讀文件
CFile file(“yourfile.txt”,CFile::modeRead);
char *pBuf;
int iLen=file.GetLength();
pBuf =new char[iLen 1];
file.Read(pBuf,iLen);
pBuf[iLen]=0;
file.Close();
MessageBox(pBuf);
四、
//用C SDK 讀文件
HANDLE hFile;
hFile=CreateFile(“2.txt”,GENERIC_READ,0,NULL,OPEN_EXISTING,FILE_ATTRIBUTE_NORMAL,NULL);
char ch[100];
DWORD dwReads;
ReadFile(hFile,ch,100,&dwReads,NULL);
CloseHandle(hFile);
ch[dwReads]=0;
MessageBox(ch);*
五、
用C讀文件
FILE *pFile=fopen(“1.txt”,”rb”);
char *pBuf;
fseek(pFile,0,SEEK_END);//移動文件指針到文件末尾
int len=ftell(pFile);//獲取當前文件指針在文件中的偏移量,Gets the current position of a file pointer.offset
pBuf=new char[len];
rewind(pFile);//將指針移動到文件頭,Repositions the file pointer to the beginning of a file
//也可以用fseek(pFile,0,SEEK_SET);
fread(pBuf,1,len,pFile);
pBuf[len]=0;
fclose(pFile);
MessageBox(pBuf);
