mfc怎么把文件数据读到数组中？

Question

比如把这个数据读到数组中，给数组赋值，如a[0]=1,a[1]=2, a[9]=10, c++中可以 ifs>>a[i]循环，mfc应该怎么弄？

下面是《VC++深入详解》上读取文件的例子，最近正在看，正好用上

void CFileView::OnFileRead() 
{
/*    FILE *pFile=fopen("1.txt","r");
    char ch[100];
    memset(ch,0,100);
    fread(ch,1,100,pFile);
    fclose(pFile);    
    MessageBox(ch);*/
/*    char *pBuf;
    fseek(pFile,0,SEEK_END);
    int len=ftell(pFile);
    pBuf=new char[len+1];
    rewind(pFile);
    fread(pBuf,1,len,pFile);
    pBuf[len]=0;
    fclose(pFile);
    MessageBox(pBuf);
*/
/*    FILE *pFile=fopen("2.txt","rb");
    char ch[100];
    fread(ch,1,3,pFile);
    ch[3]=0;
    MessageBox(ch);
    fclose(pFile);*/
/*    ifstream ifs("4.txt");
    char ch[100];
    memset(ch,0,100);
    ifs.read(ch,100);
    ifs.close();
    MessageBox(ch);*/
/*    HANDLE hFile;
    hFile=CreateFile("5.txt",GENERIC_READ,0,NULL,OPEN_EXISTING,
        FILE_ATTRIBUTE_NORMAL,NULL);
    char ch[100];
    DWORD dwReads;
    ReadFile(hFile,ch,100,&dwReads,NULL);
    ch[dwReads]=0;
    CloseHandle(hFile);
    MessageBox(ch);*/
/*    CFile file("6.txt",CFile::modeRead);
    char *pBuf;
    DWORD dwFileLen;
    dwFileLen=file.GetLength();
    pBuf=new char[dwFileLen+1];
    pBuf[dwFileLen]=0;
    file.Read(pBuf,dwFileLen);
    file.Close();
    MessageBox(pBuf);*/

    CFileDialog fileDlg(TRUE);
    fileDlg.m_ofn.lpstrTitle="我的文件打开对话框";
    fileDlg.m_ofn.lpstrFilter="Text Files(*.txt)\0*.txt\0All Files(*.*)\0*.*\0\0";
    
    if(IDOK==fileDlg.DoModal())
    {
        CFile file(fileDlg.GetFileName(),CFile::modeRead);
        char *pBuf;
        DWORD dwFileLen;
        dwFileLen=file.GetLength();
        pBuf=new char[dwFileLen+1];
        pBuf[dwFileLen]=0;
        file.Read(pBuf,dwFileLen);
        file.Close();
        MessageBox(pBuf);
    }

}
