使用Do While循环从打开的文件中逐条读取记录。以下能够正确读取数据的程序段是
A．Open "c:\File1．txt" For Input As #1 Do While Not EOF() Line Input #1， strLine Loop
B．Open "c:\File1．txt" For Input As#1 Do While Not EOF(#1) Line Input #1， strLine Loop
C．FileNo=FreeFile Open FileNo For Input As #1 Do While Not EOF(FileN Line Input #1， strLine Loop
D．FileNo=FreeFile Open FileNo For Input As #1 DoWhile Not EOF(#FileN Line Input #1， strLine Loop
