[Post=10]下面提供一个函数。 - (defun _ReadStream ( path len / fso file stream result )
- ;; If the file is successful read the data is returned as
- ;; a string. Won't be tripped up by nulls, control chars
- ;; including ctrl z (eof marker). Pretty fast (feel free
- ;; to bench mark / compare to alternates).
- ;;
- ;; If the caller wants the result as a list of byte values
- ;; simply use vl-string->list on the result:
- ;;
- ;; (setq bytes
- ;; (if (setq stream (_ReadStream path len))
- ;; (vl-string->list stream)
- ;; )
- ;; )
- ;;
- ;; Arguments:
- ;;
- ;; path <duh>
- ;; len Number of bytes to read. If non numeric, less
- ;; than 1 or greater than the number of bytes in
- ;; the file everything is returned.
- (vl-catch-all-apply
- '(lambda ( / iomode format size )
- (setq
- iomode 1 ;; 1 = read, 2 = write, 8 = append
- format 0 ;; 0 = ascii, -1 = unicode, -2 = system default
- fso (vlax-create-object "Scripting.FileSystemObject")
- file (vlax-invoke fso 'GetFile path)
- stream (vlax-invoke fso 'OpenTextFile path iomode format)
- size (vlax-get file 'Size)
- len (if (and (numberp len) (< 0 len size)) (fix len) size)
- result (vlax-invoke stream 'read len)
- )
- (vlax-invoke stream 'Close)
- )
- )
- (if stream (vlax-release-object stream))
- (if file (vlax-release-object file))
- (if fso (vlax-release-object fso))
- result
- )
