在Delphi的数字之前"$"是什么意思？

Question

我正在尝试将Delphi代码转换为vb.net,我不确定这一行:

stream.Seek($42, soFromBeginning);

我熟悉在文件流上使用搜索(在vb.net中),但我不确定$42.

我假设这对应于某个职位,但这又如何转化为vb.net？

Answer 1

$是十六进制常量的前缀.在VB.NET中,那是&H,所以你会写&H42.

Answer 2

The code required for VB.net is almost identical:

stream.Seek(&H42, SeekOrigin.Begin)

The points of note here are:

• $ in Delphi is the prefix for hexadecimal.
• The soFromBeginning corresponds to SeekOrigin.Begin.
