Visual Basic 6.0 中的字符数组

本文介绍了Visual Basic 6.0 中的字符数组的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

考虑:

char [] chararray = txt1.Text;

我们如何在 Visual Basic 6.0 中做同样的事情?

How we do the same in Visual Basic 6.0?

推荐答案

这取决于你最终想要做什么.

That depends on what you eventually want to do.

例如，您可以在 VB6 中执行此操作:

You can, for example, do this in VB6:

Dim b() As Byte
b = Text1.Text

这样 b 数组将被调整大小以保存来自 "string" 的 Unicode 数据——但是每个字符将被分成两个字节，这可能不是你想要什么.此技巧仅适用于 Byte.

That way the b array will be resized to hold the Unicode data from "string" -- but then each character will be split across two bytes which is probably not what you want. This trick only works with Byte.

你也可以这样做:

Dim b() As Byte
b = StrConv(Text1.Text, vbFromUnicode)

现在每个字母将占用一个字节，但扩展字符将消失.仅当当前系统代码页包含所需字符时才执行此操作.

Each letter will now occupy one byte, but the extended characters will be gone. Only do this if the current system code page contains the required characters.

您可以手动将字符复制到数组中:

You can copy the characters manually to an array:

Dim s() As String, i As Long
ReDim s(1 To Len(Text1.Text))

For i = 1 To UBound(s)
  s(i) = Mid$(Text1.Text, i, 1)
Next

或者你甚至可以完全避免创建一个数组，因为 Mid 也可以作为一个索引操作符来改变一个字符，而不需要复制或分配任何东西:

Or you can even avoid creating an array at all, becase Mid also serves as an indexer operator that changes a character in place, without copying or allocating anything:

Dim s As String
s = Text1.Text

Mid$(s, 3, 1) = "!"
