Question

假设我有字符串“A3C0”，我想将它的二进制值存储在布尔数组中。

转换后（从字符串到二进制）结果应为= 1010001111000000

然后我想将它存储在这个数组中，

dim bits_array(15) as Boolean

最后：

bits_array(0)=0
bits_array(1)=0
 .
 .
 .
 .
bits_array(15)=1

我该怎么做？

Answer 1

这很容易。

Function HexStringToBinary(ByVal hexString As String) As String
    Dim num As Integer = Integer.Parse(hexString, NumberStyles.HexNumber)
    Return Convert.ToString(num, 2)
End Function

样本用法：

Dim hexString As String = "A3C0"
Dim binaryString As String = HexStringToBinary(hexString)
MessageBox.Show("Hex: " & hexString & "    Binary: " & binaryString)

要将二进制数字输入数组，您只需执行以下操作：

Dim binaryDigits = HexStringToBinary(hexString).ToCharArray

Answer 2

让s为值 A3C0 的输入字符串，output是存储输出的变量。循环将迭代输入中的每个字母并将其存储在临时变量temp中。现在看代码：

Dim s As String = "A3C0"
Dim output As String = ""
Dim temp As String = ""
For i As Integer = 1 To Len(s)
    temp = Mid(s, i, 1)
    output = output & System.Convert.ToString(Asc(temp), 2).PadLeft(4, "0")
    ' converting each letter into corresponding binary value
    'concatenate it with the output to get the final output 
Next
MsgBox(output)' display the binary equivalent of the input `s` 
Dim array() As Char = output.ToArray()' convert the binary string  to binary array

希望这实际上是你所期待的。
