答案:VB.NET 代码:Dim HexString As String = "4F75" Dim BinaryString As String = Convert.ToString(Convert.ToInt32(HexString, 16), 2) 二进制:0100111101110101
### 回答2:
在VB.NET中,可以使用Convert.ToByte方法将十六进制字符转换为二进制。下面是将4组十六进制字符转化为二进制的VB.NET代码示例:
```vb
Dim hexString As String = "ABCDEF0123456789" ' 十六进制字符
Dim binaryString As String = ""
For i As Integer = 0 To hexString.Length - 1 Step 4 ' 每4个字符一组
Dim hexGroup As String = hexString.Substring(i, 4) ' 提取每组字符
Dim byteValue As Byte = Convert.ToByte(hexGroup, 16) ' 将十六进制字符转换为字节
Dim binaryGroup As String = Convert.ToString(byteValue, 2).PadLeft(8, "0"c) ' 将字节转换为二进制
binaryString += binaryGroup ' 将每组二进制拼接起来
Next
Console.WriteLine(binaryString) ' 输出结果
```
该代码将字符串中的每4个字符作为一组进行处理。首先,使用Convert.ToByte方法将十六进制字符转换为字节,然后使用Convert.ToString方法将字节转换为二进制字符串。最后,将每组二进制字符串拼接起来,得到最终结果。您可以将要转换的十六进制字符存储在hexString变量中,并根据需求使用binaryString变量进行后续操作。

要将4组十六进制字符转化为二进制,可以使用VB.NET编写以下代码:
```vb.net
Imports System
Public Module HexToBinaryConverter
Public Sub Main()
Dim hexStrings As String() = {"AF", "B4", "1E", "C3"}
For Each hexString As String In hexStrings
Dim binaryString As String = HexToBinary(hexString)
Console.WriteLine("Hexadecimal: {0}, Binary: {1}", hexString, binaryString)
Next
End Sub
Public Function HexToBinary(hexString As String) As String
Dim binaryString As String = ""
For Each digit As Char In hexString
Select Case digit
Case "0"
binaryString += "0000"
Case "1"
binaryString += "0001"
Case "2"
binaryString += "0010"
Case "3"
binaryString += "0011"
Case "4"
binaryString += "0100"
Case "5"
binaryString += "0101"
Case "6"
binaryString += "0110"
Case "7"
binaryString += "0111"
Case "8"
binaryString += "1000"
Case "9"
binaryString += "1001"
Case "A", "a"
binaryString += "1010"
Case "B", "b"
binaryString += "1011"
Case "C", "c"
binaryString += "1100"
Case "D", "d"
binaryString += "1101"
Case "E", "e"
binaryString += "1110"
Case "F", "f"
binaryString += "1111"
Case Else
Console.WriteLine("Invalid hex digit: {0}", digit)
End Select
Next
Return binaryString
End Function
End Module
```
这段代码首先在`hexStrings`数组中定义了4个要转换的十六进制字符串。接下来,通过`For Each`循环遍历每个十六进制字符串。然后,调用`HexToBinary`函数将每个字符转换为二进制字符串,并输出结果。
`HexToBinary`函数使用`For Each`循环遍历十六进制字符串中的每个字符。对于每个字符,使用`Select Case`语句将其转换为二进制字符串,然后将其追加到`binaryString`变量中。最后,返回`binaryString`作为结果。
运行上述代码将输出如下结果:
```
Hexadecimal: AF, Binary: 10101111
Hexadecimal: B4, Binary: 10110100
Hexadecimal: 1E, Binary: 00011110
Hexadecimal: C3, Binary: 11000011
```
以上就是将4组十六进制字符转化为二进制的VB.NET代码。注意,该实现假设输入的十六进制字符是有效的。如果遇到无效的十六进制字符,将在控制台输出相应的错误信息。
