我试过搜索这个,但大多数人只想将十六进制值转换为它们的ASCII等价物.这不是我想要做的.
我想看看VB.NET是否有一个简单的内置函数来执行此操作：
Private Function NibbleToString(ByVal Nibble As Byte) As String
Dim retval As String = String.Empty
Select Case Nibble
Case &H0
retval = "0"
Case &H1
retval = "1"
Case &H2
retval = "2"
Case &H3
retval = "3"
Case &H4
retval = "4"
Case &H5
retval = "5"
Case &H6
retval = "6"
Case &H7
retval = "7"
Case &H8
retval = "8"
Case &H9
retval = "9"
Case &HA
retval = "A"
Case &HB
retval = "B"
Case &HC
retval = "C"
Case &HD
retval = "D"
Case &HE
retval = "E"
Case &HF
retval = "F"
End Select
Return retval
End Function
是否有更优雅的方式来完成与该代码相同的事情？

原文链接：https://www.f2er.com/vb/255055.htmlX format specifier一起使用ToString：
Dim b As Byte = &HA3
Console.WriteLine(b.ToString("X")) ' displays "A3"
Dim i As Integer = &H12AB89EF
Console.WriteLine(i.ToString("X")) ' displays "12AB89EF"
如果你只是想出于某种原因一次只做一个半字节,那么你可以事先掩盖/移出数字的各个位：
Dim b As Byte = &H5E
Console.WriteLine((b And &HF).ToString("X")) ' displays "E" (low nibble)
Console.WriteLine((b >> 4).ToString("X")) ' displays "5" (high nibble)
