如何将VB.NET 字符串转换成字节数组
ToCharArray()
例如:str="asdfafafafaf"
str.toCharArray就是一个Char()数组了。

Q1: 如何将VB.NET字符串转换成字节数组
1、字节数组转换为字符串
byte[] byBuffer = new byte[20];
String strRead = new String(byBuffer);
strRead = String.copyValueOf(strRead.toCharArray(), 0, byBuffer.length]);
2、字符串转换成字节数组
byte[] byBuffer = new byte[200];
String strInput=abcdefg;
byBuffer= strInput.getBytes();
注意:如果字符串里面含有中文,要特别注意,在android系统下,默认是UTF8编码,一个中文字符相当于3个字节,只有gb2312下一个中文相当于2字节。这种情况下可采取以下办法:
Q2: vb.net ,如何把字节数组转成字符串数组?
Dim arr1() As Byte = {HA, H0, H1, H3}
MsgBox(CStr(arr1(0)))
Q3: vb.net 字节数组补0
'写入
Dim bytes() As Byte = {34, 23, 43, 43, 55, 3}
Dim items = (From item In bytes Select item.ToString("000")).ToArray()
System.IO.File.WriteAllLines("c:\test.txt", items)
'读取
Dim items2 = System.IO.File.ReadAllLines("c:\test.txt")
Dim bytes2 = (From item In items2 Select Byte.Parse(item)).ToArray()
For Each item In bytes2
Console.WriteLine(item.ToString())

Q4: 刚入手VB.NET不知道怎么将数字转换成字节数组
Private Function Conver_Hex(ByVal L As Long) As Array
Dim str_L As String = Hex(L)
If str_L.Length \ 2 0 Then
str_L = "0" str_L
End If
Dim byt(str_L.Length / 2 - 1) As Byte
For i = 0 To str_L.Length / 2 - 1
byt(i) = Convert.ToByte(str_L.Substring(2 * i, 2), 16)
Next
Return byt
End Function
'下面是调用代码
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim L As Double = 123456
Dim byt() As Byte = Conver_Hex(L)
End Sub
