什么二进制数组？

http://www.foxtable.com/help/topics/2950.htm

直接保存成字符。参考

Dim str As String = "联想Aabc"
Dim bs() As Byte = Encoding.Unicode.GetBytes(str)
Dim nstr As String = ""
For Each b As Byte In bs
    nstr &= b.ToString("x") & ","
Next
nstr = nstr.Trim(",")
output.show(nstr)

'----------------转回去

Dim strAry() As String = nstr.Split(",")
Dim bys(strAry.Length-1) As Byte
For i As Integer = 0 To strAry.Length - 1
    Bys(i) = Byte.Parse(strAry(i), System.Globalization.NumberStyles.HexNumber)
Next
Dim bstr As String = Encoding.Unicode.GetString(bys)
output.show(bstr)

1、保存的时候转成字符串。

2、还原的时候，没必要转成字符串

那你也可以存入二进制列，但要用sql的update语句，把字符合并成如 0x5480F3604100 后保存。
