简单的字串切割vb.net

原始字串aaaa,bbb,ddd,eee,sss,ffdsa

---------------切成以下两个字串-------------------

dim 字串1 as string=aaaa

dim 字串2 as string= or 0=bbb,|or 0=ddd,|or 0=eee,|or 0=sss,|or 0=ffdsa

字串1，就只有开头最前面的
字串2 串起来就比较特殊，用到 ,|or 0= 去做间隔

dim arr = split("aaaa,bbb,ddd,eee,sss,ffdsa", ",")
dim 字串1 as string= arr(0)

dim 字串2 as string= string.Join(",", arr.Skip(1).Select(Function(x) "|or 0=" + x).ToArray())

字串1 =mid(原始字串,1,4)
字串2=原始字串.replace(",",",|or 0 =")

Dim a() As String = System.Text.RegularExpressions.Regex.Split(TextBox1.Text, ",")
Dim 字符串1 As String = a(0)
Dim 字符串2 As String = "or 0="
For i = 1 To UBound(a)
If (i = 1) Then
字符串2 += a(i)
else
字符串2 += ",|or 0= " & a(i)
End If
