--  找出两个字符串的差异

Dim des As String = "1,2,1,1,1,1,1,1,3,53,53,53,53,53,5,5,56,7"
Dim des1 As String = "1,2,1,1,1,1,1,1,3,53,53,53,53,53,5,5,56,7,530"

怎么才能删除两个字符串相同值呢？

结果应该是 530

replace(\'acb\',\'a\',\'\')
结果 cb

没那么简单...

Dim des As String = "1,2,1,1,1,1,1,1,3,53,53,53,53,53,5,5,56,7"
Dim des1 As String = "1,2,1,1,1,1,1,1,3,53,53,53,53,53,5,5,56,7,530"

MessageBox.Show(des1.Replace(des,"").Remove(0,1))
你看看是不是这样？

也不是哦，

Dim des As String = "1,2,1,1,1,1,1,1,3,53,53,53,53,53,5,5,56,7"
Dim des1 As String = "1,2,1,1,1,1,1,1,3,53,53,53,53,53,5,5,56,7,530"

只是单纯的为了方便复制后添加 530的···

des 和 des1 可能不同的数字会更多...

我的思路是，分割后一个个对比，但·· 不是那么顺利..
