-- 在字符窜里，怎么保证唯一值呢？
字符窜是用 “,” 分割的。
dim des as string ="1,2,1,3,5,6,7"
1是重复的， 怎么才能删除呢？
*重复可能多个

Dim des As String = "1,2,1,3,5,6,7"
Dim ary() As String = des.Split(",")
Dim ls As new List(of String)
For Each s As String In ary
If ls.Contains(s) = False Then
ls.Add(s)
End If
Next
msgbox(ls.count)

我想要的效果 是 这个
Dim des As String = "1,2,1,1,1,1,1,1,3,53,53,53,53,53,5,5,56,7"
Dim des2 As String
Dim ary() As String = des.Split(",")
Dim ls As new List(of String)
For Each s As String In ary
If ls.Contains(s) = False Then
ls.Add(s)
des2 + = "," & s
End If
Next
des2 = des2.Trim(",")
msgbox(des2)
