Dim array2() As Boolean

Dim i As Integer

Dim j As Integer

Dim str1 As String = "a,c,c,c,a,b,c,d,f,eee,eee"

array1 = Split(str1, ",")

str1 = ""

ReDim array2(UBound(array1))

For i = 0 To UBound(array1)

array2(i) = False

Next

For i = 0 To UBound(array1) - 1

If array2(i) = False Then

For j = i + 1 To UBound(array1)

If array1(i) = array1(j) And array2(j) = False Then

array2(j) = True

End If

Next j

End If

Next i

For i = 0 To UBound(array1)

If array2(i) = False Then

str1 = str1 array1(i) ","

End If

Next i

If str1 "" Then

str1 = Strings.Left(str1, Len(str1) - 1)

End If

VB中如何删除数组变量中重复的元素?

Private Function NewArray(ByRef b() As Integer)

Dim Temp() As Integer

Dim H As Integer, I As Integer, J As Integer, K As Integer

Dim IsNew As Boolean

H = UBound(b())

ReDim Temp(0) '如果你原数组元素数量是万个级别的，就直接ReDim Temp(H)，下面 ReDim Preserve Temp(K) 去掉

Temp(0) = b(0)

For I = 0 To H

IsNew = True

For J = 0 To K

If Temp(J) = b(I) Then

IsNew = False

Exit For

End If

Next J

If IsNew Then

K = K + 1

ReDim Preserve Temp(K)

Temp(K) = b(I)

End If

Next I

ReDim b(K)

For I = 0 To K

b(I) = Temp(I)

Next I

Erase Temp()

End Function

'调用

'dim b() as integer

'dim I as integer

'dim OutputStr as String

'redim b(Ubound(a()))

'for I=0 TO Ubound(a())

' b(I)=a(I)

'next I

'NewArray(b())

'返回的b()为除重后的数组，可以根据你的需要显示、输出数组a()、b()。

VB.Net去除数组中重复的字符的元素？

比如数组a。里面有5个值，其中有3个是重复的？

如果这样的话，很好办哦。

新建一个数组b，然后遍历要去除的数组a，

从a中把每一个都取出来，和新建的b里面的去比，如果有相同的，则不放入b，

否则就放入数组b，直到循环结束。
