比较具有不同维数的两个数组 [英] Compare two arrays with different dimension

问题描述

我正在尝试比较两个始终具有不同维度的数组.

I am trying to compare two arrays that always have different dimensions.

eg. arr1 -> {1,2,3} and arr2->{1,2}

我确实尝试过，并且能够将匹配项添加到新数组中.但我希望只得到无法比拟的物品

I did try and able to get the matching items to new array. But I am expecting to get the unmatched items only

我希望比较两个数组，仅将项目'3'放到arr1而不是arr2的新数组中

I am expecting to compare both arrays and put only the item '3' to a new array which is in arr1 and not in arr2

例如arr1-> {1,2,3}和arr2-> {1,2}应产生一个包含3的新数组 arr1-> {1,2,3,4}和arr2-> {1,2}应该得到3,4的数组

eg arr1 -> {1,2,3} and arr2->{1,2} should result a new array with 3 arr1 -> {1,2,3,4} and arr2->{1,2} should result a array with 3,4

是否有任何方法可以在不使用.net framework的较早版本进行此操作rel ="nofollow noreferrer">可枚举.除了

Is there any way of doing this for older version of .net framework without using Enumerable.Except

推荐答案

我已经做了类似的事情. 如果我们有两个分别称为paramOld {"1"，"2"，"3"}和paramNew {"2"，"3"}

I have done something like this. if we have two arrays called paramOld{"1","2","3"} and paramNew{"2","3"}

If paramOld.Length > paramNew.Length Then
            Dim paramDelete((paramOld.Length - paramNew.Length) - 1) As String


            Dim isFound As Boolean = False
            For i As Int32 = 0 To oldparamLenght - 1
                isFound = False
                For j As Int32 = 0 To newparamLength - 1
                    If paramOld(i) = paramNew(j) Then
                        isFound = True
                        Exit For
                    End If
                Next
                If isFound = False Then
                    paramDelete(i) = paramOld(i)
                End If
            Next
End If
