Comparing two arrays in vb.net
提问by Random User
I need to do Reverse Intersectionoperation with two arrays and save the result in a different array
我需要对两个数组进行反向交集操作并将结果保存在不同的数组中
Eg: Array A {1, 2, 3}; Array B {1, 2, 3, 4, 5, 6} Resultant Array Should be {4, 5, 6}
例如：数组 A {1, 2, 3}; 数组 B {1, 2, 3, 4, 5, 6} 结果数组应该是 {4, 5, 6}
I Tried out the following logic but didn't work
我尝试了以下逻辑但没有用
int k = 0;
int a[2] = {1,10};
int p[10];
int roll[10] = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10};
for (int i = 0; i < 2; i++)
{
for (int j = 1; j <= 10; j++)
{
if (a[i] == roll[j])
{
break;
}
else
{
p[k] = 0;
p[k] = roll[j];
k++;
}
}
}
I need it for my vb.net project

I don't understand how that C# code is related to your VB.NET problem, if you only want to find integerswhich are in one array and not in the other, use Enumerable.Except:
我不明白该 C# 代码与您的 VB.NET 问题有何关联，如果您只想查找integers在一个数组中而不在另一个数组中的内容，请使用Enumerable.Except：
Dim intsA = {1, 2, 3}
Dim intsB = {1, 2, 3, 4, 5, 6}
Dim bOnly = intsB.Except(intsA).ToArray()

Try something like this if you can't use Linq:
如果您不能使用 Linq，请尝试以下操作：
Function RevIntersect(arr1() As String, arr2() As String) As String()
Dim sResult, aux As New List(Of String)()
aux.AddRange(arr1)
aux.AddRange(arr2)
For Each elem As String In aux
If (Not arr1.Contains(elem) OrElse Not Arr2.Contains(elem)) AndAlso _
Not sResult.Contains(elem) Then
sResult.Add(elem)
End If
Next
Return sResult.ToArray()
End Function
