主题：如何判断两个集合是否相同

如何判断两个集合是否相同：

Dim Names1 As New List(Of String)
Names1.Add( "电视机")
Names1.Add("电冰箱")
Names1.Add("洗衣机")
Dim Names2 As New List(Of String)
Names2.Add( "电视机")
Names2.Add("电冰箱")
Names2.Add("洗衣机")

If names1.count <> names2.count Then
    Return False
Else
    For i As Integer = 0 To names1.count-1
        If names1(i) <> names2(i) Then
            Return False
        End If
    Next
End If
Return True

Dim Names1 As New List(Of String)
Names1.Add( "电视机")
Names1.Add("电冰箱")
Names1.Add("洗衣机")
Dim Names2 As New List(Of String)
Names2.Add( "电视机")
Names2.Add("洗衣机")
Names2.Add("电冰箱")

If names1.count <> names2.count Then
    Return False
Else
    For i As Integer = 0 To names1.count-1
        If names1.Contains(names2(i)) = False Then
            Return False
        End If
    Next
    For i As Integer = 0 To names1.count-1
        If names2.Contains(names1(i)) = False Then
            Return False
        End If
    Next
   
End If
Return True

 Dim Names1 As New List(Of String)
Names1.Add( "电视机")
Names1.Add("电冰箱")
Names1.Add("洗衣机")
Dim Names2 As New List(Of String)
Names2.Add( "电视机")
Names2.Add("电冰箱")
Names2.Add("洗衣机")
If names1.count <> names2.count Then Return False
If String.Join("",names1.ToArray()) <> String.Join("",Names2 .ToArray()) Then Return False
