在.NET 中微软已经为我们内置了一些方法，我们可以直接使用该方法以快速达到我们的目的
Module Module1
Sub Main()
Dim a(3) As Int32
a(0) = 1
a(1) = 1
a(2) = 1
a(3) = 1
'推荐第一种方法
If a.Distinct().Count() = 1 Then
If a.All(Function(c) c = 1) Then
End If
End If
End Sub
End Module
第二种方法为LINQ，这是一种高级用法；是.NET 程序员必知必会的东西，如果不懂怎么用可以按F1查看官方文档
'''这个函数功能就是用来把数组转为string的格式'''如byte()={1,2,3,4,5,6}转化后变为",1,2,3,4,5,6,"Function ByteArrayToString(bytes() As Byte) As String Dim s As String = "" For i As Integer = 0 To bytes.Length s = Convert.ToString(bytes(i)) "," Next Return “," sEnd Function Sub Search()Dim a as byte()={1,2,3,4,5,6}
Dim b as byte()={2,3,4}
Dim astr As String = ByteArrayToString(a)Dim bstr As String = ByteArrayToString(b)Dim index As Integer = astr.IndexOf(bstr) '这个index就是b数组在a数组的位置，下标从0开始，不过记得处理下逗号，因为这时候是字符串。'''如果index小于0说明没有匹配内容End Sub 现在说明下ByteArrayToString为什么要在字符串开头加个","，如果不加，可能出现a="1,23,4,5,6,", b="3,4,5,"，结果导致查询位置错误，匹配了a的位置
dim a(3)
a(0) = 1,a(1)=1,a(2)=1,a(3)=0
for i = 0 to 3
if a(i)a(0) then msgbox "有不同"
next
Dim S As String()
Dim j As Integer = 9
ReDim S(j)
For i = 0 To j
S(i) = i
Next
注: 指定数组上限才能对其赋值
你只是定义了一个对象，类而已
首先要给对象设置变量，这个还不是数组
Public class As Single的class 应该是关键字请换一个名字
Dim KidsX(1 to 100) as kids
KidsX(1).classx=1
KidsX(1).grade=1
KidsX(1).name=”张某"
KidsX(2).classx=1
KidsX(2).grade=2
KidsX(2).name=”王某"
