vb.net矩阵的问题

要实现什么样的功能呢?矩阵就是二维表吧,在.Net中有许多方法可以实现二维表,根据不同的需求选择适合的方法,你应该详细一点说明

VB.NET的题目 利用随机数生成两个4*4的矩阵A~~紧急紧急

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

MsgBox(Int(Rnd() * 10))

Dim n As Integer = 4

Dim i, a As Integer

Dim r As String

Randomize()

For i = 1 To n

r = Int(Rnd() * 10)

Label1.Text = Space(n - i + 1) StrDup(i, r) + vbNewLine

Next i

For i = n To 1 Step -1

r = Int(Rnd() * 10)

Label1.Text = Space(n - i + 1) StrDup(i, r) + vbNewLine

Next i

For Each c In Label1.Text

If IsNumeric(c) Then

a += 1

End If

Next

MsgBox(a) ‘主对角线和次对角线上各元素之和

End Sub

另一个矩阵也是用同样方法.

你说的是不是这样?
