楼主
自学的VB.net，做一个解线性方程组问题。
界面如下：
Public Class Form1
Public i, j, n As Integer
Public a(n, n), p As Double
Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
For i = 1 To n
For j = 1 To n
a(i, j) = InputBox("请输入a" & i & j, "输入元素")
Next j
Next i
End Sub
Private Sub Button2_Click(sender As Object, e As EventArgs) Handles Button2.Click
n = Val(InputBox("请输入矩阵阶数", "输入数据"))
End Sub
出现了这样的问题，自己理解了下是在一个过程中给全局变量赋值出现了问题，求教啊。
End Class
