vb。net产生10到100的随机数

我的编程时这样的，但是产生的数之间没有空格分不清楚，哪位高手帮我改改Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim str As Integer
Dim randObj As New Random()
For i As Integer = 1 To 10
str &= Int(Rnd() * (100 - 11) + 10)
Next
Label2.Text = str
End Sub
End Class

Answer 1

你可以把str &= Int(Rnd() * (100 - 11) + 10)改成str = str&space（空格数）&Int(Rnd() * (100 - 11) + 10)如果语句有错的话就把以上函数值转化成字符串类型。

Answer 2

在产生随机数那个语句后加个分号试试

Answer 3

Dim str As String
Dim randObj As New Random()
For i As Integer = 1 To 10
str &= Int(Rnd() * (100 - 11) + 10) & ","
Next
Label2.Text = str

这样可以吗
