Question

我想制作一个能在文本框中显示结果的生成器，我想让它随机选择0或1，我该怎么做？

Kode有效：

Public Class Form1
Private Sub Button1_Click(ByVal sender As Object, ByVal e As EventArgs) Handles Button1.Click

Dim r as New Random()
Dim n As Integer = r.Next(2)
TextBox1.Text = CStr(n) 

    End Sub
End Class

Answer 1

尝试以下

Dim r as New Random()
Dim n As Integer = r.Next(2)
TextBox1.Text = CStr(n)

Answer 2

您可以使用.NET Framework中包含的Random class。它有一个名为Next的实例方法，它接受最小/最大值。这是一个例子：

Public Class Form1
Private Sub Button1_Click(ByVal sender As Object, ByVal e As EventArgs) Handles Button1.Click
    Dim rng As Random = New Random()
    Dim randomNumber As Integer = rng.Next(0,2)
    ' Do what you want with randomNumber from here...
End Sub
End Class
