今天查了几个C段打算扫下端口但手头也没有生成C段的工具就没事自己搞了个比较简单for嵌套

Public Class Form1
    Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
        If RichTextBox1.TextLength > 0 Then
            RichTextBox1.Text = String.Empty
        End If
        For z As Integer = CInt(TextBox2.Text) To CInt(TextBox3.Text)
            For i As Integer = 0 To 255
                If z = CInt(TextBox3.Text) And i = 255 Then
                    RichTextBox1.AppendText(TextBox1.Text & "." & z & "." & i)
                Else
                    RichTextBox1.AppendText(TextBox1.Text & "." & z & "." & i & vbCrLf)
                End If
            Next
        Next
    End Sub
End Class
