如何用vb点虐 向串口发送十六位进制数据

下面代码就是将文本框中以一个空格隔开的十六进制转为字节的代码，文本框中数字格式为：01 02 03

Dim TestArray() As String = Split(TextBox1.Text)

Dim hexBytes() As Byte

ReDim hexBytes(TestArray.Length - 1)

Dim i As Integer

For i = 0 To TestArray.Length - 1

hexBytes(i) = Val("h" TestArray(i))

Next

SerialPort.Write(hexBytes, 0, hexBytes.Length)
