--  [求助]串口字节发送问题

Dim ck As String = args(0)
Dim sj As String = args(1)
If ck > "" Then
If Ports.Contains(ck) Then
If Ports(ck).IsOpen Then
If sj.Split("-").Length > 1 Then
Dim Vs() As Byte
For i As Integer = 0 To sj.Split("-").Length - 1
Vs(i) = sj.Split("-")(i)
Next
Ports(ck).Write(Vs, 0, Vs.Length)
End If
End If
End If
End If

为什么上面这个自定义函数有问题，下面这个可以正常使用

Dim ck As String = args(0)
Dim sj As String = args(1)
If ck > "" Then
If Ports.Contains(ck) Then
If Ports(ck).IsOpen Then
If sj.Split("-").Length = 10 Then
Dim Vs() As Byte = New Byte() {sj.Split("-")(0),sj.Split("-")(1),sj.Split("-")(2),sj.Split("-")(3),sj.Split("-")(4),sj.Split("-")(5),sj.Split("-")(6),sj.Split("-")(7),sj.Split("-")(8),sj.Split("-")(9)}
Ports(ck).Write(Vs, 0, Vs.Length)
ElseIf sj.Split("-").Length = 12 Then
Dim Vs() As Byte = New Byte() {sj.Split("-")(0),sj.Split("-")(1),sj.Split("-")(2),sj.Split("-")(3),sj.Split("-")(4),sj.Split("-")(5),sj.Split("-")(6),sj.Split("-")(7),sj.Split("-")(8),sj.Split("-")(9),sj.Split("-")(10),sj.Split("-")(11)}
Ports(ck).Write(Vs, 0, Vs.Length)
End If
End If
End If
End If
