基本上我在VB.NET中搜索一个字节数组,使用以下代码:
For i As Integer = 0 To message.Length - 1
If message(i) = Asc(ControlChars.Cr) Then
If message(i + 1) = Asc(ControlChars.Lf) Then
If message(i + 2) = Asc(ControlChars.Cr) Then
If message(i + 3) = Asc(ControlChars.Lf) Then
start = i + 4 ' take into account the above characters
Exit For
End If
End If
End If
End If
Next
Dim length As Integer = message.Length - start
我想知道是否有更好的方法可以做到这一点?我尝试过这样的事情:
start = message.IndexOf({ControlChars.CrLf, ControlChars.CrLf})
但返回-1。
另外,有没有更好的方法从字节数组中去除字节,我有这个:
Dim text(message.Length - start) As Byte
Dim position As Integer = 0
For i As Integer = start To message.Length - 1
text(position) = message(i)
position = position + 1
Next
