基本上我在 VB.NET 中搜索一个字节数组,代码如下:
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来做到这一点?我试着做这样的事情:
start = message.IndexOf({ControlChars.CrLf, ControlChars.CrLf})
但这会返回-1。
另外,有没有更好的方法从字节数组中删除字节,因为我有这个:
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
