'List(Of Byte())' to 'Byte()' in VB.NET
提问by Shahriyar
I have a list of bytes:
我有一个字节列表：
Public Function GenPackets()
Dim Stream As NetworkStream = ConnectionSocket.GetStream()
Dim DataList As New List(Of Byte())
Dim Data As Byte()
DataList.Add(IntegerToByte(My.Settings.BotUID))
' TO DO Stream.Write(Data, 0, 3)
Return Data
End Function
How can I convert DataListand all of its bytes to a single Byte() for use in Stream.Write?
如何将DataList其所有字节转换为单个 Byte() 以供使用Stream.Write？

No need to convert your data, just iterate over the list:
无需转换您的数据，只需遍历列表：
For Each buffer As Byte() In Datalist
yourStream.Write(buffer)
Next
This is vastly more efficient than first concatenating all the individual arrays to create one big array.
这比首先连接所有单个阵列以创建一个大阵列要高效得多。

As Konrad Rudolph already wrote, you don't need to flatten the data in order to write it to your stream.
正如康拉德·鲁道夫 (Konrad Rudolph) 已经写过的那样，您无需将数据展平即可将其写入您的流中。
For the sake of completeness, you can flatten your data list like this
为了完整起见，您可以像这样展平数据列表
Dim dataList As New List(Of Byte())
Dim data As Byte()
data = dataList.SelectMany(Function(x) x).ToArray()
Or with the LINQ syntax
或者使用 LINQ 语法
data = (From bytes In dataList From x In bytes Select x).ToArray()

You could do the Listof Bytes instead of arrays:
您可以使用ListBytes 而不是数组：
Dim DataList As New List(Of Byte)
DataList.AddRange(IntegerToByte(My.Settings.BotUID))
Data = DataList.ToArray()
