.net - MemoryStream上的BinaryReader保持为空

            SyncLock _client.GetStream
                Dim bArray() As Byte
                Dim bWriter As New BinaryWriter(_client.GetStream)

                Dim bf As New BinaryFormatter
                Dim mStream As New MemoryStream

                bf.Serialize(mStream, dSet)

                'Send tagIdentifier
                bWriter.Write(bTag)
                'Send the Object length
                bWriter.Write(CInt(mStream.ToArray.Length))

                'It's not null, value of 3024
                Console.WriteLine("Mstream : " & mStream.ToArray.Length)

                'Initialize the BinaryReader
                Dim bReader As New BinaryReader(mStream)
                Do
                    bArray = bReader.ReadBytes(1024)
                    ''''''''''''''bArray stay at 0'''''''''''''''
                    bWriter.Write(bArray)
                Loop While bArray.Length = 1024

                bWriter.Flush()
            End SyncLock

所以我有这段代码，我要做的是发送一个序列化的数据集。
因此，我将序列化的数据集放入一个memorystream中，并将其转换为一个字节数组，以便用binarywritter发送它。
此外，即使msteam的值为3024，binaryreader指针似乎仍保持在0

最佳答案

由于您刚刚写入了memoryStream，所以指针位于没有可读取内容的末尾。在尝试读取之前，将位置重置为0（零）：

    mStream.Position = 0
