Using vb.net ReadAllBytes
提问by user1642036
I used vb .NET function ReadAllBytes to read a file and send it over a socket. When received, I used WriteAllBytes. The problem is they are not same size! The original is 16kb, but the received data is 24kb. My code is below. What am I doing wrong?
我使用 vb .NET 函数 ReadAllBytes 读取文件并通过套接字发送它。收到后，我使用了 WriteAllBytes。问题是它们的大小不一样！原来是16kb，但是接收到的数据是24kb。我的代码如下。我究竟做错了什么？
Dim bteRead() As Byte
Try
bteRead = IO.File.ReadAllBytes(filepath)
Catch ex As System.IO.IOException
End Try
Return bteRead
then i convert bytes to string and send it , and when received i convert it back from string to bytes and do the WriteAllBytes
然后我将字节转换为字符串并发送它，当收到时我将它从字符串转换回字节并执行 WriteAllBytes
Dim str As String = a(1)
Dim encod As New System.Text.UTF8Encoding
Dim byteData() As Byte = encod.GetBytes(str)
IO.File.WriteAllBytes("c:\lol.db", byteData)

Solution for me was to change:
我的解决方案是改变：
Dim encod As New System.Text.UTF8Encoding
Dim byteData() As Byte = encod.GetBytes(str)
To
到
Dim byteData() As Byte = System.Text.Encoding.Default.GetBytes(str)
