读写二进制文件 VB.NET

概述需要引入命名空间 Imports System.IO         '二进制流 转文件     Public Function BinaryToFile(ByVal byTmp As Byte(), ByVal path As String) As Boolean         Dim fs As FileStream         Dim bwr As BinaryWriter      

需要引入命名空间

imports System.IO

'二进制流 转文件
Public Function BinaryTofile(ByVal byTmp As Byte(),ByVal path As String) As Boolean
Dim fs As fileStream
Dim bwr As BinaryWriter

fs = New fileStream(path,fileMode.Create)
bwr = New BinaryWriter(fs)

bwr.Write(byTmp)
bwr.Flush()

bwr.Close()
fs.Close()
fs.dispose()

Return True
End Function

'文件转二进制流,读取文件二进制流
Public Function fileToBinary(ByRef byTmp As Byte(),ByVal path As String) As Boolean
Dim fs As fileStream
Dim br As BinaryReader

fs = New fileStream(path,fileMode.Open,fileAccess.Read)
br = New BinaryReader(fs)

byTmp = br.ReadBytes(fs.Length)

br.Close()
fs.Close()
fs.dispose()

Return True End Function
