摘要:Visual Basic 2005 - 讀取二進位檔的演進過程
在過去,我們會使用下列寫法來讀取二進位檔:
Dim fs As FileStream = New FileStream(ImageFilePath, FileMode.Open, FileAccess.Read)
Dim br As BinaryReader = New BinaryReader(fs)
Dim photo() As Byte = br.ReadBytes(fs.Length)
br.Close()
fs.Close()
自從 Visual Basic 2005 提供了 Using...End Using 之後,我們會改寫如下:
Dim photo As Byte()
Using fs As FileStream = New FileStream(ImageFilePath, FileMode.Open, FileAccess.Read)
Using br As BinaryReader = New BinaryReader(fs)
photo = br.ReadBytes(fs.Length)
End Using
End Using
但是別忘了,Visual Basic 2005 還提供了一個更便利的 My,所以,最簡易的寫法應該如下喔:
Dim photo As Byte()
photo = _
My.Computer.FileSystem.ReadAllBytes(ImageFilePath)
