在文件夹中创建两个文本文件。
示范下面的内容
- FileSystemObject.CreateTextFile
- TextStream.WriteLine
- TextStream.Write
- TextStream.WriteBlankLines
- TextStream.Close


Sub CreateLyrics(Folder)

TextStream.WriteBlankLines(1)
TextStream.WriteLine("Id like to be under the sea in an octopus garden in the shade,")
TextStream.WriteLine("Hed let us in, knows where weve been -- in his octopus garden in the shade.")
TextStream.WriteBlankLines(2)

Set TextStream = Folder.CreateTextFile("BathroomWindow.txt")
TextStream.WriteLine("She Came In Through The Bathroom Window (by Lennon/McCartney)")
TextStream.WriteLine("")
TextStream.WriteLine("She came in through the bathroom window protected by a silver spoon")
TextStream.WriteLine("But now she sucks her thumb and wanders by the banks of her own lagoon")
TextStream.WriteBlankLines(2)
TextStream.Close

End Sub

示范下面的内容
- FileSystemObject.OpenTextFile
- FileSystemObject.GetFile
- TextStream.ReadAll

Function GetLyrics(FSO)

Dim TextStream
Dim S
Dim File

有多种方法可用来打开一个文本文件，和多种方法来从文件读取数据。
这儿用了两种方法来打开文件和读取文件：

Set TextStream = FSO.OpenTextFile(TestFilePath & "\Beatles\OctopusGarden.txt", OpenFileForReading)

S = TextStream.ReadAll & NewLine & NewLine
TextStream.Close

Set File = FSO.GetFile(TestFilePath & "\Beatles\BathroomWindow.txt")
Set TextStream = File.OpenAsTextStream(OpenFileForReading)
Do While Not TextStream.AtEndOfStream
S = S & TextStream.ReadLine & NewLine
Loop
TextStream.Close

GetLyrics = S

End Function
