如何使用VB6将文本文件加载到字符串中

Question

如何使用 VB6 快速将文本文件加载到字符串中？

Answer 1

这是在 VB6 中加载整个文件的最快方法，无需逐行加载：

Function FileText (filename$) As String
    Dim handle As Integer
    handle = FreeFile
    Open filename$ For Input As #handle
    FileText = Input$(LOF(handle), handle)
    Close #handle
End Function

Answer 2

Public Function ReadFileIntoString(strFilePath As String) As String

    Dim fso As New FileSystemObject
    Dim ts As TextStream

    Set ts = fso.OpenTextFile(strFilePath)
    ReadFileIntoString = ts.ReadAll

End Function 

Answer 3

这是使用文件系统对象执行此操作的一种方法：

Public Function ReadTextFileIntoString(strPathToFile as String) as String
  Dim objFSO As New FileSystemObject
  Dim objTxtStream As TextStream        
  Dim strOutput as String
  Set objTxtStream = objFSO.OpenTextFile(strPathToFile)
  Do until objTxtStream.AtEndOfStream
   strOutput = strOutput + objTxtStream.ReadLine
  Loop

  objTxtStream.Close
  ReadTextFileIntoString = strOutput
End Sub
