在ASP中处理大型文本文件的读写可以通过以下几种方式实现:
Set objFSO = CreateObject("Scripting.FileSystemObject")
Set objFile = objFSO.OpenTextFile("C:\example.txt", 1, True)
Do While Not objFile.AtEndOfStream
Response.Write objFile.ReadLine
Loop
objFile.Close
Set objFile = Nothing
Set objFSO = Nothing
Set objStream = Server.CreateObject("ADODB.Stream")
objStream.Type = 2 'binary
objStream.Open
objStream.LoadFromFile "C:\example.txt"
Response.BinaryWrite objStream.Read
objStream.Close
Set objStream = Nothing
Set objFSO = CreateObject("Scripting.FileSystemObject")
Set objFile = objFSO.GetFile("C:\example.txt")
Set objTextStream = objFile.OpenAsTextStream(1, -2)
Do While Not objTextStream.AtEndOfStream
Response.Write objTextStream.ReadLine
Loop
objTextStream.Close
Set objTextStream = Nothing
Set objFile = Nothing
Set objFSO = Nothing
通过以上方法,可以在ASP中处理大型文本文件的读写操作。根据具体需求和文件大小选择合适的方法来实现。
