昨天我问过这个问题,不过没人回答到点上,今天搞定了.贴出来给觉得有用的朋友,希望其他朋友不用走弯路.

'文件内容读取.
Function LoadFile(ByVal File)
Dim objStream
On Error Resume Next
Set objStream = Server.CreateObject("ADODB.Stream")
If Err.Number=-2147221005 Then
Response.Write "<div align='center'>非常遗憾,您的主机不支持ADODB.Stream,不能使用本程序</div>"
Err.Clear
Response.End
End If
With objStream
.Type = 2
.Mode = 3
.Open
.LoadFromFile Server.MapPath(File)
If Err.Number<>0 Then
Response.Write "<div align='center'>文件<font color='#ff0000'>"&File&"</font>无法被打开，请检查是否存在!</font></div>"
Err.Clear
Response.End
End If
.Charset = "GB2312"
.Position = 2
LoadFile = .ReadText
.Close
End With
Set objStream = Nothing
End Function
