加载文件 [英] Load file

问题描述

我正在尝试从下拉列表中加载文件，但是我收到错误说

需要虚拟路径。选择的示例值将是

" ../ 4900 / myfile.doc"。任何想法 - 我的代码是。


Dim sumfin As String = DropDownList1.SelectedValue.ToString

Dim pos As Integer = sumfin.Length

Dim bString As String = sumfin.Substring（3，pos - 3）

Dim cString As String =" http：// localhost /" &安培; bString

Server.Transfer（cString）

I am trying to load a file from a dropdownlist, however I get a error saying
a virtual path is required. An example selected value would be
"../4900/myfile.doc". Any ideas - my code is.

Dim sumfin As String = DropDownList1.SelectedValue.ToString
Dim pos As Integer = sumfin.Length
Dim bString As String = sumfin.Substring(3, pos - 3)
Dim cString As String = "http://localhost/" & bString
Server.Transfer(cString)

推荐答案

虚拟路径为：


Dim cString As String =" /" &安培; bString


试试吧。


或者你可以去：

Response.Redirect（cString）


PS


这是'某事'而不是''sumfin'';）

A virtual path would be:

Dim cString As String = "/" & bString

Try that.

Alternately you could go:
Response.Redirect(cString)

P.S.

It''s ''something'' and not ''sumfin'' ;)

尝试使用Server.MapPath（bString）
