Question

我有一个应用程序，用户可以上传和下载文件，但是在上传和下载文本文件时我遇到了问题。在下载文件后查看文件时，我可以在顶部看到文件的原始内容，但是下面是从下载页面的html内容？

以下是下载的逻辑：

''' <summary>
''' Downloads a file to the browser
''' </summary>
''' <param name="serverFilePath"></param>
Public Sub DownloadFile(serverFilePath As String)

    Dim fileName As String = Path.GetFileName(serverFilePath)
    Dim ext As String = Path.GetExtension(serverFilePath)

    Dim context As HttpContext = HttpContext.Current
    Dim response As HttpResponse = context.Response
    response.BufferOutput = True
    response.Clear()
    'Returns the mime type for the given extension
    response.ContentType = MimeTypeHelper.GetMimeType(ext)
    response.AddHeader("Content-Disposition", "attachment; filename=" + fileName + ";")
    response.TransmitFile(serverFilePath)
    response.Flush()
    context.ApplicationInstance.CompleteRequest()

End Sub

有谁知道为什么会这样？

Answer 1

试试这个

response.ClearContent()
response.ClearHeaders()
response.AppendHeader("content-length", bytes.Length.ToString())
response.AppendHeader("Content-Disposition","attachment; filename=" + fileName + ";")
response.ContentType = MimeTypeHelper.GetMimeType(ext)
response.BinaryWrite(bytes) 'Where bytes is ann array of bytes representing the file
response.Flush()
response.Close()

为我工作
