Asp.net将pdf文件上传到服务器 [英] Asp.net upload pdf file to the server

问题描述

我有以下内容：

Response.Write（Request.Headers（X-File-Name））



Dim input As Stream = DirectCast（Request.InputStream，Stream）

Dim bmp As New Bitmap（输入）



Response.Clear（）

Response.ContentType =image / jpeg



'保存到Response.OutputStream对象

bmp .Save（C：\inetpub \ www.root \ mywerver \ upload \& Request.Headers（X-File-Name）&.jpg）



bmp.Dispose（）



可以正常上传图片，但如果我想上传其他像PDF这样的扩展程序，那么它就不会工作。



我尝试了什么：



我试过：回复.ContentType =application / pdf和

bmp.Save（C：\inetpub\wwwroot\mywerver\upload \& Request .Headers（X-File-Name）&。pdf）

但没有运气。

感谢您的帮助

HI I have the following:
Response.Write(Request.Headers("X-File-Name"))

Dim input As Stream = DirectCast(Request.InputStream, Stream)
Dim bmp As New Bitmap(input)

Response.Clear()
Response.ContentType = "image/jpeg"

' Save to the Response.OutputStream object
bmp.Save("C:\inetpub\wwwroot\mywerver\upload\" & Request.Headers("X-File-Name") & ".jpg")

bmp.Dispose()

which work fine to upload images but if I want to upload some other extension like PDF, then it wont work.

What I have tried:

I tried : Response.ContentType = "application/pdf" and
bmp.Save("C:\inetpub\wwwroot\mywerver\upload\" & Request.Headers("X-File-Name") & ".pdf")
But no luck.
Thanks for any help

推荐答案

这适用于服务器上的任何文件类型

This will work with any file type on the server

Response.Write(Request.Headers("X-File-Name"))
            
Dim output As FileStream = File.Create(PathToFolderEndWithBackSlash & Request.Headers("X-File-Name"))
Dim input As Stream = DirectCast(Request.InputStream, Stream)
            
Dim buffer(input.Length - 1) As Byte
Dim bytesRead As Integer
               
Do
   bytesRead = input.Read(buffer, 0, buffer.Length)
   If bytesRead = 0 Then Exit Do
   output.Write(buffer, 0, bytesRead)
Loop

output.Close()

虽然我敢于你想要添加错误捕获等等

though I dare asy you'll want to add error catching etc etc
