问题描述
我在mainpage.aspx上点击了一个按钮。我想显示一个新的
网页，它只有我的图像，这是一个jpg。我希望页面是一个

我怎么能这样做吗？
谢谢，
T
I''m in a button clicked event on mainpage.aspx. I want to display a new
webpage that has just my image, which is a jpg. I want the page to be a
..jpg not an aspx so that it will be easy for the user to save to disk.
How can I do this?
Thanks,
T
推荐答案
更改ContentType并写入jpeg。
Response.ContentType =" image / jepg"
...
oBmp =新位图（strPath）
...
oBmp.Save（Response.OutputStream，
System.Drawing.Imaging。 ImageFormat.Jpeg）

涉及两个页面，webform1.aspx和HiRes.aspx。在
Webform1.aspx我写了一个.jpg到d的根：并执行：
Server.Transfer（" HiRes.aspx"）
HiRes.aspx如下：
<％@ Page Language =" vb"的ContentType = QUOT;图像/ JPEG" AutoEventWireup =" false"
Codebehind =" HiRes.aspx.vb" Inherits =" DBAPhotoQuery.HiRes"％>
<！DOCTYPE HTML PUBLIC" - // W3C // DTD HTML 4.0 Transitional // EN">
< html>
< head>
< title> test< / title>
< meta name =" GENERATOR" ; content =" Microsoft Visual Studio .NET 7.1"
< meta name =" CODE_LANGUAGE" content =" Visual Basic .NET 7.1"
< meta name = vs_defaultClientScript content =" JavaScript">
< meta name = vs_targetSchema < br $>
content =" http://schemas.microsoft.com/intellisense/ie5">
< / head>
< body MS_POSITIONING =" GridLayout">
< form id =" Form1"目标= QUOT; _blank"方法= QUOT;交" runat =" server">
< / form>
< / body>
< / html>
和hires.aspx的CodeBehind如下：
Imports System.Drawing.Imaging
Public Class HiRes
Inherits System.Web.UI.Page
Private Sub Page_Load（ByVal sender As System.Object，ByVal e As
System.EventArgs）处理MyBase.Load
Response.Clear（）
Dim oBmp As Bitmap
oBmp =新位图（" d：\ bigpic.jpg"）
oBmp.Save（Response.OutputStream，imageformat.jpeg）
Response.End（）
结束次级
结束班级
会发生什么事情，图片确实写完了但是
webform1的.aspx。 webform1.aspx中的内容完全被
图像取代。你可能会注意到我把Target =" _blank"试图获得它
来显示一个新的ie页面。
谢谢，

there are two pages involved, webform1.aspx and HiRes.aspx. In
Webform1.aspx I write a .jpg to the root of d: and do :
Server.Transfer("HiRes.aspx")
HiRes.aspx is as follows:
<%@ Page Language="vb" ContentType="image/jpeg" AutoEventWireup="false"
Codebehind="HiRes.aspx.vb" Inherits="DBAPhotoQuery.HiRes"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<html>
<head>
<title>test</title>
<meta name="GENERATOR" content="Microsoft Visual Studio .NET 7.1">
<meta name="CODE_LANGUAGE" content="Visual Basic .NET 7.1">
<meta name=vs_defaultClientScript content="JavaScript">
<meta name=vs_targetSchema
content="http://schemas.microsoft.com/intellisense/ie5">
</head>
<body MS_POSITIONING="GridLayout">
<form id="Form1" target="_blank" method="post" runat="server">
</form>
</body>
</html>
and the CodeBehind for hires.aspx is as follows:
Imports System.Drawing.Imaging
Public Class HiRes
Inherits System.Web.UI.Page
Private Sub Page_Load(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles MyBase.Load
Response.Clear()
Dim oBmp As Bitmap
oBmp = New Bitmap("d:\bigpic.jpg")
oBmp.Save(Response.OutputStream, imageformat.jpeg)
Response.End()
End Sub
End Class
What happens is that the picture does indeed get written but to
webform1.aspx. What was in webform1.aspx is completely replaced by just the
image. You might notice that I put Target="_blank" in an attempt to get it
to display a new i.e. page.

它是什么来的？你清楚地告诉客户它是一个
图像/ jpeg并且你正在保存它并且我一直这样做
并且它工作得很好。你可以再详细一点吗？也许你比对照片保存更多
或者你没有正确设置标题......

What does it come as? You''re clearly telling the client that it''s an
image/jpeg and you''re saving it as such and I''m doing this all the time and it works just fine. Could you be more specific? Maybe you''re saving more
than the image to the response or you''re not setting the headers right...

Natty，
那不是'以.jpg格式进入客户端浏览器并且
Natty,
That doesn''t come through to the client browser as a .jpg and is there
前
要么不可能，要么很难将文件保存为.jpg。
either impossible or very difficult for them to save the file as a .jpg.
我
从静态页面一直这样做，但似乎无法通过aspx页面和vb.net代码使它工作
。
