如何在数据库中显示图像到Gridview（ASP.NET 2.0） [英] How to Display an image, from a DB, into the Gridview (ASP.NET 2.0)

问题描述

您好，


我想知道如何将图像显示到Gridview（ASP.NET 2.0）

直接从DataBase中获取，不使用URL，如本文所述：
文章：

http://msdn.microsoft.com/library/de...idViewEx06.asp


我没有URL，我在DB中有二进制图像，就像表格中的字段Photo

Employees一样。 NWIND.MDB中的NWIND.MDB数据库。

任何提示？


谢谢，

自动。

解决方案

您创建一个从数据库中打开图像的aspx，更改

响应类型和response.write（）图像。 （另一个选项是

常用的是使用HTTPHandler返回图像）


然后为此图像添加指向此aspx页面的链接好像这是一个正常的

图像。

就是一个例子。


干杯，

Hello,

I would like to know how do display an image into a Gridview (ASP.NET 2.0)
taken directly from a DataBase, NOT using an URL, like described in this
article:

http://msdn.microsoft.com/library/de...idViewEx06.asp

I have NO URL, i have the binary image inside the DB, like the field "Photo"
in the table "Employees" of the "NWIND.MDB" DataBase.
Any hints?

Thanks,
Auto.

解决方案

You create an aspx that opens the image from the database, changes the
response type and response.write() the image. (Another option that is
commonly used is to use a HTTPHandler to return back the image)

You then place a link to this aspx page for your image as if it was a normal
image.

http://www.aspfree.com/c/a/ASP.NET/R...--C---Part-II/
is an example.

Cheers,

Greg

Personal web starter kit has a http handler that does exactly that. You can
download the starter kit and look at the code.
