asp .net / sql / image数据类型问题 [英] asp .net / sql / image data type question

问题描述

大家好，


我发布这个大约一周后没有回复，所以我想再次尝试
。关于使用sql image

数据类型，我有一个奇怪的问题。我知道如何拍摄图像类型并将其转换为屏幕上的

图片。我所拥有的是这样一种情况，我需要从一个数据库中读取图像数据，存储它，然后将其上传到另一个数据库的
。我尝试将它存储在viewstate和一个字节

变量中。我不知道我是在丢失lenth属性还是什么，但是

我无法将数据从一个数据库传输到另一个数据库。所以一旦我从一个sql数据库中读出了图像数据类型，我可以保存什么样的asp .net变量

，这样我就可以将它写入另一个数据库了？谢谢大家！

Hi all,

I posted this about a week back with no response so I want to try
again. I have a weird questions in regards to working with sql image
data types. I know how to take the image type and convert it into a
picture on the screen. What I have is a situation where I need to read
the image data from one database, store it, and then upload it to
another database. I tried storing it in viewstate and in a byte
variable. I don''t know if I am loosing the lenth property or what, but
I cannot get the data from one database to another. So once I read
IMAGE data type out of an sql database, what kind of asp .net variable
can I save it to so I can write it into another database? Thanks all!

推荐答案

我认为要走的路是：将数据从DB读取到字节[]

（字节数组）使用StreamReader和向后。


干杯

I think the way to go is: reading the Image data from the DB to the byte[]
(byte array) using StreamReader and backwards.

Cheers

我很感谢建议伙伴。


Pat，


您正在向我展示如何从SQL图像类型显示图片。我已经成功实现了这个
。我需要知道如何将这些信息转移到另一个

数据库的另一个表中的另一列。应该很容易，但我不知道该怎么做。


Alex444，


我不明白你怎么做你的建议。我会做一些

搜索。如果你能给我一个更多的例子，我会非常感激。
很感激。


再次感谢所有人。你们很棒。

Pat写道：

I appreciate the advise guys.

Pat,

You are showing me how to display a picture from SQL image type. I have
successfully implemented this already. I need to know how to transfer
this information into another column in another table in another
database. Should be easy, but I am not sure how to.

Alex444,

I do not understand how to do what you have suggested. I will do some
searches. If you could give me more of an example, I would GREATLY
appreciate it.

Thanks again all. You guys are great.
