推荐答案

亲爱的朋友，

存储在数据库中的图片无法保留或插入到数据集列中，因为图像是一个流对象，只有在连接打开并且数据集处于断开连接模式时才能读取.

您必须使用sql datareader对象才能从数据库中读取图像:-)，因为它与db保持连接，直到未从数据库中读取全部内容为止.


希望对您有所帮助.

谢谢

Dear Friend,

A picture stored in database can''t be kept or inserted into a dataset column as the image is a stream object which can be only read if the connection is open and dataset works into a disconnected mode.

You have to use sql datareader object in order to read image from the database :-) as it maintains a connection with the db till the time whole content is not read from the database.


I hope this will help you out.

Thanks
