从数据库到Gridview的显示/存储和检索图像数据

Hi,

You may see my article if could help...
Display/Store and Retrieve Image Data from Database to Gridview

Happy coding...

尝试一下，

在数据库中有一列数据类型为 varbinary 的列，将图像转换为字节并将其存储在数据库中.
进行检索的同时，将内容放入字节数组并将其写入具有图像扩展名的文件中，然后就可以使用该图像.

try this,

have a column with a datatype varbinary in the database,convert the image to bytes and store it in the database.
while retriving get the thing in a byte array and write it to a file with image extension then you can use the image.
