Uploading image to database is not a normal practice but in some situations we need it, in my previous blog many people request to write to store the image into database, first of all, I would like to thanks for all those emails and interest in my blogs and site. I am going to change the database structure a little bit but use the same modal to post the data from view to controller which we used in previous blog, there is no change into create view.
Before jumping to the coding part I would like to point out what you need to be careful when you are going to store the files into database. First of all we will see the table structure to store the product detail with image, to store image what would be the best data type we need to use, let's see available data types to store image or file.
Avoid using these data types in new development work, and plan to modify applications that currently use them. Use nvarchar max , varchar max , and varbinary max instead. So we will use varbinary max , the good thing is that, even if your data type is image, the same code will work because we will send the byte array from model to data, so it's up to you what you want to use, here is the table structure of products.
We need to change our post method to save the image into database than resize in two different sizes and save into folder and update image path into database. I am not going to save two different version of image into database, if you want you can do it easy, see the previous blog to rezie the image.
Before looking into complete post method let's check how we can get the byte array from posted data. We are reading all the bytes by using BinaryReader from the posted file in model. I am not going to show how to edit the record, you can try it to learn, let me know if there is anything you need more detail.
Otherwise any user can fill your database with huge files and your application will be very very slow. MVC display image from database. MVC upload image to database mvc save image database asp.
Before jumping to the coding part I would like to point out what you need to be careful when you are going to store the files into database when you store the image into table every record will be huge due to image bytes It's good to keep the image into a separate table so retrieval of record on that table cannot affect Keeping separate table also give option to store as many image for a single record as we wan, by using the primary key and foreign key First of all we will see the table structure to store the product detail with image, to store image what would be the best data type we need to use, let's see available data types to store image or file.
Add product ; db. Image' convert byte array to base64 string, if we want, we can create a method somewhere or on top of the page now convert base64 string to image format and store into imgSrc this imgSrc will be used as the image path to bind see the image tag src attribute. If you want to see the complete listing page html then it is here: We need to be careful to restrict the use to upload Maximum number of images Maximum size of image Type of images Otherwise any user can fill your database with huge files and your application will be very very slow.
