How can I add an Image type to an EF4 Code First Entity? I need to add a column for thumbnail images.

public Image Thumbnail { get; set; }

Thanks!

回答1:

Images are represented as binary in EF 4

You will need to do something like this

public Binary Thumbnail {get; set}

Then convert the image to binary

This reference will help you with the image to binary conversion http://www.dotnetspider.com/resources/6150-Convert-Image-binary-format.aspx

回答2:

public System.Data.Linq.Binary Thumbnail {get; set}

For those wondering where the type Binary is located, also i belive you can use byte[]
