ImageValueConverter Class

A Value Converter which can be used to convert Image objects to an array of bytes.

Namespace: DevExpress.Xpo.Metadata

Assembly: DevExpress.Xpo.v21.2.dll


public class ImageValueConverter :


The following example shows how to convert the value of the Image property to an array of bytes when saving it in a data store.

using DevExpress.Xpo;

public class SampleImageClass : XPObject {
    private System.Drawing.Image image;
    public SampleImageClass(Session session) : base(session) {}

    public System.Drawing.Image Image {
        get { return image; }
        set {
            SetPropertyValue(nameof(Image) , ref image, value);

ImageValueConverter requires System.Drawing.Common 5.0+. In Xamarin/Mono projects, change your image property type from System.Drawing.Image to byte[].

using DevExpress.Xpo;

public byte[] Image {
    get { return GetDelayedPropertyValue(nameof(Image)); }
    set { SetDelayedPropertyValue<byte[]>(nameof(Image), value); }


To run your application on Linux and macOS, install libgdiplus.

macOS: brew install mono-libgdiplus.
