I am trying to transfer list of persons from wcf service to application. but when i bind image array with data then "maxReceivedMessageSize" issue raised. I have given multiple values but all in vain.

But actual problem is not only this because i have to transfer result of search of person and there can be multiple record set return. So i have to handle multiple Image array.

Solution required:

I want a proper way to transfer data from wcf service to application so that it can handle as many as possible Image arrays.

Thanks in advance.

1. Increase maxReceivedMessageSize
2. Work with chunks...

If an image is a byte array
you could transfer an image collection as e.g. List<byte[]>

In the service contract interface of your WCF service
you could define a method e.g.

C#

[OperationContract]
List<byte[]> GetImages();

The implementation could be e.g.

C#

public List<byte[]> GetImages()
{
    List<byte[]> images = new List<byte[]>();

    images.Add(new byte[] { 0x20, 0x20, 0x20, 0x20, 0x20, 0x20, 0x20 });
    images.Add(new byte[] { 0x20, 0x20, 0x20, 0x20, 0x20, 0x20, 0x20 });
            
    return images;
}

This example uses dummy data,
it's up to you to add real data to the list.

If You hav a large amaount of data to transfer via WCF, You should take a look at streaming:
