Error cannot implicity convert type byte[] to byte

I have a class named animal, it have public string name, species, and public Byte photoAnimal.

In another form I create animal named Simba,and i want to set the value of Simba but when I want to set the photoAnimal I get error. I use filestream and binaryreader to read the data, then create byte[] imageData = binary data from filestream and binary reader. I cant set the Simba.photoAnimal = imageData, here's some of my code:

    animal Simba = new animal();
    string fileName = textBox5.Text;
    byte[] ImageData;
    fs = new FileStream(fileName, FileMode.Open, FileAccess.Read);
    br = new BinaryReader(fs);                    
    ImageData = br.ReadBytes((int)fs.Length);
    br.Close();
    fs.Close();    
    Simba.name = textBox1.Text;
    Simba.species = textBox2.Text;
    Simba.photoAnimal = ImageData; // error

The error message means it cannot assign your ImageData (of type byte[]) to photoAnimal, which seems to be of type byte

In your class animal, change the type of photoAnimal to an array :

public class animal
{
    public byte[] photoAnimal;
}

As a side note, you inverted the naming convention. variables should be in camelCase and classes in UpperCamelCase. Instead of animal Simba = new animal(), in C# you normally use Animal simba = new Animal()

ImageData is a byte[]. So in the animal class, replace

public Byte photoAnimal

by

public Byte[] photoAnimal.
