GET byte array from SQL Server parameter in C#

I am trying to get a byte array from my SQL Server parameter. I get the data from SQL Server like this:

cmd.Parameters.Add("@Image1", SqlDbType.VarBinary).Size = 5000000;
cmd.Parameters["@Image1"].Direction = ParameterDirection.Output;

conn.Open();
cmd.ExecuteNonQuery();

string str = cmd.Parameters["@Image1"].Value.ToString();

I get the value System.Byte[] in string however I would need the whole byte array that I could store it as an image.

How would I do it using .Value returns an object would I convert that object to byte array?

You might be overthinking this:

byte[] imageArray = (byte[])cmd.Parameters["@Image1"].Value;

EDIT: Casted right hand side. Thanks JuanR.
