Post your code. Not clear

What does it mean "to binary"?! Is byte[] not binary enough?
Make no sense whatsoever.

For goodness sake, what error?

We need to know the error message, and the line which caused it.
In addition, we need a small amount of code around that line to give us some context for what the line is doing - if it is short enough, then the method should suffice.

Solution 1

found on CP: C# Save and Load Image from Database[^]

other example code:

C#

SqlCommand cmd = new SqlCommand("select StudImagefrom tablename where id = 1");
SqlDataReader dataReader = cmd.ExecuteReader();
byte[] imageBytes = (byte[]) imageReader.GetValue(0); 
MemoryStream ms = new MemoryStream(imageBytes); 
FileStream fs = File.OpenWrite(imagePath);fs.Write(ms.GetBuffer(), 0, ms.Position());
