Get an array of bytes from a datagridview

Question

I have a datagridview that are connected to a table in SQL database. There is a column of type VARBINARY(MAX) that store a sequence of bytes. How can I extract these bytes from the grid view?

my code is:

byte [] a = datagridview.CurrentRow.Cells[4].Value;

in which cell[4] contain the bytes.

but it gives an error:

cannot implicitly convert type Object To byte[]

Answer 1

Try casting the right hand side like this

byte [] a = (byte [])datagridview.CurrentRow.Cells[4].Value;
