Insert image into datagridview using byte

Open original thread
Hi,

I'm having a problem inserting a byte image into my datagridview;

Firstly Form Class:

Dim imgbyte As Byte() = Nothing


Form Load:

table.Columns.Add("Image", GetType(Byte()))


Button to generate data to datagridview;

table.Rows.Add(GetType(Byte)


Button2 to add image to picturebox1 as byte;

If OpenFileDialog1.ShowDialog = vbOK Then

        End If

        Dim myimage As Image = Image.FromFile(OpenFileDialog1.FileName)

        Dim imagestream As System.IO.MemoryStream = New System.IO.MemoryStream

        myimage.Save(imagestream, System.Drawing.Imaging.ImageFormat.Jpeg)
        imgbyte = imagestream.GetBuffer

        PictureBox1.Image = Drawing.Image.FromStream(imagestream)




I then get the following error:

An unhandled exception of type 'System.ArgumentException' occurred in System.Data.dll

Additional information: Type of value has a mismatch with column typeCouldn't store <System.Byte> in Image Column.  Expected type is Byte[].


Which flags the following line;

table.Rows.Add(GetType(Byte)


Anyone able to advise?
