How Do I Add Doc File In Datagridview

// Save the document to a MemoryStream object.
MemoryStream stream = new MemoryStream();
doc.Save(stream, SaveFormat.Doc);

string fileName = Path.GetFileName(doc.OriginalFileName);

// Create the SQL command.
row.Cells[1].Value =stream.ToArray(;

// Add the @Doc parameter.
command.Parameters.AddWithValue("Doc", stream.ToArray());

// Write the document to the database.
command.ExecuteNonQuery();
