storing byte array as column value in datatable using c#

This post covers following objective
1. How to declare and define datatable
2. Add columns at runtime
3. Add column to store byte array (image/file etc)

//YOUR PHOTOGRAPH HERE

MemoryStream ms = new MemoryStream();
argPhotograph.Save(ms, System.Drawing.Imaging.ImageFormat.Gif);

//DECLARING DATATABLE

DataTable dt = new DataTable();

 
dt.Columns.Add("ID");
dt.Columns.Add("Name");
dt.Columns.Add("CreatedOn", typeof(DateTime));

dt.Columns.Add("Photograph", typeof(byte[]));

//METHOD 1: ADDING DATA 

DataRow row = null;

row = dt.NewRow();
row["ID"] = 1;
row["Name"] = "Usman";
row["CreatedOn"] = DateTime.Now;

row["Photograph"] = argPhotograph.ToArray(); 

dt.Rows.Add(row); 

//METHOD 2: ADDING DATA 
dt.Row.Add(1, "Usman", DateTime.Now, argPhotograph.ToArray());
