2.Add slides in ppt at runtime using C#

Very Simple Two Steps:

Step1. On Button click we are calling the IsEqual method with two ppt input parameters. Chage the file name according if required.

        protected void Button1_Click(object sender, EventArgs e)

        {

             IsEqual(Server.MapPath("~/App_Data/Temp.ppt"), Server.MapPath("~/App_Data/Temp2.ppt"));

        }

Step2. Add this piece of code. 

         private bool IsEqual(string ppt1, string ppt2)

        {

            byte[] ppt1byte = File.ReadAllBytes(ppt1);

            byte[] ppt2byte = File.ReadAllBytes(ppt2);

            if (ppt1byte.Length == ppt2byte.Length)

            {

                for (int i = 0; i < ppt1byte.Length; i++)

                {

                    if (ppt1byte[i] != ppt2byte[i])

                    {

                        return false;

                    }

                }

                return true;

            }

            return false;

        }
