Задать презентацию PowerPoint с значениями базы данных

Question

Где-то в моем приложении мне нужно создать слайды PowerPoint и заполнить его значениями DB. Я могу создать слайды с помощью локального шаблона. Но я не понимаю, как заполнить его значениями DB. Я искал веб-сайт и нашел this, но это не помогает мне. График или график я не хочу заполнять. Это простой текст, основанный на значениях DB.
Может кто-нибудь помочь мне здесь?

Этот следующий код позволяет создать новый слайд, выбрать его и добавить значения в таблицу. Вам просто нужно сейчас, чтобы прочитать DB и заполнить его в

int newaddslidecounter = 0; // checking how many new slides have to be inserted in order to split the table 
int startmultiplicator=1; // used in order to return current table row that must be pasted in new table 
int amountrowsshown =7; // amount of shown rows per table 
int fontsize = 12; 
// set position of new table/chart 
int topsize = 100; 
int leftsize = 100; 
int widthsize = 150; 
int heightsize = 150; 
Boolean alreadycreated = false; // checks if a table has already been created 
//Resizing all tables 
//and insert new Excel table instead while importing data from Excel table 
//used for visualization of data 
foreach (PowerPoint.Slide slide in presentation.Slides)

       { 
        //Console.WriteLine("Shape type : " + pptshape.Type.ToString());

        //in order to do the manipulation
