title: Auto read data from excel when data is modified
body: <p>I am developing a <code>C#</code> application to read data from an <code>Excel</code> file. The file is updated from another application. I need to execute my <code>C#</code> code each time the <code>Excel</code> file is modified, read data from it, and process the data. </p>
  
  <p>I searched and find codes to read data from <code>Excel</code>.</p>
  
  <p>Is there any way by which I can execute my <code>c#</code> code when <code>Excel</code> file is modified? 
  (like scheduling a job or something like that)</p>
