title: C# - How do I check if a file exists in a certain directory (based on its content, not the file name)?
body: <p>I am creating a program that will grab files from a Result Directory (Original Folder) and move those files to a Working Directory (Another Folder). Here the file's name is being changed when the file is moved from one directory to another. Before I move them, I need to check that the Working Directory does not contain that file I am trying to move already. Since the file name is being changed, I need something that will check if the file exists already based on the content inside of the file.</p>
  
  <p><strong>Let's say I have:</strong></p>
  
  <p><em>FilesRD</em> - (The files in the Original Folder/Result Directory)<br>
  <em>FilesWD</em> - (The files in the Other Folder/Working Directory)</p>
  
  <p><strong>and the files inside of those directories will look like this...</strong></p>
  
  <p><strong>Before</strong> (In Result Directoy):<br>
  Log_123.csv</p>
  
  <p><strong>After</strong> (In Working Directory):<br>
  Log_123_2015_24_6.csv</p>
