title: Removing duplicates from a list collection
body: <p>Hope someone can help me. I am using c# and I am somewhat new to it.
  I am loading a text file into my app and splitting the data on "," I am reading part of string into a <code>&lt;list&gt;</code> when the data is read there is a lot of duplicates that vary depending on the txt file that I load.  Can someone tell me how to check the  and remove any and all duplicates that come up. There is no way of knowing what duplicates will show up as there is infinite possibilities that it could be.</p>
  
  <p>Thanks for the help in advance</p>
