title: C#, Two lists of object find differences between one variable in both objects
body: <p>I have a program that parses two files (.txt and .xls), stores various different fields into objects </p>
  
  <pre><code>List&lt;AcsRecord&gt; Textrecords = AcsFileParser.Parsefile(path1);
  List&lt;ExcelRecord&gt; Execelrecords = excelFileParser.Parsefile(path2);
  </code></pre>
  
  <p>As an example the AcsRecord is:</p>
  
  <pre><code>public string EID {get; set;}
  public string Name {get; set;}
  </code></pre>
  
  <p>Excel records has a similar Name record. I want to, in main find all of those names found in the AcsRecord that are not found in Excelrecord. Using linq join, I can only find those which are equal. I am unsure of how to reference just the name field in each record. Maybe something like !contains() ?
  Thanks.</p>
