<blockquote>
<p>Sometimes you have a string field in your files that can be better handled if you map it to an enum.</p>
<p>Thanks to <b>Derek Fluker,</b> you can automatically use an enum without defining any
converter. The FileHelpers library parses the field and performs a case insensitive
comparison to the enum values and assigns the correct one.</p>
<p>The customer file is an excellent sample:</p>
${Input.txt}
<p>The enum is:</p>
${TheEnumerator.cs}
<p>When defining your record class use the enum:</p>
${Customers with Enum.cs}
<p>Done !! you parse the file with:</p>
${RunEngine.cs}

<blockquote>
<p>The idea of this engine is to parse files with different record types
(this engine doesn't use any hierarical structure like the master-details,
all the records are in linear relation for it).</p>
<p>With the MultiRecordEngine you can parse also mixed delimited and fixed
length records. For example, you can parse this strange file:</p>
${Input.txt}
<p>This file contains <b>three</b> record types; Customers (begins with letters, | delimited),
Orders (begin with numbers, ';' delimited) and the sample type of the first example.</p>
<p>To work with this engine you must create one instance of it in this way:</p>
${RunEngine.cs}
<p>In the res array you have all the records in the file, each one with the corresponding type.</p>
<p>And the Selector Method looks like this:</p>
${Selector.cs}
<p> here are the three classes that read the different records</p>
${Customer.cs}
<br/><br/>
${SampleType.cs}
<br/><br/>
${Orders.cs}
<p>Hope you find this useful.</p>
