Your question is unclear. Are you asking how to filter the list to show just those items mentioned in the second half of your post? What "formatting" are you trying to accomplish?

<div>
format is not the correct word. &nbsp;it is like comparing each row with all other rows <br />
<br />
because the 3rd value &quot;Orders&quot; and 2nd value &quot;Orders.Order_Details&quot; <br />
exists in the 1st value &quot;Orders.Order_Details.Prod<wbr />uct.Suppli<wbr />er&quot;<br />
<br />
and 4th value &quot;Orders.Employee&quot; does not exists in any other rows. i will be as it is.<br />
<br />
so, results will be like this<br />
<br />
Orders.Order_Details.Produ<wbr />ct.Supplie<wbr />r<br />
Orders.Employee
</div>


format is not the correct word.  it is like comparing each row with all other rows

because the 3rd value "Orders" and 2nd value "Orders.Order_Details"
exists in the 1st value "Orders.Order_Details.Product.Supplier"

and 4th value "Orders.Employee" does not exists in any other rows. i will be as it is.

so, results will be like this

Orders.Order_Details.Product.Supplier
Orders.Employee

<div class="content wysiwyg-content">

how to format the data into like the following using linq or other method<br />

Most development for the Microsoft platform is done utilizing the technologies supported by the.NET framework. Other development is done using Visual Basic for Applications (VBA) for programs like Access, Excel, Word and Outlook, with PowerShell for scripting, or with SQL for large databases.

Microsoft Development

C# is an object-oriented programming language created in conjunction with Microsoft’s .NET framework. Compilation is usually done into the Microsoft Intermediate Language (MSIL), which is then JIT-compiled to native code (and cached) during execution in the Common Language Runtime (CLR).

The .NET Framework is not specific to any one programming language; rather, it includes a library of functions that allows developers to rapidly build applications. Several supported languages include C#, VB.NET, C++ or ASP.NET.

.NET Programming

Language Integrated Query (LINQ) is a Microsoft .NET Framework component that adds native data querying capabilities to .NET languages, although ports exist for Java, PHP, JavaScript and ActionScript. LINQ extends the language by the addition of query expressions, which are akin to SQL statements, and can be used to conveniently extract and process data from arrays, enumerable classes, XML documents, relational databases, and third-party data sources.
