How can I make a console application that lets me enter LINQ expressions and my program will execute them?

Question

How can I write a console application that prompts me and lets me enter LINQ expressions and it will spit out the results of that LINQ query?

What would be the easiest way to parse/evaluate a incoming string as a LINQ expression?

Answer 1

Console app is to awkward to use for thousands of reasons. Try LinqPad

Answer 2

I wrote LinqFilter for something similar to this purpose. It does no parsing of LINQ query expressions on its own, but rather sends the code off to the C# v3.5 compiler via Microsoft.CSharp.CSharpCodeProvider to compile into a dynamic assembly and executes the compiled method containing the query. If you were looking for a more interactive approach to designing LINQ queries over databases, LinqPad would be the better tool.
