Use textual representations of LINQ expressions

Question

In my project, I use many LINQ expressions, and I would allow users to enter their own queries by typing linq query in text input

So, is it possible to create a LINQ expression from text containing this? And besides, is it possible to get the text equivalent of a linq request? (for example, from FOO in the bar, select foo)

thanks in advance

Answer 3

Is it possible that you can provide your users with a copy of LinqPad (which is free), and they can create their own queries and also see the equivalent of SQL text?

LinqPad can be found here

Answer 4

You can also consider Dynamic LINQ. It is still linked to VS2010 (anyway in the Samples folder), although it is not very well documented. Here's a brief introduction:
