Serializing and Deserializing Expression Trees in

Question

Is there a way to Deserialize Expressions in C#, I would like to store Expressions in a Database and load them at run time.

Answer 1

I continued work on the library that was mentioned by Serializing and Deserializing Expression Trees in C#

It looks like the project was abandoned (2008) but I did some work on it and now it works with .NET 4.0 and Silverlight. I made bug fixes to their code and also made it more DAL-independent.

Answer 2

have a look at my new library Serialize.Linq. It serializes linq expressions to json, xml and binary.

Answer 3

WCF RIA Services allows for serializing IQuerayble<T>

Answer 4

There's an project on GitHub/Nuget called MetaLinq that aims to make working with expression tress more easy.

It converts between normal Expressions and 'EditableExpressions' which are mutable and fully Serializable, so can be used with Json, Xml, Binary etc.

Answer 5

I was working on a project for serializing expressions. It's OK and you can use it. http://www.codeproject.com/Articles/851187/ServicePredicateBuilder-for-creating-Serializable

Answer 6

Not in full; however, the Dynamic LINQ sample may help a bit. You can certainly serialize an expression to a string (to an extent - generics look a bit screwy), but there is no inbuilt parser.
