Can C# Expression Objects Be Serialized and Deserialized from a Database?

Exploring Expression Tree Serialization and Deserialization in C#

Question: Can Expression objects in C# be deserialized after being stored in a database?

Answer: Yes, it is possible to serialize and deserialize Expression objects in C#.

Solution: The ExpressionTree.Codeplex.com library offers a solution for this task. Originally introduced in 2008 but since abandoned, the library has been revived with updates to support .NET 4.0 and Silverlight.

Implementation Details:

This library addresses bugs in the original code and enhances its independence from specific data access layers (DALs). It enables the following functionality:

• Serialization: Expressions can be converted into a binary format for storage.
• Deserialization: The binary representation of Expressions can be retrieved and reconstructed into live Expression objects at runtime.

Availability:

The updated ExpressionTree library is available for download at ExpressionTree.Codeplex.com. It provides a convenient approach for storing and loading Expression objects, allowing for dynamic expression generation and evaluation at runtime.
