lambda-expressions

I have a method Get on a type MyType1 accepting a Func<MyType2, bool> as a parameter.

An example of its use:

mytype1Instance.Get(x => x.Guid == guid));

I would like create a stub implementation of the method Get that examines the incoming lambda expression and determines what the value of guid is. Clearly the lambda could be "anything", but I'm happy for the stub to make an assumption about the lambda, that it is trying to match on the Guid property.

How can I do this? I suspect it involves the use of the built-in Expression type?

Dynamic Type to do away with Reflection

The dynamic type in C# 4.0 is a welcome addition to the language. One thing I’ve been doing a lot with it is to remove explicit Reflection code that’s often necessary when you ‘dynamically’ need to walk and object hierarchy. In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More
