How do I detect if a MemberExpression has a value that needs to be compiled/evaluated?

I have two separate member expression outputs, the first which has a value, and the second which doesn't. What is the best way to differentiate between the two?

exp
**{value(Microsoft.Connect.Api.Client.Tests.SearchQueryUnitTests+<>c__DisplayClass6).handle}**
    [System.Linq.Expressions.MemberExpression]: **{value(Microsoft.Connect.Api.Client.Tests.SearchQueryUnitTests+<>c__DisplayClass6).handle}**
    NodeType: MemberAccess
    Type: {Name = "String" FullName = "System.String"}

vs

exp
{x.CreatedBy}
    [System.Linq.Expressions.MemberExpression]: {x.CreatedBy}
    NodeType: MemberAccess
    Type: {Name = "String" FullName = "System.String"}

Hey I'm rather new to these could someone explain the significance or prehaps give a link to some useful information on lambda expressions?

I've been trying to learn more about using Lamba expression trees and so I created a simple example. Here is the code, this works in LINQPad if pasted in as a C# program. void Main() { IEnumerable<User> list = GetUsers().Where(NameContains("a")); list.Dump("Users"); } // Methods public… >>> More
