c++\cli using System::Linq::Expressions::Expression

Can some one show me an example of how to create the following expression, using System::Linq::Expressions::Expression in C++\CLI.


C# version

int UWI;
Borehole^ b;

boreholes = new Collection<Borehole^>(kingdom->Get<Borehole^>(b => b.UWI == UWI).ToList());

C++\CLI version

I want to convert the following C# expression (b => b.UWI == UWI) to

System::Linq::Expressions::Expression<System::Func<Borehole^, bool>^>^ _expression;

How should can I build expression object _expression into (b => b.UWI == UWI) and allocate object _expression?

You can use any obect for sample demo.
