Print out Linq Expression Tree Hierarchy

The dynamic language runtime (DLR) has some pretty cool code for Expression's, including some very nice code to print out Expression trees which I want to use so that:

int a = 1;
int b = 2;
Expression<Func<int, int>> expression = (c) => a + (b * c)
expression.Evaluate(5, stringBuilder)

Outputs:

(5) => a + (b * c) = 11 Where
     a = 1
     b * c = 10 Where
          b = 2
          c = 5

I found some code on the net to do this but found that it only works if the expressiontakes in no arguments.

I then discovered the DLR implementation of a similar method. However the DLR has its own custom implementations of the Expression class and many other standard C# types so I got a little confused. Anyone know how I can implement the above?
