Question

(for LISP hackers in short: I’m looking for the LISP-quote equivalent in C#)

I’m trying to write a meaningful ToString-method for a class which has a Func as member. Experiened API-users can set this member via setter-method like

myClassObject.SetFunction( (x) => x*x );

Now, when I use the ToString-method on the member it only returns

System.Func<double,double>

which is not very helpful. What would be helpful is

"(x) => x*X"

Is there any (preferable easy) way to do that?

Thanks for any help or comments.

Edit: corrected some typos

Answer 1

Expression<Func<double,double>> expr = x => x * x;
string s = expr.ToString(); // "x => (x * x)"
