Question

Is is possible to scan a function provided as a lamba expression to figure out the nature of the function at runtime?

Example:

class Program
{
    static void Main(string[] args)
    {
        Examples example = new Examples(x => x ^ 2 + 2);
    }
}

public class Examples
{
    public Examples(Func<dynamic, dynamic> func)
    {
        // How can I scan "func" here to figure out that it is defined as "x => x ^ 2 + 2" instead of, say, as "x => Math.Exp(x)"?
    }
}

Answer 1

You need to use expression trees, like this:

public Examples(Expression<Func<dynamic, dynamic>> func) {
    ...
}
