How to call the method from a MethodCallExpression in c#

Question

I have a method call expression and try to invoke the method. I figured out a way, but I have problems in retrieving the parameter values since not every argument is describ

Answer 1

I would try this to return the object:

private static object _getValue(MethodCallExpression expression)
{
    var objectMember = Expression.Convert(expression, typeof(object));

    var getterLambda = Expression.Lambda>(objectMember);

    var getter = getterLambda.Compile();

    return getter();
}

It is much faster can calling the following:

LambdaExpression l = Expression.Lambda(Expression.Convert(element, element.Type));
return l.Compile().DynamicInvoke();
