Question

basically I want to do this:

Func<string> f =  ()=> MyMethodName();

only having a string name of a method, i.e.:

 Func<string> f =  "MyMethodName";

Can this be done? Any problems, caveats? Can Reflection help? Can I first check if a method exist?

You don’t need a lambda expression at all here. You can use Delegate.CreateDelegate:

MethodInfo method = GetType().GetMethod(methodName);
Func<string> func = (Func<string>) Delegate.CreateDelegate(typeof(Func<string>),
                                                           obj, method);

That way you avoid a level of indirection, and you also do the reflection part once instead of on every invocation.
