Array of function pointers in C#

Question

There is a set of methods like:

  Foo(int, float, params objects[])
  Goo(int, params objects[])
  Too()

each taking different number of & type of parameters (so are return values).

I read an integer (an index) from a database. The integer corresponds to one of the above method (1 for Foo, 2 for Goo and 3 for Too).

How do I store above methods (as delegates) in a collection so that I can call appropriate method by indexing into the collection using the integer read from db as index.

Answer 1

You could just use a Delegate[] - when you read the integer, you'll then need to cast the relevant array value to an Action<int, float, object[]>, an Action<int, object[]> or an Action before you call it though.
