Accessing functions in the same module via reflection
f#classes.net

Suppose I wanted to access a named function in the same module as another function.

That is, a function that takes a MethodInfo and a string, and returns the corresponding named MethodInfo, i.e., something like:

1
2
3

let getSomeOtherMethod (firstMethod: MethodInfo) (otherMethodName: string) =
    firstMethod.Module.GetMethods()
    |> Array.find (fun m -> m.Name = otherMethodName)

When I run the above code, the result of GetMethods() is an empty array, when the module is clearly nonempty.

Are F# modules even the same as .net modules? I read somewhere that they were classes instead, is that the case? Wandering around the original MethodInfo in VS2008 leaves me none the wiser...

Thanks in adv,

Mat

Hi,
the Module property refers to a .NET concept and not to the F# concept, so this may be the firt problem. Instead of using Module, I'd try using DeclaringType, which should give you a .NET class - but that's how F# modules are compiled.

The next thing is that you may need to specify BindingFlags for the GetMethods call. I think you'll need BindingFlags.Static ||| BindingFlags.Public - the first one specifies that it should look only for static methods (which is a .NET representation of F# functions) and the first one specifies that we're looking only for public members.

That's done it, and thanks a lot Tomas (again)! Much appreciated.
