[IronPython] How does IronPython resolve overloads?

[Nev Delap]

Hi there.

Can anyone tell me, or point me at a link that will tell me how IronPython chooses which overloaded method to call? In the example below the Open() method has a number of overloads...

  1. Open()
  2. Open(string)
  3. Open(string[])
  4. Open(delegate) // async versions with a delegate to call when the async open completes.
  5. Open(string, delegate)
  6. Open(string[], delegate)

In the example I want it to be calling #1, but it seems to be calling #4, and then failing to create a delegate out of the string parameter.

Any help will be greatly appreciated.
