Calling TreeStore.AppendValues with array of values

Hello,

I am attempting to  call TreeStore.AppendValues with an array containing the values. However, AppendValues seems to have two conflicting definitions:

AppendValues(params object[] values)
and
AppendValues(Array values)

When I attempt to pass an array of strings for the values, the first element of the passed array gets populated for each value. I believe that even though I am passing an array, it is only taking the first value of the array because it thinks its still a variable argument call with only one variable argument. I attempted to use Type.Invoke on the method, specifying the arguments as just typeof(Array), however it still did the same thing.

Any ideas how I can overcome this?
