access different item types from anonymous array

Question

A function returns an object, with an object member filled with an anonymous array of items; how do I get back the individual items?

the object that is returned from a function:

public class FunctionCallResult
{
   ...blah blah members...
    public object ResultObject { get; set; }
}

The function:

FunctionCallResult SomeCrazyFunction(string irrelevant_param1, int some_other_irrelevant_param2)
{
    ... some heavy duty code that raises eyebrows ...
    return new FunctionCallResult{ new object[] { SomeCrazyClassX, AnotherCraxyClassY } };
}

An example call of function:

var myresult = SomeCrazyFunction( "I am the walrus", 42);

But now, how do I get back the individual objects, which are of different classes?

// can't do this... can't index type of object
SomeCrazyClassXType classX = myresult.ResultObject[0];
AnotherCraxyClassYType classY = myresult.ResultObject[1];

So...how can I get these different class types out of the result returned?

Answer 1

If you "know" ResultObject is an object[] at runtime and the number of items in it and you know their types, you could cast them to SomeCrazyClassXType and AnotherCraxyClassYType after casting ResultObject to an object[] from object .

So:

var resultObjectAsAnObjectArray = (object[])myresult.ResultObject;
var classX = (SomeCrazyClassXType)(resultObjectAsAnObjectArray[0]);
var classY = (AnotherCraxyClassYType)(resultObjectAsAnObjectArray[1]);

I'd have to see more code/what you're actually doing to give a better recommendation.
