Convert double[] to System.array c#

I'm using a visual basic library and one of the methods I'm using calls for a System.Array to be passed into it. I've tried using "double[]" and "Object[]" when declaring my array however those will not pass. I'm not sure how to convert/declare a "System.Array". 

Object[] filledVals = new Object[9];                   
xyz.getDoubleArray("NumVoids", out filledVals); //where .getDoubleArray(string, System.Array)

Simply declare it as System.Array:

Array filledVals;
xyz.getDoubleArray("NumVoids", out filledVals);

Since it is an out parameter, you don't need to initialize it as it must be initialized by getDoubleArray.

To convert it to a double[] you can use this:

double[] result = filledVals.OfType<double>().ToArray();

You can use LINQ: 

System.Array result;              
xyz.getDoubleArray("NumVoids", out result);
var filledVals = result.OfType<double>().ToArray();
