NET/Link return array from C++

I am having some problems returning an array back from C++.

I would expect {100.,100.,100} coming back in my example.
Can anyone explain what I do wrong?

void Test123(double x[], int size, double* result)
      for (long i = 0 ; i < size; i ++)
		*(result+i) = 100.;


In[1]:= Needs["NETLink`"];
TEST123 = DefineDLLFunction["ErrorFunctionA","mydll.dll",
"Void",{"double[]", "long", "out double"}];

input1=MakeNETObject[{1., 2., 3.}];
res=MakeNETObject[{0.0,0.0, 0.0}];

TEST123[input1, 3, res]
