Thanks for your reply.
With out invoking C# code,  Can I directly write this function in power shell 
static int SumParameters(params int[] values){
int total = 0;
foreach (int value in values){
total += value;
return total;
And passing parameters 
SumParameters 1
SumParameters 1 2  
SumParameters 1 2 3
