problem in converting a c++ bit of code to its c# counter part

hello all ,
i was asked to convert a c++ sourcecode into its c# counter part , but i have no idea how i should go about this particular snippet of code.
i would be very thankful if anyone assists me in this problem .
the c++ snippet of code is this :

Code:

 typedef double (*FunctionCallback)(double sol[D]);
FunctionCallback function = &sphere;

and this is sphere function , already converted to c#

Code:

static double sphere(double[] sol)
{
    int j;
    double top=0;
    for(j=0;j<sol.Length;j++)
    {
        top=top+sol[j]*sol[j];
    }
    return top;
}

Thankyou in advance.

Look into delegates:

Code:

delegate double FunctionCallback(double[] sol);
FunctionCallback callBack = sphere;
