Question

I am trying to use a dll in a c# windows application. this dll is expecting one double[][] parameter( more than 10000 values) and another double[] parameter.

public static double[] CalcResults(double[][] Positions, double[] Values)

I am not quite sure how to declare this variable in the c# class.
Appreciate your help.

Answer 1

double[][] positions = new double[size1][];

Edit: Better yet, try this:

double[,] positions = new double[size1, size2];

Edit2: Doing Arrays – C# shows the difference between jagged arrays ([][]) and regular two-dimensional arrays ([,]).
