Getting An Array Result From A C# Method

Question

I am trying to write some code to return an array in C#, but don't know the proper syntax. I think my method is set up correctly, but to set an array to the result of the method is what I'm having difficulty with.

Method Declaration:

double[,] function(double variable)
{
...
code
...

return array
}

Answer 1

Array is double[]. double[,] is a two dimensional array (matrix).

Answer 2

public static ANameOfSomeClass
{
    public static double[] SingleDoubleArraryMethodName(double parameterValue)
    {
        double[] values = new double[3];

        values[0] = 1.0;
        values[2] = 1.5;
        values[2] = 1.75;


        return values;
    }

    public static double[,] MultDimDoubleArraryMethodName(double parameterValue)
    {
        double[,] values = new double[2,2];

        values[0,0] = 0.0;
        values[0,1] = 1.0;
        values[1,0] = 2.0;
        values[1,1] = 2.5;

        return values;
    }
}

You could call it like

double[] results = ANameOfSomeClass.SingleDoubleArraryMethodName(1.2);

If you remove the keyword static it becoms

ANameOfSomeClass yourObj = new ANameOfSomeClass();

double[] results = yourObj .SingleDoubleArraryMethodName(1.2);

Answer 3

Here is an example of how to create the two dimensional array, put some values in it, and return it:

double[,] function(double variable) {
  double[,] result = new double[2,2];
  result[0,0] = 1.0;
  result[0,1] = 2.0;
  result[1,0] = 3.0;
  result[1,1] = 4.0;
  return result;
}

If it is a one dimentional array that you want (the question is a bit unclear about that):

double[] function(double variable) {
  double[] result = new double[3];
  result[0] = 1.0;
  result[1] = 2.0;
  result[2] = 3.0;
  return result;
}

Answer 4

Guffa's answer illustrates how to create and populate a two-dimensional array (which it looks like is what you want to do).

To set a variable to the return value of this method, you would do this (supposing the method's name were MyMethod):

double myVariable = 12.34;
double[,] myArray = MyMethod(myVariable);
