C# List of arrays to array of arrays

Question

I am new to C#. I am writing a program in which a list changes size depending on user input. The list is of GPS coordinates so it is

List<double[]> coordinates= new List<double[]>();

However I have a function that needs the GPS coordinates in double[][] format, an array of arrays. It seems like this would be very straightforward because it seems like a list of arrays is already an array of arrays. However, the most logical thing I can think to do fails:

double[][]test = new double[][]{};

test = coordinates.ToArray;

with "Cannot convert method group 'ToArray' to non-delegate type 'double[][]'. Did you intend to invoke the method?"

Not sure what that means or how to fix. Any advice is appreciated.

You need parenthesis after ToArray. Thats the first problem. It should be ToArray() — Icemanind

To call a method in C#, you need to use parentheses, like this: test = coordinates.ToArray();

You forgot the parenthesis:

double[][]test = coordinates.ToArray();
