  • 0

In my C# code, I have constructed four arrays of data:

double[] values;
DateTime[] timestamps;
long[] qualities;
long[] reasons;

These arrays need to be passed to an external API. The API method call is somewhat indirect; its signature looks like invokeApiMethod(string apiMethodName, Object[] apiMethodParams).

In this case, the external API method call expects four arrays of the kind that I have already constructed.

If I construct the Object[] using the following code:

Object[] apiMethodParams = { values, timestamps, qualities, reasons };

Will this result in all four existing arrays being copied into a large contiguous block of new memory? Or will C# just pass an array of references to the existing arrays to the external API?

    The latter. It will be an array of four elements, each element of which is a reference. The values of values, timestamps etc are just references to arrays.

    Note that you may want to take a copy of some or all of the arrays if the external API modifies the array contents, and you want the original values – but that won’t happen automatically.
