How to pass array in C#

Question

I have a prototype:

 int[] medianFileter(int[] data);

and an array

 int[] intVal = new int[5];

How can I pass the intVal to the prototype in C#?

Answer 1

Um, you just call it (assuming you've got a real implementation to call):

int[] result = medianFileter(intVal);

Note that any changes made to the array within the method will show up in intVal: you're not passing each of the integers individually, but a reference to the whole array.

(There could be some trickiness here due to your use of the word "prototype" - it's not standard C# terminology, so I'm not exactly sure what you mean. If you could clarify the question, that would help.)

On a side note, method names in .NET are usually Pascal-cased, so this should probably be:

int[] result = ApplyMedianFilter(intVal);

• rahul: +1 for 'not passing each of the integers individually, but a reference to the whole array'

Answer 2

It's either I don't see some obvious weirdness here, or it's just usual function invocation:

int[] medianFiltered = medialFileter(intVal);

Answer 3

This is what you would do,

medianFileter(intVal);

Answer 4

What's the problem with:

medianFileter(intVal);

?
