returning multiple object types

[moorman12]

Hi,
I am still learning c# and I had a question regarding returning multiple variable from a function. I pass a point object to a function and I want to return an integer and another point from that function. Is this possible?

function returnTwoObjects(point a)
{
return point and an integer
}

tks

Create a class that contains your 2 types and pass that back. This is known as a bean (encapsulation)

public class PointInfo
{
public Point Location;
public int Count;
}


private PointInfo DoSomeWork(point a)
{
//blah blah return a PointInfo object
}

Creating a class is common but you also can return as many objects you want using ref or out.
Example:

void  returnTwoObjects(point a, ref point b, ref int myInt)
{
    b=...;
myInt =...;
}

How to call the function ?
point a=...;
point onePoint=...;
int oneInt =0;
returnTwoObjects(a,ref onePoint, ref oneInt);
//Now the values of onePoint and oneInt were modified by function call.

or

void  returnTwoObjects(point a, out point b, out int myInt)
{
    b=...;
myInt =...;
}

The ref and out keywords are treated differently at run-time, but they are treated the same at compile time.
The variables passed as an out arguments need not be initialized prior to being passed.
