Class Inside Structure
- by Knvn
Could some one please explain, What happens when a reference type is defined inside the value type.
I write the following code:
namespace ClassInsideStruct
{
class ClassInsideStruct
{
static void Main(string[] args)
{
ValueType ObjVal = new ValueType(10);
ObjVal.Display();
ValueType.ReferenceType ObjValRef = new ValueType.ReferenceType(10);
ObjValRef.Display();
Test(ObjVal, ObjValRef);
ObjVal.Display();
ObjValRef.Display();
Console.ReadKey();
}
private static void Test(ValueType v, ValueType.ReferenceType r)
{
v.SValue = 50;
r.RValue = 50;
}
}
struct ValueType
{
int StructNum;
ReferenceType ObjRef;
public ValueType(int i)
{
StructNum = i;
ObjRef = new ReferenceType(i);
}
public int SValue
{
get { return StructNum; }
set
{
StructNum = value;
ObjRef.RValue = value;
}
}
public void Display()
{
Console.WriteLine("ValueType: " + StructNum);
Console.Write("ReferenceType Inside ValueType Instance: ");
ObjRef.Display();
}
public class ReferenceType
{
int ClassNum;
public ReferenceType(int i)
{
ClassNum = i;
}
public void Display()
{
Console.WriteLine("Reference Type: " + ClassNum);
}
public int RValue
{
get { return ClassNum; }
set { ClassNum = value; }
}
}
}
}
Which outputs:
ValueType: 10
ReferenceType Inside ValueType Instance: Reference Type: 10
Reference Type: 10
ValueType: 10
ReferenceType Inside ValueType Instance: Reference Type: 50
Reference Type: 50
I'm curious to know, after calling the method Test(ObjVal, ObjValRef), how the values of ReferenceType is changed to 50 which resides inside the ValueType who's value is not changed?
