Hi. Im a C# newbie, just want to ask how to implement the ICloneable.Clon e..
Dont know how it works, would really appreciate it if someone could show a
simple source sample of how to do this.. Thank you so much!

Hi. Im a C# newbie, just want to ask how to implement the
ICloneable.Clon e..
Dont know how it works, would really appreciate it if someone could show a
simple source sample of how to do this.. Thank you so much!

public class X : ICloneable
{
// a represents here whatever the internal state of the object is
private int a;

// you may want a private ctor specifically for this purpose
public X(int p) { a = p;}

// allows X x2 = x1.Clone();
// visible in intellisense
public X Clone() { return new X(a); }

// allows X x2 = (X)((ICloneable )x1).Clone();
// NOT visible in intellisense for an object of compile time type X
object ICloneable.Clon e()
{
return Clone();
}
}

This is an explicit implementation of the interface with a typesafe method
as well - I recommend this approach be used always as it is much more user
friendly than just just implementing the interface "normally":

public class X : ICloneable
{
private int a;

public X(int p) { a = p;}

// allows X x2 = (X)x1.Clone();
// visible in intellisense
public object Clone() { return new X(a); } }
