Hi, Look at the copy constructor sample : using System; namespace
CopyConstructorSample
{
/// <summary>
/// Summary description for CopyConstructor.
/// </summary>
public class CopyConstructor
{
public int var1;
public CopyConstructor()
{} public CopyConstructor(CopyConstructor obj)
{
var1 = obj.var1;
}
}
}
However consider the following points before using them : 1. Favor Clone and
Deserialize over copy constructors unless you�re really aiming at value semantics.
They will be more consistent with the way serialization works and the existing
patterns. 2. It�s easy to implement a Clone method in terms of a copy
constructor and impossible to do the opposite, but� 3. Object.MemberwiseClone
supports writing Clone methods and not copy constructors. 4. Like many things in
the pre-generics flavor of C#, the �object� return type of ICloneable.Clone is
unfortunate, but just deal with it. 5. Don�t overlook using serialization if you
just need some kind of copy operation. --Nitin
