Generic Property in C

Question

Possible Duplicate    Making a generic property       I m not quite sure how to do that  but what I would like to do is to create a special type of property that will perform specific tasks at the get and set  and will be defined on generic type  For example  when writing this   MyProp lt String gt  name    a pre-defined get and set will be performed on the string value   How can that be done   Thanks

You just declare the property the normal way using a generic type:

public MyType<string> PropertyName { get; set; }

If you want to call predefined methods to do something in the get or set, implement the property getter/setter to call those methods.

You cannot  alter  the property syntax this way  What you can do is this   class Foo       string MyProperty   get  set        auto-property with inaccessible backing field     and a generic version would look like this   class Foo lt T gt        T MyProperty   get  set

You would need to create a generic class named MyProp   Then  you will need to add implicit or explicit cast operators so you can get and set the value as if it were the type specified in the generic type parameter   These cast operators can do the extra work that you need

Okay  I ll bite  You want something like this  If you declare a  property  like this   Update  I m now pretty sure that Fredrik M  rk answered your question and gave a solution  I m not really happy with the idea  but it seems to answer exactly what I understood from your question   public class PropertyFoo     public MyProp lt String gt  Name      this ends up as  public class PropertyFoo     public string Name       get      do predefined stuff here          set     other predefined stuff here              No  Not possible and not a property  really  Look for template snippet support in your IDE

You can make a generic class like this   public class MyProp lt T gt        private T  value       public T Value               get                          insert desired logic here             return  value                    set                          insert desired logic here              value   value                       public static implicit operator T MyProp lt T gt  value                return value Value             public static implicit operator MyProp lt T gt  T value                return new MyProp lt T gt    Value   value                 then use it in a class like so   class SomeClass       public MyProp lt int gt  SomeProperty   get  set        The implicit operators means that you do not need to explicitly set or get the Value property of MyProp  but can write code to access the value in a more  natural  way   SomeClass instance   new SomeClass    instance SomeProperty   32  int someInt   instance SomeProperty
