Generic Property in C# [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<String> name; 

a pre-defined get and set will be performed on the string value.

How can that be done?

Thanks!

You can make a generic class like this:

public class MyProp<T> {     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<T> value)     {         return value.Value;     }      public static implicit operator MyProp<T>(T value)     {         return new MyProp<T> { Value = value };     } } 

...then use it in a class like so:

class SomeClass {     public MyProp<int> 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;
