使用接口添加私有设置器

Question

I have an Interface that has only one property like below

public interface IExtendable
{
      Hashtable ExtendedProperties { get; set;}
}

I want setter to be private but it doesnt allow because its coming from an Interface and everyhing should be public in it as I know.

So what can be the best practice to allowing private setter ?

• Dont use Interface in this scenario or what ?

Thanks in advance,

Answer 1

You can not add a private setter to an interface. If you want to have a private setter, then your interface will need to look like this:

public interface IExtendable 
{       
     Hashtable ExtendedProperties { get; } 
} 

And in the implementation of the interface you can add your private setter.

Answer 2

private interface IExtendable
{
    Hashtable ExtendedProperties { get; }
}

private class Extendable: IExtendable
{
    Hashtable ExtendedProperties { get; private set; }
}
