Hiding interface methods in Intellisense in Visual Studio

I have an interface and it has many methods. I should not see these methods in Intellisense in implementing classes. How can I do that?

You will need to implement them explicitly.

If your interface is:

interface IFoo{
  void DoSomething();
}

then you can implement that explicitly in a class like below:

class Foo : IFoo {
  void IFoo.DoSomething();
}

That being said, you probably wonder consider why you want to do this. An interface is often used to define a contract of what an object of a given type is capable of. Wanting to hide it can be a smell of something go astray in the design process. Of course there's also many valid cases for the use of explicit implementation. E.g. Dictionary has explicit implementations for quite a few of the methods from IEnumerable>. but the hiding should be more the exception than the rule.

If you declare the variable/member of the interface type the methods will show, if you declare the member/variable of the concrete type they will not show. Since you should generally prefere interfaces to concrete classes this again is a hint that you might wanna look at the reason for wanting to hide the methods declared by the interface

You can use EditorBrowsableAttribute on your methods.

EditorBrowsableAttribute Specifies that a property or method is viewable in an editor. EditorBrowsableAttribute is a hint to a designer indicating whether a property or method is to be displayed. You can use this type in a visual designer or text editor to determine what is visible to the user. For example, the IntelliSense engine in Visual Studio uses this attribute to determine whether to show a property or method.

Something like

  

   [EditorBrowsable(EditorBrowsableState.Never)]
   public void GetId()
   {
   }
