I'm new to C# and .Net platforms. I have a problem.

I want to create a custom class. This class has Disposible method and implements the IDisposible interface. And I want to if everyone want to using my class and create instance he must to use using syntax.

Because I want to it

using (Person person = new Person()) 
{
    // Some code example
};

I don't want to use create a instance without using declarations

Person person = new Person () // I don't want it this method

Is it possible or not? (maybe a custom attribute, maybe .net attributes, maybe another method)

What do you? What advice would you give me about this job?

It's perfectly possible that you want to delay calling Dispose beyond a using statement:

void Func()
{
   var thingToDispose = new DisposableThing();
   DisposeMyThing(thingToDispose)
}

void DisposeMyThing(IDisposable disposable)
{
   disposable.Dispose();
}

Therefore you cannot do this with just implementing IDisposable.

I believe your original requirement is not possible.

I think there is one reason why this will never be supported in C#:

• Dependency injection

In other words: it must be supported that an instance can be created in a different scope than where it is used. It would already be impoosible to use factory methods like:

using var p = GetPerson(); // different scope
// ...
