Can somehow a method from base class return child class?

Question

I\'ll give an example, so you can better understand what i mean:

public class Base
{
      public Base Common()
      {
          return this;
      }
}

pub         


        

Answer 1

You could make Base generic and use the Curiously Repeating Template Pattern:

public class Base where T : Base
{
      public T Common()
      {
          return (T)this;
      }
}

public class XBase : Base
{
     public XBase XMethod()
     {
          return this;
     }
}

Then you can just use:

var a = new XBase().Common().XMethod();
