Sharing methods between multiple controllers C# MVC4

I have the same method I call in six controllers. Right now I copy and paste between each of the controllers. All the controllers are in the same namespace. The method returns a bool based on the passed id. For example:

public bool CheckSubmission(int id =0)
{
    Get Records from DB with criteria
    If Record available return true
    else return false
}

I have been away from C++ C# for awhile and can't find how to write these once. I know in Rails I can put the shared functions in ApplicationController. I have seen several Questions on SO about this but not a clear example, they are more along the lines read up on OOP. Any help would be appreciated as I get back into this.

Create a ControllerBase class that inherits from Controller, place this method in it.

Have your controllers inherit from your base controller - they will get this implementation to use.

public class ControllerBase : Controller
{
  public bool CheckSubmission(int id = 0)
  {
    Get Records from DB with criteria
    If Record available return true
    else return false
  }
}

public class SomethingController : ControllerBase
{
    // Can use CheckSubmission in here
}
