How to retrieve a specific object from a list in C# based on the value of a field

   
      I have an object call video(See video class below ) in my C# application.
      
      I have a list like    List<object> mylist = new List<object>();
      
      I have a while loop where objects are added to the list
      
      While{
      Video myvideo = new Video(id,path);
            mylist.add(myvideo)
            

      }
      
      I would like to include in the while loop code that checks if an object exsist based on ONLY the ID since the path may be different.
      If the ID exsist I would like to retrieve the path for that object.
      
      Can you show me code examples of the following:
      
      1. Check if object exsist with a particular ID.
      2. Get the Path value for that object based on the ID.
      3. Remove the object for that ID.
      
      
      
      
      class Video
    {

        private string id;
        private string Path;

        public Video(string id, string Path)
        {
            this.MyPath = Path;
            this.Myid = id;
        }


        public string Myid
        {
            get{return id;}
            set{ id = value;}
        }
        public string MyPath
        {
            get { return Path; }
            set { Path = value; }
        }


    }
}
