Facing issues while initializing list

Question

I am trying to initialize a list of type Movie in class other than Movie while both the classes are in the same namespace. Code is mentioned underneath:

namespace MovieListCaseStudy
{
    class Movie
    {
        private int id;

        public int Id
        {
            get { return id; }
            set { id = value; }
        }
        private string name;

        public string Name
        {
            get { return name; }
            set { name = value; }
        }
        private float duration;

        public float Duration
        {
            get { return duration; }
            set { duration = value; }
        }
        private float price;

        public float Price
        {
            get { return price; }
            set { price = value; }
        }
    }
}

******

namespace MovieListCaseStudy
{
    class BusinessLogic
    {
        List<Movie> movielist = new List<Movie>();
        {
            {Id=1, Name="pk", Duration=2, Price=200}

        };
    }
}

the problem is that Id, Name etc. attributes are not being identified in the BusinessLogic class. Kindly help.

Side note: durations should by public TimeSpan Duration {get;set;} and price (as all money related values) should be public decimal Price {get;set;}. — Alexei Levenkov

You're missing new Movie():

List<Movie> movielist = new List<Movie>()
{
    new Movie() { Id=1, Name="pk", Duration=2, Price=200 }
};

Remove the trailing semi colon, and as per @Marcin, construct with new Movie(). Also note that default constructor parenths () are optional with initializers:

class BusinessLogic
{
    List<Movie> movielist = new List<Movie>
    {
        new Movie {Id=1, Name="pk", Duration=2, Price=200}
    };
}

As an aside, another shorthand is possible with Array initialization, although in this case it would require an additional .ToList() conversion which would be less efficient in this case:

class BusinessLogic
{
    List<Movie> movielist = new [] // No type needed, will be inferred
    {
        new Movie {Id=1, Name="pk", Duration=2, Price=200}
    }
    .ToList();
}
