Inheritance

[BRawn]

I'm having a bit of an issue inheriting from a class. I'm taking code from an old VB.NET app and writing it in C#. I have a public class which only consists of 2 fields, a constructor and 2 properties.

I need to inherit a generic list object which isn't a problem, but my environment doesn't see the class from which it must inherit.

Class: MyClass

            public class MyClass
    {

        #region /// FIELDS ///

        string columnName;
        string format;

        #endregion

        #region /// CONSTRUCTORS ///

        public MyClass()
        {
            columnName = "";
            format = "";
        }

        public MyClass(string fieldName, string formatString)
        {
            columnName = fieldName;
            format = formatString;
        }

        #endregion

        #region /// PROPERTIES ///

        public string ColumnName
        { get; set; }

        public string Format
        { get; set; }

        #endregion

    }

When I try to inherit MyClass from my Collection object, I can't...
What I want to do is:

public class Collections : List<MyClass>

In VB.NET, the code looks like this:

Public Class Collections
    Inherits List(Of MyClass)

    Public Sub New()
        MyBase.New()
    End Sub

End Class

How can I achieve the same result in C#?

Nevermind, found the problem.
The classes are in different folders in the solution (not solution folders, standard folders) and each folder is seen as on object. I had to reference the folder that my MyClass was in before the Collections class would recognize it
