- by Greg
Hi,
I have:
Main Program Class - uses Library A
Library A - has partial classes which mix in methods from Library B
Library B - mix in methods & interfaces
Why would I need a using statement to LibaryB just to get their extension methods working in the main class? That is given that it's Library B that defines the classes that will be extended.
EDIT - Except from code
// *** PROGRAM ***
using TopologyDAL;
using Topology; // *** THIS WAS NEEDED TO GET EXTN METHODS APPEARING ***
class Program
{
static void Main(string[] args)
{
var context = new Model1Container();
Node myNode; // ** trying to get myNode mixin methods to appear seems to need using line to point to Library B ***
}
}
// ** LIBRARY A
namespace TopologyDAL
{
public partial class Node
{
// Auto generated from EF
}
public partial class Node : INode<int> // to add extension methods from Library B
{
public int Key
}
}
// ** LIBRARY B
namespace ToplogyLibrary
{
public static class NodeExtns
{
public static void FromNodeMixin<T>(this INode<T> node) {
// XXXX
}
}
public interface INode<T>
{
// Properties
T Key { get; }
// Methods
}
}
