HI I have installed umbraco 4.7

from the install pacakage I have taken the umbraco.dll 1.0.4090.38017 and referenced it in visual studio 2010 project,  I then wrote the follwiing code to loop through the Parent and its child nodes:

         Node CurNode = Node.GetCurrent();
         Nodes ChNodes = CurNode.Children;

         string text = null;

            foreach (Node doc in ChNodes)
            {
                if (doc.Children.Count > 1)
                {
                    text += doc.Name + "--";
                   
                }
            }
            Label1.Text = text;

when I compile the project in VS2010 I get the following error:

Error 1 The type 'umbraco.interfaces.INode' is defined in an assembly that is not referenced. You must add a reference to assembly 'interfaces, Version=1.0.4085.20549, Culture=neutral, PublicKeyToken=null'. C:\Software Development\trunk\UserControls\DocumentList.ascx.cs 57 13 

How do I get rid of this error

Basically I want to read the document properties in csharp code and write it to format to diplay

you help is greatly appreciated

Kind Regards

Praveen
