error when using source code for treeview

[sasire18]

hi From the code project i downloaded a source code and used in my project and got the following error: 1.The best overloaded method match for 'Microsoft.Web.UI.WebControls.TreeNodeCollection.Add(Microsoft.Web.UI.WebControls.TreeNode)' has some invalid arguments

nodes.Add( Node( p, p.Substring( path.Length ), "file" ) )
nodes.Add(Node("",p.Substring( path.Length + 1), "folder" ) );

2.Argument '1': cannot convert from 'Test.WebForm7' to 'Microsoft.Web.UI.WebControls.TreeNode' it comes near

n.Text = nodeText.ToString();

		**return n;**

It is from TreeView in a customized tool I am unable to understand what went wrong thanks in advance sasi

What is the type of p parameter? << >>

used for loop where p is string for directories here is the full code

// recursive method to load all folders and files into tree
private void GetFolders( string path, TreeNodeCollection nodes )
{
// add nodes for all directories (folders)
string[] dirs = Directory.GetDirectories( path );
foreach( string p in dirs )
{
string dp = p.Substring( path.Length );
nodes.Add(Node("",p.Substring( path.Length + 1), "folder" ) );
}

		// add nodes for all files in this directory (folder)
		string\[\] files = Directory.GetFiles( path, "\*.\*" );
		foreach( string p in files )
		{
			nodes.Add( Node( p, p.Substring( path.Length ), "file" ) );
		}			

		// add all subdirectories for each directory (recursive)
		for( int i = 0; i < nodes.Count; i++ )
		{
			if ( nodes\[ i \].Type == "folder" )
			{
				GetFolders( dirs\[ i \] + "\\\\", nodes\[i \].Nodes );
			}
		}
