c# - WPF - Good Way to take a list to a Tree -

i have list looks this:

 base/level1/item1 base/level1/item2 base/level1/sub1/item1 base/level2/item1 base/level3/sub1/item1 

i easy way put listview. (ie similar this)

 base   |   +->level1   |    |   |    +=item1   |    +=item2   |    |   |    +->sub1   |        |   |        +=item1   |   +->level2   |    |   |    +=item1    |   +->level3        |        +->sub1            |            +=item1 

is there established way make kind of conversion or need roll own parser?

(in case may relevant real items in code tfs iteration paths.)

this take list of strings , turn tree suitable viewing treeview described:

public ilist buildtree(ienumerable<string> strings) {   return     s in strings     let split = s.split("/")     group s s.split("/")[0] g  // group first component (before /)     select new     {       name = g.key,       children = buildtree(            // recursively build children         s in grp         s.length > g.key.length+1         select s.substring(g.key.length+1)) // select remaining components     }; } 

this return tree of anonymous types, each containing name property , children property. can bound directly treeview specifying hierarchicaldatatemplate itemssource="{binding children}" , content consisting of <textblock text="{binding name}"> or similar.

alternatively define tree node class in code if want additional members or semantics. example, given node class:

public class node  {   public string name { get; set; }    public list<node> children { get; set; }  } 

your buildtree function different:

public list<node> buildtree(ienumerable<string> strings) {   return (     s in strings     let split = s.split("/")     group s s.split("/")[0] g  // group first component (before /)     select new node     {       value = g.key,       children = buildtree(            // recursively build children         s in grp         s.length > g.key.length+1         select s.substring(g.key.length+1)) // select remaining components     }     ).tolist(); } 

again can bound directly using hierarchicaldatatemplate. use first solution (anonymous types) unless want special tree nodes.
