c# - linq to xml initializing array -

-

i have 2 classes - cd , track i'm trying read xml file using linq.

public cd(string t, string a, string cat, datetime rls, track[] tr)
public track(string t, int l)

the xml looks this.

 <media>   <cd>     <artist>ozzy osbourne</artist>     <album name="bark @ moon" type="metal" tracks="5" releasedate="1983-12-10">       <track length="300">bark @ moon</track>       <track length="235">you're no different</track>       <track length="567">now see (now don't)</track>       <track length="356">rock 'n' roll rebel</track>       <track length="120">centre of eternity</track>     </album>   </cd>   <cd>     <artist>journey</artist>     <album name="escape" type="rock" tracks="4" releasedate="1981-07-31">       <track length="300">don't stop believin'</track>       <track length="235">stone in love</track>       <track length="567">who's crying now</track>       <track length="356">keep on runnin'</track>     </album>   </cd> </media>

the code i'm trying use follows

 xelement xdoc = xelement.load("dbxml.xml");     var temp = cds in xdoc.descendants("cd")     select new cd(         cds.element("artist").value,         cds.element("album").attribute("name").value,         cds.element("album").attribute("type").value,         datetime.parse(cds.element("album").attribute("releasedate").value),         new track[] { // 1 track reads fine..             new track(cds.element("album").element("track").value,                int.parse(cds.element("album").element("track").attribute("length").value))                 }         );

the problem don't know how initialize array tracks read xml file. wrap whole query in .tolist(), use anonomyous type , foreach-it i'd know if there way in 1 run linq.

cds.elements("album").elements("song") returns ienumerable<xelement> collection , somehow should added array range , turned string , int, or affect. out there?

thanks!

this work:

xelement xdoc = xelement.load("test.xml"); var temp = cds in xdoc.descendants("cd")             select new cd(                 cds.element("artist").value,                 cds.element("album").attribute("name").value,                 cds.element("album").attribute("type").value,                 datetime.parse(cds.element("album").attribute("releasedate").value),                 cds.element("album").descendants("track").select(t => new track(t.value, int.parse(t.attribute("length").value))).toarray()                  );

easier read (imo) using properties: 

select new cd()     {         artist = cds.element("artist").value,         album = cds.element("album").attribute("name").value,         type = cds.element("album").attribute("type").value,         releasedate = datetime.parse(cds.element("album").attribute("releasedate").value),         tracks = cds.element("album")                     .descendants("track")                     .select(t => new track()                     {                       name = t.value,                       length = int.parse(t.attribute("length").value)                     }).toarray()     };

you should consider adding default constructor cd , track , exposing public properties or use named parameters - make linq statement more readable.

binding - How can you make the color of elements of a WPF DrawingImage dynamic? -

-
we have need make vector graphic images change color of elements within graphic @ runtime. seem setting colors based on either static or dynamic resource values wouldn't work. want have multiple versions of same graphic, each abilty set graphic elements (path, line, etc) different colors don't think dynamic resource approach work. leaves data binding seems right approach. update graphic use data binding expr instead of hard-coded brush color so: <drawingimage x:key="graphic1"> <drawingimage.drawing> <drawinggroup> <drawinggroup.children> <geometrydrawing geometry="f1 m 8.4073,23.9233l"> <geometrydrawing.pen> <pen linejoin="round" brush="{binding line1brush, mode=oneway}"/> </geometrydrawing.pen> </geometrydrawing> <geometrydrawing geometry="f1 m 3.6875,2.56251l"> <geometrydrawing....
