Accessing Resources in a C# WPF Application (Same Assembly) -

(before jump nitty-gritty, want set context: i'm trying load wpf frame contents of .html file i'm including in project resource.)

i create new wpf application; add new folder called 'foofiles' project, , add couple of files (page1.foo , page2.foo) folder.

for each newly added .foo file, right-click on it, go "properties," , set build action 'resource,' , copy output directory "copy always."

i want able access files both in xaml:

<frame x:name="bar" source="/foofiles/page1.foo"/> 

and in procedural code:

private void somefunc() {     bar.source = new uri("/foofiles/page1.foo"); } 

but can't figure out why doesn't work -- "format of uri not determined."

in code-behind, tried doing this:

private void somefunc() {     bar.source = new uri("pack://application:,,,/foofiles/page1.foo"); } 

which didn't throw exception, main window crashed.

in thinking, if add file of type project, , if mark "resource" in "build action," should able use file per examples above. also, use file this:

private void someotherfunc() {     system.io.streamreader reader = new system.io.streamreader("/foofiles/page1.foo");     string bar = reader.readtoend(); } 

any appreciated... in advance!

try adding component-part pack uri this

pack://application:,,,/assemblyname;component/resourcename 

where assemblyname name of assembly. case, following statement should work:

bar.source = new uri("pack://application:,,,/assemblyname;component/foofiles/page1.foo"); 

more practically, try relative pack uri notation:

bar.source = new uri("assemblyname;component/foofiles/page1.foo", urikind.relative));  

for stream reading resources use

var streamresourceinfo = application.getresourcestream(uri); using (var stream = streamresourceinfo.stream) {    // fancy stuff stream }
