c# - Determine Local Uri (Assembly.GetEntryAssembly() returns null) -

i have project-folder called testa, folder in called testb , in 1 folder name testc. in testc image (image.png) , want know how uri.

i need call function , give uri function

i tried many things like:

class.function(new uri("pack://application:,,,/testb/testc/image.png"));

but exception:

assembly.getentryassembly() returns null.

i pretty sure, part isn´t correct: "pack://application:,,,/testb/testc/image.png"

thanks suggestions :)
