I need to write a program, that reads all string resources from dll and insert them into some table. I have the method, that reads resources:
private static
There is no way of doing that. Have a look to the resource section of you assembly through Reflector, for instance. Your text file is saved as String. There is no difference between String value and Text File value.
Binary files, however, won't be a problem, as for binary file types you'll have byte[] as value and not string.
