Open file from resource as a stream?
Or just how to read resource text file line by line?

Check out StreamReader()

Re: How to?

If you mean a simply a file marked as an embedded resource, then the
following shows both stream and reader usage. For files in a resx, it is
harder; text files get handled as strings by default... I've never
bothered finding out if you can change this ;-p

Marc

using System;
using System.IO;
using System.Reflecti on;

class Program
{
static void Main()
{
// need to start at an assembly (and optionally, also a Type)
Assembly assembly = typeof(Program) .Assembly;

// what do we have access to?
foreach(string name in assembly.GetMan ifestResourceNa mes()) {
Console.WriteLi ne(name);
}
// watch for the default namespace!
const string FOO_NAME = "MyDefaultNames pace.foo.xml";

// open the stream-reader
using(StreamRea der reader = new StreamReader(
assembly.GetMan ifestResourceSt ream(FOO_NAME)) ) {

string line;
while ((line = reader.ReadLine ()) != null)
{
Console.WriteLi ne(line);
}
}
}
}

I cant get through ...
assembly.GetMan ifestResourceSt ream(FOO_NAME)
whatever I put into FOO_NAME it returna null as a stream

Re: How to?

Well, what does the first loop display? And are you sure it is an
embedded resource? If it is just "a resource on the file system" then
you can just use File.Open etc... "resource" is an overloaded term, so I
guessed at "embedded".

I mean a main sesource of VS2008 sollution.
Namespace_xxx.P roperties.Resou rces.
The first loop displays this as:

Alicja.SystemAl icja.Properties .Resources.reso urces

Re: How to?

That is the "resx" I was referring to... text contents have this
distressing tendency to jump into strings ;-(

You could look at ResourceManager .GetStream, but I've never managed to
get it working (meaning: I was happy to simply use an embedded resource
instead...)

by default the name of the assembly gets prefixed to the name of the
file

Re: How to?

ResourceManager returns that fila as a byte[]
not as Stream ... ech ...

To be pedantic, I think it uses the default namespace from the project,
not the assembly name. But the two should usually agree...

so.

How to "convert" byte[] into a stream or
just recreate file from byte[] chain?

If none of the other suggestions are working for you, you can always
create a MemoryStream from a byte[].

That's what I needed :-)
