How to pass a variable with CSharpCodeProvider?

I need to create an EXE file with my application, I can pass strings with manipulating the string format but I cannot pass the other variables that I need to ex:byte array, here is my code if this helps:
using Microsoft.CSharp;
using System;
using System.CodeDom.Compiler;
using System.Windows;
namespace ACompiler.CompWorker
{
class CompilerWorker
{
public static byte[] testarray = SomeClass.SomeArray;
public static string Key = "Testkey12";
public static void Compile()
{
CSharpCodeProvider CompileProvider = new CSharpCodeProvider();
CompilerParameters CompileProviderParameters = new CompilerParameters(new[] { "mscorlib.dll", "System.Core.dll" }, AppDomain.CurrentDomain.BaseDirectory + "Compiled.exe", true);
CompileProviderParameters.GenerateExecutable = true;
string test= #"using System;
namespace Tests
{
class Program
{
static void Main(string[] args)
{
byte[] Content = " + testarray + #";
string Key = """ + Key + #""";
Console.WriteLine(""Key: "" + EKey);
Console.WriteLine(Content);
Console.ReadLine();
}
}
}
";
var Result = CompileProvider.CompileAssemblyFromSource(CompileProviderParameters, test);
}
}
}
Basically I want to move the "testarray" into the compiled app, I hope someone can point me to the right direction!

The trick is to "serialize" the data back in to code the compiler can compile. Try this:
var arrayCode = "new byte[] { " + string.Join(", ", testarray) + " }";
string test = #"using System;
namespace Tests
{
class Program
{
static void Main(string[] args)
{
byte[] Content = " + arrayCode + #";
string Key = """ + Key + #""";
Console.WriteLine(""Key: "" + EKey);
foreach(byte b in Content)
{
Console.WriteLine(b.ToString());
}
Console.ReadLine();
}
}
}
";
Keep in mind, you can't do Console.WriteLine on a byte array object and have it spit out each item. You will have to iterate over the items to print them out. I updated your code to do it the proper way.

C# System.IO.IOException

FileReport fileReport = virusTotal.GetFileReport(fileInfo);
bool hasFileBeenScannedBefore = fileReport.ResponseCode == ReportResponseCode.Present;

{

}
}
}
This code run some time (arround 15secs) but then program crashs.
The error is
System.IO.IOException, process can't access to file C:\hiberfil.sys.

Do you have any idea how to solve it?

C# Unhandled Exception: Cannot Read from a Closed Textreader

So I'm trying to have my program read from a text file and display what is on that text file inside the command prompt, like so...
But then the program can read only one line of the file, and then throws this error exception
I've tried going over the lines of my three .cs files they complain about. I tried debugging and editing my code, but the more I do it, the worse it gets, so I'm very lost and confused and I honestly don't know what to fix at this point.
These are the lines of codes they complain about, and right below them are the actual code files.

This is my first time doing C# and I'm very new to this. I appreciate your grand help.

You are closing your reader on first iteration of your while loop.

Using Office.Interop, certain Powerpoint filenames won't convert

I have a program that converts .ppt or pptx files to png's using C# and the Microsoft.Office.Interop stuff.
It works most of the time, but under certain circumstances, it seems to fail on specific filenames for some nondescript reason.
HRESULT E_FAIL at ... Presentations.Open
It'll fail on CT_Stress_Test - Copy (16).pptx and CT_Stress_Test - Copy (11).pptx It works for (2) thru (19), but fails on only these two. My question is why?
If I were to make copies of these copies, or rename them to something else, it'll convert just fine, so I think it might have something to do with the filename.
I have the same conversion program running on my server and my local machine. My local machine (Win 7) converts the problem files just file. It's only on the server (Win 2008) that I have problems with these two filenames.
EDIT: I've found another number that doesn't work: (38)
EDIT: I formatted the strings with Path functions, and that didn't help.
EDIT: I was able to fix it by trimming all the spaces from the file names. I still want to know why this happens, though.

First up is a warning from Microsoft in this KB article here. Money quote is:
Microsoft does not currently recommend, and does not support,
Automation of Microsoft Office applications from any unattended,
non-interactive client application or component (including ASP,
ASP.NET, DCOM, and NT Services), because Office may exhibit unstable
behaviour and/or deadlock when Office is run in this environment.
Next question is why not use OpenXML for this? Here's a simple sample to get you started which counts the number of slides in a deck.
using System;

using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Xml;
namespace OpenXmlDemo
{
class PptOpenXmlDemo
{
public int PptGetSlideCount(string fileName)
{
// Return the number of slides in a PowerPoint document.
const string documentRelationshipType = "http://schemas.openxmlformats.org/officeDocument/2006/relationships/officeDocument";
const string presentationmlNamespace = "http://schemas.openxmlformats.org/presentationml/2006/main";
int returnValue = 0;
using (Package pptPackage = Package.Open(fileName, FileMode.Open, FileAccess.Read))
{
// Get the main document part (presentation.xml).
foreach (System.IO.Packaging.PackageRelationship relationship in pptPackage.GetRelationshipsByType(documentRelationshipType))
{
// There should be only a single relationship that refers to the document.
Uri documentUri = PackUriHelper.ResolvePartUri(new Uri("/", UriKind.Relative), relationship.TargetUri);
PackagePart documentPart = pptPackage.GetPart(documentUri);
// Get the slide part from the package.
if (documentPart != null)
{
XmlDocument doc = new XmlDocument();
doc.Load(documentPart.GetStream());
// Manage namespaces to perform XPath queries.
XmlNamespaceManager nsManager = new XmlNamespaceManager(doc.NameTable);
nsManager.AddNamespace("p", presentationmlNamespace);
// Retrieve the list of slide references from the document.
XmlNodeList nodes = doc.SelectNodes("//p:sldId", nsManager);
if (nodes != null)
{
returnValue = nodes.Count;
}
}
// There is only one officeDocument part. Get out of the loop now.
break;
}
}
return returnValue;
}
}

I tried to add reference to dll, add it to project, changed Build Action to embedded resource, but nothing worked. Any help?

Let's call the assembly of your project MyAssembly.
Create a new folder at the root of your project in Visual Studio. Let's call it MyDlls.
Put your assembly you want to include in this folder and set their Build Action to Embedded Resource.
Then, in your code, add the following elements:
class Program
{
// ... Your code
[STAThread]
static void Main(string[] args)
{
AppDomain.CurrentDomain.AssemblyResolve += AssemblyResolve; // Called when the assembly hasn't been successfully resolved
// ... Your code
}
private Assembly AssemblyResolve(object sender, ResolveEventArgs args)
{
Assembly assembly = Assembly.GetExecutingAssembly();
string assemblyName = args.Name.Split(',')[0]; // Gets the assembly name to resolve.
using (Stream stream = assembly.GetManifestResourceStream("MyAssembly.MyDlls." + assemblyName + ".dll")) // Gets the assembly in the embedded resources
{
if (stream == null)
return null;
byte[] rawAssembly = new byte[stream.Length];
stream.Read(rawAssembly, 0, (int)stream.Length);
return Assembly.Load(rawAssembly);
}
}
}
