I want to create a self-extracting executable in C#.
The requirement is that when I build my C# project, the output of the build should be a self-extracting EXE file which will contain all the files and folders of a predetermined path recursively.
When I run the EXE file generated by building the project, it then extracts all the files to a predetermined folder.
How can I achieve this in C#?
You can embed any number of files of arbitrary type into a C# executable, and emit them during runtime. Here is a good tutorial. This embedding approach is usually used to pack all DLLs your executable refers to into the executable itself (see e.g. this), but it is also appropriate to make a self-extracting executable.
Better use a setup like NSIS. It is easy to use and generates a single EXE file.

I'm planning to build my winform into a .exe file. I'm just wondering what to do with the XML files that my application needs?
I did some research and found out that I can add the XML files in the Resource folder before creating a .exe file.
Or I need to create a setup file? When the user runs the setup file, the XML files will be installed into their pc.Now I wonder which one is the best way to go for,
Note: XML files might get modified by the user.
If you want to ship the XML files as seperate to the .EXE then you can set the Copy to Output Directory to Copy if newer. (click on file and then go to properties).
OR if you want it as part of the .EXE I think you can change the Build Action to Embedded Resource.
I personally would create a Setup as per your edit and include the XML files. I usually just add everthing from the bin/release folder that is needed when I create a setup file.
You could either deploy the necessary files along with the executable in the same folder or embed them as resources (if they are read-only). If you need to modify them do not embed them as resources into the executable.
The correct way depends on how you intend to use the files. If the files always are deployed together with your application, the application never writes to them and they are never upgraded without upgrading the application, you can go with them embedded as resources.
If you need to update them separately from the application, you need to have them as physical files.
You don't necessarely need a installation package, unless you need to apply some logic during setup, such as updating the content of the setup based on user input or to check preconditions. The application can just be copied into place regardless of if you have embedded the files or not.
I am trying to write a small application, whose only purpose is to copy some folders and .cs source files into a user specified Directory, I can do it easy enough by simply having the application look for the files and folders in its own install directory then copy them to thier destination Directory, but I was wondering if its possible to Embed the Folders and Files into the Application, so that when you run the application it creates or copies the folders and files from the exe app directly to the install directory, rather than searching for them in the apps install directory then copying them over. Basically Im trying to only have a single exe file rather than having an exe file and a bunch of folders and files along side it.
Is this possible to do with just a Windows Form App without using an actual Installer Class?
Yes. Embed the files into the application executable as embedded resources. Then when your application runs, access the embedded files and write them to disk in the desired directory structure.
Here is an example of how to embed and access embedded resources from your application assembly.

Sure you can, use the BuildAction property as Content or Resource.
Depending on the number and structure of files/folders, you may also consider embedding one zip file and extracting it with sharpziplib or some such.
broken to bare-bones scene:
I have a program in c# that calls a .exe inside cmd(using process.start), passing some required arguments.
What i'm trying to do: Include the exe into the project so that i don't have to call cmd.
Any idea?
If you just want to include so you don't have to ship two files then just include it into the project as "embedded resource" (see project item options) and then you can call ResourceManager.GetStream and write it to file and call Process.Start.
If you want integrate the functions of that exe so that the exe is not needed anymore (no Process.Start) then you need the source code...
EDIT:
the "write to file" is not necessary if the exe is .NET - then you can directly load it from the resource stream as Assembly/AppDomin and execute it.
You can add an exe as an embedded resource (just right click on a folder in the Solution explorer, Add Existing Item, then get properties on it and set it to be Embedded Resource). However, you may not be able to easily execute it in place - you'll need to save it to disk and then execute it (which doesn't solve your stated problem of having to ShellExecute the .exe file, but does solve the problem of having to ship more than one file to the end user).
If you have the source code, then you'll be able to repackage the exe as a dll, or integrate it directly into your program code.
If the exe is a .NET assembly, you could use ILMerge to merge the exe into your main assembly. You can then invoke the code in the exe directly.
I have built a console application that works okay when it references a .exe file from a Program Files, but my users may not have that .exe in their Program Files directory.
I would prefer to keep the package as a single .exe for simplicity, so I was wondering how I can combine the two .exe's into one package.
One thing I thought of is zipping the .exe from the Program Files directory to a temporary location, and I would store the binary data for the zip archive in my console applications source code. Is this the best way to do it or are there better methods?
Note I do not have the source code of the .exe I want to reference in my console application.
You can certainly store extra files in your .exe (or .dll) as embedded resources. Simply change the "build action" for the item in the project to "Embedded Resource". You can retrieve the contents of the file (which could be compressed, if you wished) by using the following:
System.Reflection.Assembly.GetExecutingAssembly().GetManifestResourceStream("stream name")
You could extract the file onto disk to be able to reference it, or you could load it directly with one of the Assembly.Load() variants, so you wouldn't need to ever store it on disk.
Note that if you do choose to extract it and store it on disk, you'll need administrator permissions on Vista and Windows 7 (and properly administered XP) operating systems in order to save the file(s) to the Program Files directory.
You can use GZipStream to compress and decompress files in C#. For more complex compression, you can use other Zip libraries like SharpZipLib.

Basically, ILMerge will do what you are asking.
I've created a Windows Forms Application in Visual Studio 2008, .NET 3.5.
Now I want to finalize my project, i.e. to create a single .exe file which I can give to someone and he will be able to run it on his computer.
In my project files I found bin/Debug directory where I see a .exe file.
Can I just use this file as is, or I am missing some important finalizing procedure ?
Thanks !
You can just take the EXE as long as it has no dependencies. If there are any dll files in there, you need to include them (or use the ILMerge command line utility to combine them). You can, however, ignore any generated pdb or xml files.
As a side note, you should be compiling in release if you plan on deploying your project (the output will be in bin/Release)
You are not clear in you question. If your solutions output is just a single exe file, then Yes, you can give away the exe file in bin\debug.
But instead of bin\debug\ exe you must distribute the bin\Release\ exe which is meant for release purpose.
To make the ILMerge easier, use the GUI tool from codeplex at http://ilmergegui.codeplex.com/
If this is a commercial application, several commercial obfuscators allow creating a single exe.
