Everyone.
Please I am new to c# program. I want to ask is it is possible to combine 3 separate independent programs to one executable file.
To explain what I mean:
program_1 has its' own .sln
program_2 has its' own .sln
program_2 has its' own .sln
,and I want to has a single .sln to output a single program.exe
They are all console APP.
Any guide would be highly appreciated
You should have one solution and many projects in that solution.One of the project have program.cs that class is start point of the entire solution.Usually you will see program.cs in the Console.app or WebApi etc or WinForm. When you right click on solution instead of creating ConsoleApp create ClassLibrary Project. But even your projects have different program.cs files you can use their classess in your other projects.

I have a C# project with two namespaces. A GUI (Stoff3GUI as namespace) with the GUI xaml and .cs files, marked as starting object and a Library (Stoff3Lib as namespace) with all the classes doing the actual work.
Now, when I compile my code, I will receive a .exe file Stoff3GUI.exe and a .dll Stoff3Lib.dll. In Visual Studio, both namespaces are part of the same Project.
How can I compile the classes from the Stoff3Lib into the .exe file without producing a separated .dll file?
Edit:
Changed the xxx to my project name Stoff3 for better understanding.
If both namespaces are part of the same project, you should already only end up getting a single assembly.
This can differ with web project setups (various different flavours of web projects create assemblies in times and manners I've never understood) but for standalone executable projects, it really is "one project produces one assembly" in all cases as far as I'm aware. Double-check that you really only have one project - for example, you shouldn't have any references in the project to an xxxLib assembly.
I'm not entirely sure what you are doing here. It sounds like you might have a single 'Solution' with two projects My immediate thought is just to move the classes you want into the the GUI start project and delete the other project.
I believe what you really have is 1 Visual Studio solution with 2 projects.
Since a picture is worth 1000 words, and just to clear up terminology, here's what that looks like in VS2012:
The output of this solution is exactly what you describe:
TwoProjects\Stoff3GUI\bin\Debug\Stoff3GUI.exe
TwoProjects\Stoff3Lib\bin\Debug\Stoff3Lib.dll
The easiest way to accomplish what you want is to have a single VS project that contains 2 different namespaces. It's good practice to add folders that match your intended namespace structure, in your case Stoff3GUI and Stoff3Lib:
When you compile this solution, the output will be a single EXE, but you still maintain the separation of model and view namespaces very clearly in your folder/file structure:
OneProject\bin\Debug\OneProject.exe
Can anybody provide some code block to add an existing C# file to a project.
I have 2 projects in my solution. One project generates C# class files which will be use by second project. I have to incluse these generated files in the second project and build the project. It should be done through programatically. I know that to include these files I have to edit the C#project file (which is an XML) and make an entry that file. But I thought of
using existing code if anybody has it.
Thanks
You can ahve a look at the MsBuild.Engine namespace. It allows you to manipulate a csproj in a consistent way so you can oper the target project and add the reference programmatically.
I have a few classes that are abstracted in a way that I can use them in multiple projects. I'm always working on these classes, optimizing, adding, etc. So when I optimize something in one of these classes, I then need to copy that new version into every project I remember using it. This isn't a very good way of doing it, but is there a better way?
Thanks
Put these base classes in a single project and share this project between your different solutions as an referenced class library. This way you will not have to copy / paste anything between projects or solutions and everything should always be up to date.
You could even set-up a local NuGet feed so you can use NuGet to retrieve this shared project as a reference in a well structured and managed way.
Instead of manually copying the updated classes to every project that uses them, create a Class Library project and reference the compiled file in every project that uses the classes. Organizing your classes like that will help you to follow the DRY ("Don't repeat yourself") principle.
If you need to reference files instead of compiled libraries, however, you can reference a file as a link so that multiple projects refer to the same file without copying it to each solution folder. To do that, right-click on your project, choose Add existing item..., browse to the .cs file, and choose Add as Link from the combobox in the right lower corner.
How about if you extract the classes into a separate project, and add a reference to this project in every project you are using?
It is a bad idea to copy paste file throughout the application. To avoid these repetitions you can either:
make a link, if the amount of file is really small . In the Solution browser of Visual Studio, right click, Add Existing file, chose your file and in the split button, choose Add as a link
create a separate project and reference this project wherever is is necessary if the amount of files not tiny.
Create a base-lib and build it to a "shared" location. Add a reference to it in you project. It will keep the other projects smaller and will be faster to build.
I am developing a set of command line utilities that are very small using C#. For example, I have one application that just prints a line from a config file specified in the PATH variable.
Currently I have one project called utilities under my solution. I was wondering is there was a way to produce multiple exe files from one project. I am looking to do this because there will be about 10 different utilities and I since I already have 6 projects under my solution, I don't want to clutter it any further.
I would expect to be able to have one main function for each executable to be compiled and specify those in different namespaces.
Thanks for your help!
Maybe you just want to add a solution folder, and put all the utility projects into it?
you can share the common code in a class library so you do not have to write it multiple times. Then for each small command line application (executable) you want to create you add a windows console application to the solution.
this is the viable way in my opinion, not aware if you can configure Visual Studio to create many executables from the same sources. Could be you could get it playing around with solution and project configuration but it sounds hacky to me.
You could pass in parameters to the console executable to run each utility function:
utility.exe /command=writeline /message="This is a test"
I like using this command line parser:

It's not code-related but IDE related. I'm working on a .NET solution with about 35 different projects. These projects need to be re-organized into a new folder structure. Why? Because about 10 of those will be removed and the rest will be divided in more logical units.
One way to do this is by creating a new solution, Drag&Drop the projects into a new folder tree within the Windows explorer and then just add them to the new solution.
To be honest, that sounds dumb!
Is there a way to just move projects into different folders from within the IDE? I've tried to "save as" the projects but the IDE won't accept a different folder.
It's irritating but because there have been a few wrong choices in folder names, I'm now stuck with those names.
Example: Right now I have a project main folder which contains child folders named "Client", "Server", "Business", "Database" and whatever more. Within those child folders, there are more child folders, each a three-digit number. Within each numbered folder there's a project which is named in some logical way, like Company.Business.Customers with additional logic within this project.
The problem is that not all projects now follow this naming convention and I consider it obsolete.
A project like Company.Business.Customers should just be in a folder named Company.Business.Customers in the project root so it's easier to recognize. The name already makes it clear that it's a business class for this project. The clear division within client classes, business classes and whatever more just needs to be arranged within the solution, but I want to flatten the file structure. (And remove some obsolete projects.) Basically, I'm not refactoring, I'm just cleaning up.
VS2008 doesn't seem to have such an option, though...
Fire up notepad.exe and open the .sln file. And start Windows Explorer, navigate to the solution directory. Observe how the .sln file content matches the solution structure. Edit the entries, make the corresponding change with Explorer. Backup first.
I don't think there's an easy answer here. Your main problem is going to be that Visual Studio (or .NET) doesn't care if you have classes that belong to a different root namespace sitting in a project.
So if you have a project called Project.BusinessObjects and another project called Project.DataObjects there is nothing stopping you from putting a class called Project.BusinessObjects.User into the Project.DataObjects project.
I don't know of any way of doing all of this without a lot of manual work. Resharper will help quite a bit if you use the 'namespace rename' feature, but you're still gonna end up with a lot of grunt work.
Also, be VERY wary of doing this in conjunction with version control systems. You have to know your version control system really well to know how it's going to react to such major refactoring.
Other than that, what you are describing doing is not all that difficult. You do have to edit the solution files and maybe the project files by hand, and you might need to remove a project from a solution and add it again when it's under the right directory.
I would make a backup, and then refactor away. I think it is a mistake to think that you can do everything you need from the IDE, though. And if you do what you describe from the IDE in a source control system that uses the old Visual SourceSafe API, you will certianly (guaranteed) mess up your bindings, that API is just not made for moving (or renaming, for that matter) files around in the way you describe. The best way to do this under that scenario is to remove all source control bindings and then re-add the reorganized solution back in.
It's not that difficult, you just have to prepare (do a backup) and experiment until you get it right.
I don't think there's any way to do this from within Visual Studio, and as #gmagana points out it's going to be very difficult to do if the files are under version control.
However, it is possible to do it manually.
Start by creating the new, desired folder structure - ignore the .csproj files and solution files for now, and more the .cs files you're interested in into the new structure.
Now, fire up Visual Studio, and create a new, empty project. If you have different types of projects, you might want to create one new, empty project for each type. This will leave you with an empty .csproj file, and a .sln file with just one project.
Copy the empty project file to where they're needed, and rename them as needed. You can edit them and change the Assembly name and default namespace if you want, or wait until you're done and change the settings with Visual Studio.
Finally, edit the .sln file, and remove the Project section. Copy the empty .sln file to where you want it, and open it up in Visual Studio. Now go and add each of your existing projects to the new solution.
Within each project, click the "show all" button, and start including all the files you've copied into the project structure. Resolve missing dependencies, change the namespaces and assembly names for the project, and make sure that the code files don't specify a namespace you don't want. Repeat until done.
Once you get the new solution to build, it will be helpful to open up the DLLs in Reflector in order to ensure that you haven't missed any namespace declarations in the code file - if you're trying to get to a point where there's a 1-1 correspondence between the DLL and the namespace, or even ensuring that no namespaces are split between DLLs, Reflector is your friend.
Good luck.
I've used the following solution to solve my problem:
I started with a new, empty solution in a new folder.
For every project that needed to be moved, I used the Windows explorer to create a child folder in the solution folder, this time with the proper name.
I copied the projects from their original location to their new folders.
I added all the (moved) existing projects from their new locations.
In the Solution Manager, I renamed the projects to a better name.
I fixed the project properties and other settings for all projects.
This did clean up the whole project quite nicely. I then added the whole project to Vault (Version Control System) and once it was in the VSS, I deleted the folder again (actually, just renamed it first) and retrieved it back from the VSS system so any obsolete binaries and other garbage was gone too.
It's a lot of work, but the result turned out exactly what it needed.
