How can I integrate C# libraries into Visual Basic? - c#

There are some libraries written in C# that I would like to use in Visual Basic, but I can't find any tutorials or anything giving me any clues as to how it is done. I have compiled (I think) the library, but I have looked everywhere (including the project properties) for a solution with no success.

If they are in the same solution, just "Add Reference" and select the C# project. If not, compile them into a .dll and "Add Reference" -> select the path to it.
You should then be able to 'Include' / 'Import' methods, classes and objects from the C# projects / libraries.

If you have compiled your C# code into a DLL, you should be able to reference it in a VB.NET project as you would any other DLL. Include your DLL somewhere in your project's folder structure (typically in a "lib" folder), then do the following:
Open your C# project in Visual Studio.
Right click on "References" in the Solution Explorer and click on "Add Reference."
Select the "Browse" tab, then browse to - and select - the desired DLL.
For more information on adding and removing references, visit this article.

You can just add it to your VB.Net project as reference and then use it. Once code is compiled (VB.Net or c#) its in IL(intermediate language) so there is no difference. Look at the example I gave in the answer of following question. I have done exactly what you are asking for.
Can C# compiler compile a VB.Net code?

Add Dynamics GP namespaces Visual Studio project

I need to add the following namespaces
• Microsoft.Dynamics.Common
• Microsoft.Dynamics.Common.Types
• Microsoft.Dynamics.GP.BusinessLogic
• Microsoft.Dynamics.Common
• Microsoft.Dynamics.GP
to my project in Visual Studio,
Kindly suggest how I can do so.
First you need to add references to the libraries to your project. Right click the project name and select "Add Reference" or if the project shows a references folder right click that and choose to add. If the library doesn't show in the list then browse to where ever it is located and select it.
Then at the top of the file add a using command. For example:
using Microsoft.Dynamics.Common;
Please feel free to post additional questions.
Either Download and install the SDK on your machine, It will include the dlls needed to integrate with dynamics or copy the dlls from where ever you have them. (make sure you get the correct version for GP). From there you should create a folder in your project to hold the files in one place and copy them there. Once you have the library files you add references to the files by going to the browse sections of the reference manager and then browsing to the where you copied the files. (Quick note. make sure that you set copy local to true so that it will include the files locally when running and not look for them in the GAC). Once referenced you should be able to access the namespaces and include them with using keyword as needed.
If in case you are not getting the required dlls even after installing SDK, then add required Nugets online in visual studio(and later). After that you can start using the keyword "using" in your VS project.

How do I install a C# class library in Visual Studio?

I am trying to use a class library which I found on a different question here.
I am quite new to C#, Visual Studio, and OOP in general, so please excuse me if this is not the right question.
I followed the link and downloaded the zip. The help file does not seem to contain any directions on how to get Visual Studio to utilize the library. I figure that I have to tell it to use the library somehow, but I really don't know what to do. Or maybe I need to copy the .dll to a specific folder. I also assume I need using ... in the top of the .cs files that use it.
How can I use this library in a Visual Studio C# project?
You should add a reference.
In the project you are working on, you can add a reference to the dll (or a library) by doing navigating to:
(Project)->References->Add Reference
[You will find Properties, References and [class]files below your project]
According to your question, you should add "UltraID3Lib.dll" to your project references and use it through adding a using on top of your project files like this:
using HundredMilesSoftware.UltraID3Lib;
After you have successfully added the resource you should build the project and it will copy all the necessary files to your output directory (bin/Release or bin/Debug).
Step 1:
Open Debug Folder (you can find it In your project Folder => Bin => Debug). Copy .dll >files there.
Step2:
In Solution Explorer Right Click on References => Add References
Go to Project Tab.
Under the Project Tab you can find Added References (References added In Debug Folder). >Simply select needed references & hit OK. You're done
Happy Coding....! :D

Using Namespaces in Other Projects

As the screenshot demonstrates, I have a project SampleApp that uses the namespaces EDAM and Thrift. I want to replicate the functionalities of SampleApp to another project.
Do I have to include the two projects (EDAM and Thrift) in my other project? Can I just copy the folders instead of including the actual project files? Can I just convert them to some sort of DLL or something?
You definitely should add references to the EDAM and Thrift projects from the SampleApp project.
To do so, follow these steps:
Right click the 'References' folder in the SampleApp project.
Select 'Add Reference...'
On the popup, go to the 'Solution' tab.
Select the EDAM and Thrift projects.
Under no circumstances should you just copy the files.
Don't copy the folders, just add references to the projects. Even if the projects are class libraries you don't want to copy the DLLs, instead you should add references, just in case your DLLs are updated:
How to: Add or Remove References in Visual Studio
If the "other" project is in the same Solution, you should be able to reference EDAM, Thrift and even SampleApp from that project much in the same way you set the references up for SampleApp.
If this "other" project will be in a new solution...I'd have to do a little research and testing.
Visual Studio project references are equivalent to referencing an assembly directly, but it has a great advantage: when you build a project, Visual Studio take cares of building its dependent projects too.
In addition, Visual Studio will prevent circular references.
There're many other pros, but it's a good summary.
Copy-pasting the code files isn't importing a namespace: this is duplicating code! And referencing the assemblies directly is a waste of time and features!

Copy C++ library to a C# project automatically on build? (Visual Studio 2010)

I have a library written in C++, and a wrapper for this library written in C#.
Both projects are under development, and the way it is now I have to manually copy the .dll from the C++ project to the C# project after each build.
So I was wondering if there was any way to make Visual Studio copy the .dll from the C++ project automatically when re-building?
You can use Build events in visual studio and place a dos command to copy the dll to the current project
Right click on the project in Solution explorer in Visual studio, select properties. There in Build events you can type:
copy c:\Cplusproject\yourproject.dll $(TargetDir)
You can use Post Build or Pre Build events based on your requirements
See this article: http://geekswithblogs.net/dchestnutt/archive/2006/05/30/80113.aspx
Use post build event for that. Just something like xcopy <yourDllFilePath> <destinationPath> and it will copy your dll file to wherever your want
if yr using that c++ dll as reference, then u might be able to add the c++ project as a project reference, and everything will be copied automaticly, and it also helps while debugging.
Click on references in yr c# project, then a dialog window opens and choose Projects and select yr c++ project
There are several approach to achieve what you request.
Here I suppose you are using Microsoft Visual C++, but on other platforms there will be analogous functionalities.
Right click on the icon representing the vc++ project on the Solution explorer
Click Properties
Select the Configuration Properties/Build Events/Post Build Event node
Write the Command Line required to copy the dll around
Remember you must do it for every Configuration and for every Platform supported from your project.
Alternatively you may ask the Linker to output directly on the location referenced by your C# project:
Right click on the icon representing the vc++ project on the Solution explorer
Click Properties
Select the Configuration Properties/Linker/General Event node
Set the Output File property to the location referenced by your C# project
That said, you may also get the dll from the c# project.

Unable to attach HTMLTidy dll (libtidy.dll) to Visual Studio

Without much luck I've been trying to attach the HTMLTidy c++ library dll within Visual Studio, however everytime I get various errors with different builds. I'm adding a reference to the project and then manually selecting the dll, which has been copied into a lib folder within the project folder.
The first dll I tried was from Mark Beaton, and I'm using his HTMLTidy wrapper as it seems the most up to date. The standard Win32 one was built.
Mark Beaton Builds
I've also tried the build from the official HTMLTidy page, again the dll
Official Build
The error when referencing, please help! I've tried compiling from source, but the source doesn't seem compatible with VS 2010.
libtidy.dll is an unmanaged C DLL, so you can't add a reference to it in Visual Studio's Add Reference dialog. You need to build the C# code from https://github.com/markbeaton/TidyManaged into a managed DLL, and add a reference to that DLL instead.
Make sure that libtidy.dll is copied to your output folder; you can achieve this by adding the DLL file to your project, and changing its properties to "Copy to Output".
