问题
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?
回答1:
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).
回答2:
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
