Hello Sir,
I have three classes in my website project named class1.cs, class2.cs and class3.cs.
These three classes are declared in the same namespace and now I want to create a DLL for these classes.
That is one DLL only.
How can I create that?
Can anybody please tell me?

Thank you!

Solution 1

You'll have to create an additional project in your solution. The output type must be selected as "Class library". In order to use that in your ASP.NET project you'll need to reference your class library from the ASP.NET project.

Still have a question? Feel free to leave me a comment.

Cheers!

You must first create a solution. This solution which is in fact a collection of projects will contain your ASP.NET project and the class library project.

A good comprehensive answer though I would say a short quote from your answer would be nice :P My 4 :) Ed

Why do you think it's better?

It's personal preference to be honest. If you give a short quote then the reader can see what they are being linked to and whether it is actually what they want rather than having to load a whole new page. This is especially useful if your on a slow computer or slow/costly internet connection :P Not that I'm on either any more but used to be...:P

Sergey Alexandrovich Kryukov 1-Mar-11 15:52pm

Sure, some personal preference. But... Reuse!

Yes always reuse otherwise, what's the point of having a forum ;P

Solution 2

To create an assembly you will need to create a project class library project. In this project you will create your reportclass.cs class file. When you build this it will produce the DLL file. Unfortuantely you cannot create web pages in this type of project.
