Creating DLL and consuming it using C#

Description: 
DLL  Stand for  (Dynamic Link Library).
How to create a DLL and consuming it  because most of the reusable components are written in the form of a DLL.


Create DLL.

Step 1

First, create a project of type “Class Library” as shown here.

Then we are implementing a Fullname class library that is responsible for show fullname of user.

Step 3

Build this code and you will see that a DLL file has been created rather than an exe in the root directory of the application (path = C:\Users\Admin\Documents\visual studio 2017\Projects\LibraryForDLL\LibraryForTest\bin\Debug\netstandard1.4\ LibraryForTest.dll).

Consume the DLL
Step 1

 

Now create another console based application(Any project) where we will utilize the class library functionality.In my case i am created new project in same Solution Explorer.

 

Step 2

 

Then you need to add the reference of the Fullname Class Library DLL file reference to access the declared class in the library DLL. (Right-click on the Reference then select Add reference then select the path of the DLL file.)

Step 3

 

When you add the class library reference then you will see in the Solution Explorer that a new LibraryForTest is added as in the following,

Step 4

 

Now add the namespace of the class library file in the console application and create the instance of the class declared in the library as follows,

Step 5

Finally, run the application and you must see the result as shown in the image below.
