Today I will show how to use a .dll file using Visual Studio. dll is nothing but the a complied managed code by .NET CLR (at least for this tutorial).
what I did is just wrote a simple class “Employee” in a new project named “EmployeeInformation”. It has one property and a method jest to show that how to build a dll of a class and use it in another project.
Now i have build the class by right clicking over the project named “EmployeeInformation” and pressing build, For me a dll has been generated in “C:\Users\MD.Tanvir Anowar\Documents\Visual Studio 2008\Projects\RefTest\EmployeeInformation\bin\Debug\” directory named “EmployeeInformation.dll” you may found it in your Output panel at the bellow of VS after build the project.
Now I have to let the dll know by my main project “RefTest”, to do this i have to right click on my “RefTest” project and Click over Add Reference .
Now i have to browse and select the “EmployeeInformation.dll”
to user the dll now we have to instantiate the class in our main porject’s class by typing:
EmployeeInformation.<span style="color: #2b91af">Employee </span>employee = <span style="color: blue">new </span>EmployeeInformation.<span style="color: #2b91af">Employee</span>();
