* C #-Create and use DLLs

Dynamic link library The DLL is a short form of the dynamic link library, which is a library of code and data that can be used by multiple programs at the same time, helping to share data and resources.

(i) Creating a dynamic link library

1) Create a new class library

650) this.width=650; "Src=" http://images.cnitblog.com/blog/466760/201212/ 30220335-2ba8cd2648cf4226973e6bfb684ab411.jpg "/>

2) write this class library

For example:

Using system;using system.collections.generic;using system.linq;using system.text;using System.Threading.Tasks; Namespace dlltest{public class class1{public void ShowMessage () {Console.WriteLine ("Your Are success            Ful to the call DLL. "); Console.ReadLine ();}}}

3) generate a dynamic link library

(ii) Use of dynamic link libraries

1) Add a console application--Add Reference
Right-click the project-Add reference-Browse to find the local DLL file

650) this.width=650; "width=" 182 "height=" "title=" image "style=" margin:0px;border:0px;padding-top:0px; Padding-right:0px;padding-left:0px;background-image:none; "alt=" image "src=" http://images.cnitblog.com/blog/ 466760/201212/30132816-541fa72e020e43239ef38315c6bad5e8.png "border=" 0 "/>

2) using the namespace of the code inside the DLL file

For example:

Using system;using system.collections.generic;using system.linq;using system.text;using System.Threading.Tasks;  Using Dlltest;namespace test{class program{static void Main (string[] args) {Dlltest.class1 myTest = New Dlltest.class1 (); Mytest.showmessage ();}}}

Results:
You is successful to the call DLL.
