C # Creating DLL files for program call methods

To create a dynamic DLL file method using C #:

1. In the VS2017 environment, new-project-Select the class library type;

2. Create a new. cs file (such as Test.cs) and write the following code:

1 usingSystem;2 usingSystem.Collections.Generic;3 usingSystem.Linq;4 usingSystem.Text;5 usingSystem.Threading.Tasks;6 7 namespaceTestdll8 {9      Public classTestTen     { One         Private intA; A         Private intb; -  -          PublicTest (intAintb) the         { -              This. A =A; -              This. B =b; -         } +  -          Public intAdd () +         { A             returnA +b; at         } -  -          Public intAddintXinty) -         { -             returnX +y; -         } in  -      } to}

3. Click on the project-right-rebuild, open the folder-find the Debug folder, there is TestDll.dll file

4. Calling the TestDll.dll file method in the program

A. Add TestDll.dll to the reference and invoke the instance as:

1 using Testdll; 2  3 // instantiating an object 4 New Test (35); 5   // Call method 7MessageBox.Show (Test.add (). ToString ()); 8 MessageBox.Show (Test.add (5,5). ToString ());
