Building a Class Library, and 2. Building a client application to test the DLL. Part 1 Creating a Class Library DLLCreate an Empty Class Library Project. Select File New Project Visual C Projects Class Library. Select your project name and appropriate directory using Browse button and click OK. See Figure 1. Figure 1. Project and Its files. The Solution Explorer adds two C classes to your project. First is Assembly. Info. cs and second is Class. We dont care about Assembly. Info. We will be concentrating on Class. See Figure 2. Figure 2. The mc. Math Namespace. When you double click on Class. Math. We will be referencing this namespace in our clients to access this class library. System namespace mc. Math lt summary Summary description for Class. Class. 1 public Class. TODO Add constructor logic here Now build this project to make sure every thing is going OK. After building this project, you will see mc. Math. dll in your projects bindebug directory. Adding Methods Open Class. View from your View menu. Right now it displays only Class. Lets add one method and one property. See Figure 3. Figure 3. Right click on Class. Add Add Method.   See Figure 4. Figure 4. C Method Wizard pops up. Add your method name, access type, return type, parameters, and even comments. Use Add and Remove buttons to add and remove parameters from the parameter list respectively. I add one test method called mc. Test. Method with no parameters. See Figure 5. Figure 5. I am adding one more method long Add long val. This method adds two numbers and returns the sum. Click Finish button when youre done. See Figure 6. Figure 6. The above action adds two method to the class and methods look like following listing lt summary This is a test methodlt summary publicvoid mc. Test. Method   public long Addlong val. Adding Properties. Open C Property Wizard in same manner as you did in the case of method and add a property to your class. See Figure 7. Figure 7. This action launches C Property Wizard. Here you can type your property name, type and access. You also have options to choose from get only, set only or get and set both. You can even select if a property is static or virtual. I add a property Extra with public access and bool type and getset option set. See Figure 8. Figure 8. Msr206 Card Reader Software here. After adding a method and a property, our class looks like Figure 9 in Class View after expanding the class node. Figure 9. If you look your Class. Wizards have added two functions to your class. This is a test propertylt summary publicbool Extra getreturntrue setAdding Code to the Class Add this code bold to the methods and property now. And now I want to change my Class. Math. Comp because Class. Make sure you change class name and its constructor both. Note Im not adding any code to mc. Test. Method, You can add any thing if you want. System namespace mc. Math lt summary Summary description for Class. Math. Comp privatebool b. Test false public mc. Math. Comp TODO Add constructor logic here lt summary This is a test method lt summary publicvoid mc. Test. Method publiclong Addlong val. This is a test property lt summary publicbool Extra get return b. Test set b. Test Extra Build the DLLNow build the DLL and see bindebug directory of your project. You will see your DLL. Piece of cake Huh Part 2 Building a Client Application. Calling methods and properties of a DLL from a C client is also an easy task. Just follow these few simple steps and see how easy is to create and use a DLL in C. Create a Console Application Select File New Project Visual C Projects Console Application. I will test my DLL from this console application. See Figure 1. 0. Figure 1. Add Reference of the Namespace. Now next step is to add reference to the library. You can use Add Reference menu option to add a reference. Go to Project Add reference. See Figure 1. 1. Figure 1. Now on this page, click Browse button to browse your library. See Figure 1. 2. Figure 1. Browse for your DLL, which we created in part 1 of this tutorial and click Ok. See Figure 1. 3. Figure 1. Add Reference Wizard will add reference of your library to the current project. See Figure 1. 4. Figure 1. After adding reference to mc. Math library, you can see it as an available namespace references. See Figure 1. 5. Figure 1. Call mc. Math Namespace, Create Object of mc. Math. Comp and call its methods and properties. You are only one step away to call methods and properties of your component. You follow these steps 1. Use namespace Addusing mc. Math in the beginning for your project. Math 2. Create an Object of mc. Math. Compmc. Math. Comp cls new mc. Math. Comp 3. Call Methods and Properties. Now you can call the mc. Math. Comp class method and properties as you can see I call Add method and return result in l. Res and print out result on the console. Math. Comp cls new mc. Math. Comp long l. Res cls. Add 2. Extra false Console. Write. Linel. Res. To. String Now you can print out the result. The entire project is listed in the following Listing using System using mc. Math namespace mc. Client lt summary Summary description for Class. Class. 1 lt summary The main entry point for the application. STAThreadstaticvoid Mainstring args mc. Math. Comp cls new mc. Math. Comp long l. Res cls. Add 2. Extra false Console. Write. Linel. Res. To. String Now build and run the project. The output looks like Figure 1.
