Objectives
1. Create WCF service (host on web server )
2. Using WCF service from window form application
Hits: Step for create and using service
- Create WCF service “Student” with two operations “list()” and “detail(id)”
- Define service interface (ServiceContract)
- Define class describe detail of student (DataContract)
- Define Service by implement from server interface
- Using WCF service from window form application
- Find service description of WCF “student”
- Reference WCF service
- Call operations of student service
Student table
No. | Data field | Data type |
1. | S_ID | Int |
2. | S_FullName | Text |
3. | S_Birthdate | DateTime |
4. | S_Address | Text |

BEGIN
Open visual studio 2008 (or later)
File -> Create Project
Select as figure
Right click on project -> Add new Item
Select as figure
Right click on project -> Add new Item
Select as figure
Modified class as
1 namespace students 2 { 3 [DataContract] 4 public class StudentDetail 5 { 6 [DataMember] 7 public int ID; 8 [DataMember] 9 public string FullName; 10 [DataMember] 11 public DateTime Birthdate; 12 [DataMember] 13 public string Address; 14 } 15 } 16 17 Modified IStudent interface as 18 19 namespace students 20 { 21 [ServiceContract] 22 public interface IStudent 23 { 24 [OperationContract] 25 DataSet List(); 26 [OperationContract] 27 StudentDetail Detail(int ID); 28 } 29 }
Edit Student service as
1 namespace students 2 { 3 public class Student : IStudent 4 { 5 public DataSet List() 6 { 7 DataSet dsS = new DataSet(); 8 // insert C# code to get data from student table 9 return dsS; 10 } 11 public StudentDetail Detail(int ID) 12 { 13 StudentDetail sDetail = new StudentDetail(); 14 return sDetail; 15 } 16 } 17 } 18
Now right click on service and select view in browser
Right click on solution -> add new project
Select as figure
Design form as
GUI of client
Add service reference as
Modify form load event:
1 wcf.StudentClient proxy; 2 private void Form1_Load(object sender, EventArgs e) 3 { 4 proxy = new WCF_Client.wcf.StudentClient(); 5 }
Double click on button Find and insert code as
1 private void btnFind_Click(object sender, EventArgs e) 2 { 3 wcf.StudentDetail detail = proxy.Detail(Convert.ToInt32(txtID.Text)); 4 MessageBox.Show("Student id: " + detail.ID + "\nStudent fullname: " + detail.FullName); 5 } 6
Double click on button List and insert code as
1 private void btnList_Click(object sender, EventArgs e) 2 { 3 dgrStudent.DataSource = proxy.List(); 4 dgrStudent.DataMember = "student"; 5 }
Now run client
Client at runtime
