This is one of the methods that I used in my project to call the WCF service, which is now recorded to deepen the memory. Add the Project "Simplewcf.contract" (as an example of the number of N-cubic computations), which is written in the contract for the WCF service.

In this project, add an interface that contains a method for n-th-square computation.

　　　　

1     [ServiceContract]
 2 public     interface Isquareservice
 3     {
 4         #region Get a number of n-th square value
 5         //<summary> 6//Description: Gets the n-th value of a number 7//         </summary>
 8         //<param Name= "Dbvalue" > number of calculations to be performed </param> 9//         <param name= "Intnum" > several Parties </param>
10 ///         <returns>string type calculation result
</returns>         [OperationContract]         Getsquarevalue (double dbvalue, int intnum);         #endregion     }

2. Add the Project "Simplewcf.implement", here is the implementation of the WCF service.

In this project, add a class that inherits the interfaces in "Simplewcf.contract".

　　　　

 1 [ServiceBehavior] 2 class SquareService:SimpleWCF.Contract.ISquareService 3 {4 #region gets a number of n-th square Value 5//<summary> 6///Description: Gets the n-th value of a number 7//</summary> 8//<param name = "Dbvalue" > number to be calculated by </param> 9//<param name= "Intnum" > several Parties </param>//<retur             Calculation result of ns>string type </returns> one public String getsquarevalue (double dbvalue, int intnum) 12 {13 if (Intnum < 0), the second-party calculation of the "return" will not be less than 0.
";             + + Else if (Intnum = = 0) {1 "; 20} 21             else if (Intnum = = 1): {dbvalue.tostring return (); 24} 25 Else the {double dbresultvalue = 1; +-(int i = 0; i < in Tnum; i++)-{-DBResultvalue *= Dbvalue;
Dbresultvalue.tostring return (); 38} PNS #endregion}

3. Add the Project "Simplewcf.service", which is used to unify the management of WCF services.

Right-click the project and add a WCF service named "Squareservice.svc". Delete the automatically generated interface and code implementation classes.

Right-click the service, select View markup, and modify the service item's value to "SimpleWCF.Implement.SquareService".

After the modification is complete, you can right-click the service and select "View in Browser" to view the service.

4. Add the Silverlight project "Simplewcf.client" to automatically generate a Web project "SimpleWCF.Client.Web" that hosts the project.

In "Simplewcf.client", add the service reference.

　　　　　　

Click the "Discover" button to find the WCF services available on your system. Modify the namespace to "Squareservice", which you can invoke in a Silverlight program.

The result is the following figure:
