The common Ajax program is HTML + ashx, which requires a lot of communication code. However, Microsoft's WCF integrates communication code and simplifies the code.
1. Create a New WCF Server Page, and create a method and data class for the client.
Using system; using system. LINQ; using system. runtime. serialization; using system. servicemodel; using system. servicemodel. activation; using system. servicemodel. web; namespace webapplication1 {[servicecontract (namespace = "")] [aspnetcompatibilityrequirements (requirementsmode = aspnetcompatibilityrequirementsmode. allowed)] public class wcfservice1 {// <summary> // obtain user information /// </Summary> /// <Param name = "ID"> User ID </param>/ // <returns> User class for storing User Information </returns> [operationcontract] public user getuser (int id) {return new user () {username = "Xiaojiang", age = 22, address = "Wenzhou, Zhejiang "};} // Add the [webget] attribute to use http get [operationcontract] public void dowork () {// Add the operation here to implement return ;} // Add more operations here and use [operationcontract] to mark them} // <summary> // define the user class, store user data // </Summary> public class user {Public String username {Get; set;} public int age {Get; set;} Public String address {Get; set ;}}}
