WCF Data Services - WebInvoke Method

Question

User-1080777599 posted

I am using a WCF Data Service to insert data into the Databse via Entity Framework 5.0.

I need to insert an Object of type Employee to the Employee Table using a WebInvoke method.

But WebInvoke method is not allowing custom objects as input parameters. It says 'Only primitive data types are allowed'.

How do I pass this parameter to the service side or should I use some other method for this?

 For eg:-

 [WebInvoke(Method = "POST")]        

public int AddEmployee(Employee Obj)  

       {                       

  return 1;      

   }

you could use serialization. Meaning:

• Convert the object "Obj" to an xml string (using the XmlSerializer)
• Change "AddEmployee(Employee Obj)" to "AddEmployee(String employeeStr)"
• Deserialize in the implementation

Or instead of Xml serialization, you can apply json serialization, ...

You can define youe employee class with DataContract -

 [DataContract()]
class Employee
{
    // properties as data member here
}
