Question

How can I send complete IList from application to WCF? Then on the basis of that IList, I want to Save data in Database. For Example:

I have below function in my app.

private IList<Users> UserList() {

}

Now in my WCF i have Below Function

public Void SaveUser(Users U) {

}

Now I want to send whole list of UserList Function from My Application to WCF, and call SaveUser @ WCF.

I can do the whole operation with Loop also by calling SaveUser of WCF withing Loop of my USerList in Application. But due to Performance reasons, I want to avoid this method.

Answer 1

I assume your WCF service currently defines that method as an OperationContract?

[OperationContract]
public Void SaveUser(Users U);

You can just add another method that takes a List, or an Array:

// added to the service interface
[OperationContract]
public Void SaveUsers(List<Users> users);

// added to the implementation of the service
public Void SaveUsers(List<Users> users) {
  foreach(var user in users)
  {
    SaveUser(user);
  }
}

This is of course assuming you have control over the WCF service and can add that to its contract.
