Manoj Never Gives up Re: TCP or HTTP amitcoder835-Jun-07 21:48 amitcoder83 5-Jun-07 21:48  socket or remoting whichever be the case,but why is that TCP faster than HTTP Re: TCP or HTTP originSH5-Jun-07 22:24 originSH 5-Jun-07 22:24  When sending over TCP you don't have to do much other than serialize the objects and chuck them over the connection. Using HTTP you have to use the HTTP protocol which takes more time and bandwidth. You also have the choice of the Binary Serialization and SOAP serialization. Binary makes the smallest output but SOAP is better for interop with other system or if you need the output to be human redable. In the end you need to choose which is the right combination for you based on what you need. If you need built in security and authentication then HTTP remoting via IIS is best, it also works well with firewalls. If your just working on an intranet or you really need the performance TCP will be fine.

"but" ... when explicitly implimenting an interface method it is automatically public and you cannot put any modifier on it, even the public one.

Also pls make sure you are accessing those function from a object type of Interface1 or Interface2 and not from a object of the class A directly, to get the access to those function. i.e. Interface1 interface1 = new A(); interface1.ReturnString1(); //Here you will be able to access the function. Manoj Never Gives up Re: A typical case about interfaces [modified] amitcoder835-Jun-07 21:05 amitcoder83 5-Jun-07 21:05  All the code is in C#, so if i dont specify access modifier then by default it is public after implementing the methods in an interface we can access the methods thru that class's object.why can't we do the same with this.
