Simple Question: Classes in C#

thamail

Hi all, Im having some problems getting started with C#. I can't compile the classes which I need to the ASP.NET application im trying to build, and I can't seem to understand why ... For example, when I try to compite the following code ( > csc MyStrategy.cs ): abstract MyStrategy { public abstract string decideStrategy(string name, string pw); } or public class MyStrategy { public string decideStrategy(string name, string pw){ return "..."; } } the compiler tells me that I need an entry point defined. I need a few classes to do some work for me in the ASP.NET pages that im trying to make - my plan was to make a few classes, compile them and them "embed" them in the code - just as you would do in, say a JSP page. Thanks in advance - Jim T.

well reading ur first submission.. If this is an standalone C#.net program (app or console).. every project must have an entry point. U must implement a main method from where it should start working. if its an component then u dont need any Main. And i am quite sure u are not using component creation project

Jim, I think what you need is to create a Class Library project, build it instead of start it in debug mode. You will get a .dll file after you build it. In your asp.net project, reference this dll to use the classes inside. Jan

Hi Lee, thanks for the swift reply. Well.. there arn't alot more code. I assumed, that it was possible to make a class in C# and then make it do some work in an ASP.NET page, for example when a button is clicked (instead of having the code in the void Button1_Click_1(object sender, EventArgs e) method. I've made a file called MyStrategy which is ment to be a "so called" strategy object - at the time beeing it doesn't contain alot of code but that shouldn't make it imposible to compile. e.g. the file Strategy1.cs -------------------------------- using System; public class Strategy1 { public Strategy1() { } public int method(){ return 5; } } ------------------------------- When I compile the file (>csc Strategy1.cs) I get "Program 'Strategy1.exe' does not have an entry point defined." Again, thanks in advance. -Jim T.

We would need to see a bit more code before we could help you.
