Using a class in my code 1

[GabeC]

I know this must be a very easy answer but I just can't figure it out.

I am developing a web application using VS.Net and C#. I under stand how to use other System objects such as database communication.

using System.Data.SqlClient;

Now I have written my own class. and VS.Net created the

namespace GabeC

My class is called ComFuncs. I have a ComFuncs constructor, and a

public string isOpen(int myVariable)

function.

What I am having trouble understanding is how I use this class and function from my default.aspx.cs page.
Thanks,

Gabe

You need to instantiate a copy of your class:

ComFuncs MyComFuncs = new ComFuncs();

And then to call your method:

String Result = MyComFuncs.isOpen(42)

A way to remember things like this is to think of the class as a cookie cutter that stamps out (instantiates) objects that you can use.

chiph,

Thank you for your reply.

I do understand how to use a class in the fashion you descibe.

What I don't understand is how VS.Net and C# know where to find ComFunc. For example, I use VB 6.0 quite a bit and if I write a dll called ComFuncs, before I can use it (early bind it anyway) I need to add it as a reference to the project. In C#, before I can use ADO I need to add something like

using System.Data.SqlClient;

at the top of the class.

Here is what I am trying to do. I want to create an object that handles all my database work for me so I can use it in multiple applications. If I create a dll or class (which should I be doing?) in a project of its own, how do I use it in my other projects?

I guess I assume that since

System.Data.SqlClient;

is a system object VS.Net knows where to find it.

Does this make any sense at all? If not I will try to explain myself better.

Thanks,

Gabe

In your visual studio project window, expand the "References" section. Right-click, and select Add | Reference. Once you've done that, you can then insert the "Using blah.blah" statement at the top of your code.

Thank you. I knew it had to be something simple. I have a couple of books on C# and have read through the MSDN. I guess everyone assumes that you should know this so they don't waste space by stating it. Very similar to VB if you know what you are doing.

Thanks,
