Beginners question

[digsy_]

I have a method in a separate class file that I'd like to call. The separate file is called dataaccessclass.cs is structured like: using System; namespace aspnetcsharpdemo { /// /// Summary description for Class1. /// public class Class1 { public static string Class11() { // this is the method that would do the select string result = "test"; return result; } } } When I try the following code it fails with - C:\Inetpub\wwwroot\aspnetcsharpdemo\test5.aspx.cs(52): The type or namespace name 'DataAccessSelectClass' could not be found (are you missing a using directive or an assembly reference?) Label1.Text = DataAccessSelectClass.Class11(); Whats the proper way to call the method ?

I can't see where your DataAccessSelectClass is coming from? And as it seems, neither can the compiler :-D For the example code you've posted, you should be using

Text1.Text = Class1.Class11();

That should give you what you need. Another thing to consider is, if you're going to just return a string that's not going to change, why not set it up as a public const string or as read only property? Steve.

well the code I posted is in a file called DataAccessSelectClass.cs (and its called from a webform1.aspx.cs page) the code inside the method is just temporary - once I figure out how to call it, the code will be changed to return a dataset.

What the file is called does not matter. This class is called Class1, or aspnetcsharpdemo.Class1. You're looking for a different class, with a method called Class11 ?? Or is Class11 a class in a namespace called DataAccessSelectClass and your code is totally confused ? Use real class names, not class1 or class11.

As Christina said, the file name is irrelevant. To access the method in the class you use: Label1.Text = aspnetcsharpdemo.Class1.Class11(); If you would have named your class DataAccessSelectClass instead of Class1, you would use: Label1.Text = aspnetcsharpdemo.DataAccessSelectClass.Class11(); And if you had using aspnetcsharpdemo; at the top of your page, or if your page class was inside namespace aspnetcsharpdemo, you could use: Label1.Text = DataAccessSelectClass.Class11();

use this Label1.Text = aspnetcsharpdemo.Class11();

sorry for the mistake use this Label1.Text = aspnetcsharpdemo.Class1.Class11(); means, namespacename.classname.function_name_of_class(); it will work
