Hi, I'm a beginner of ASP.NET. When I was reading Wrox's ASP.NET 1.1 for beginner, I couldn't get the example in Chapter 13 to work. Please help me to tackle this problem, the exapmle contains a helloworld component that returns a string to the aspx page, but I couldn't get it to run, the server gives me an error cs0246:
CS0246: The type or namespace name 'WroxComponents' could not be found (are you missing a using directive or an assembly reference?)
Line 2: <%@ import Namespace="WroxComponents" %>
Source File: C:\htdocs\aspx\soccer\HellowWorldExample.aspx Line: 2
Here is my code for the component:
// HelloWorld.cs
namespace WroxComponents
{
using System;
public class HelloCS
{
public HelloCS() { }
public String SayHello()
{return "Hello World - I'm a C# component!";}
}
}
I compiled it with the command:
csc /t:library /r:System.dll /out:bin/HelloWorldCS.dll HelloWorld.cs
and my aspx page looks like this:
//aspx page,
<%@ Page Language="C#" %>
<%@ import Namespace="WroxComponents" %>
<script runat="server">
public void Page_Load()
{
HelloCS MyCSComponent = new HelloCS();
lblMessageCS.Text = aaa.MyCSComponent.SayHello();
}
</script>
<html>
<head>
</head>
<body>
<form runat="server">
<p>
Our component says:
</p>
<p>
<asp:Label id="lblMessageCS" runat="server"></asp:Label>
</p>
</form>
</body>
</html>
