Unable to call App_Code class from a code-behind
I have a class in a file that's in the "App_Code" folder. I'm able to use this in an "aspx" file but not from a code-behind file. How do I make it visible to a code-behind?
NOTE: This is ASP.Net on Mono and I'm writing the classes directly, not using an IDE to compile them
My files:
ASPX FILE (testappcode.aspx)
<%@ Page language="c#" src="TestAppCode.aspx.cs" Inherits="TestAppCode.TestAppCode" AutoEventWireup="true" %>
<html>
<head>
<title>Test App_Code Folder</title>
</head>
<body>
<form id="contactForm" runat="server">
<asp:TextBox id="Name" runat="server" ></asp:TextBox>
<asp:TextBox id="Age" runat="server" ></asp:TextBox>
<asp:Button ID="Submit" runat="server" Text="Submit" onclick="SubmitForm" />
</form>
</body>
<html>
CODE BEHIND (TestAppCode.aspx.cs)
using System;
using System.Web.UI.WebControls;
namespace TestAppCode
{
public class TestAppCode : System.Web.UI.Page
{
protected void SubmitForm(object sender, EventArgs e)
{
//It fails here with the error: CS0246: The type or namespace name
//`MyAppCodeClass' could not be found. Are you missing a using
//directive or an assembly reference?
MyAppCodeClass m = new MyAppCodeClass();
}
}
}
APP_CODE CLASS (App_Code/MyAppCodeClass.cs)
public class MyAppCodeClass
{
public MyAppCodeClass() {}
}
I tried giving it a namespace, but that doesn't fix the issue.
Answer
Change your class' Build Action to Compile.
