C# class - every time I add one to my code I get a "CS1513: } expected" error

I have a project that I'm working on that basically requires me to use C# code like PHP or classic ASP as opposed to using visual studio - part of that project includes adding a class - whenever I add any classes, I get "CS1513: } expected"

Guessing this is just an order / syntax thing - any advice you can provide would be greatly appreciated!

Thanks!

class MainClass4
{
    static void Main() 
    {
        PointTest p = new PointTest();
        // Direct access to public members:
        p.x = 10;
        p.y = 15;
        Response.Write("x = {0}, y = {1}", p.x, p.y); 
    }
}
// Output: x = 10, y = 15

// additional C# code here to do stuff

you can try to have a frontend and code behind structure instead.

frontend:
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="test.aspx.cs" Inherits="WebApplication_C.test" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title></title>
</head>
<body>
    <form id="form1" runat="server">
    <div>
    
    </div>
    </form>
</body>
</html>

Open in new window

code behind:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;

namespace WebApplication_C
{
    class PointTest
    {
        public int x;
        public int y;
    }

    public partial class test : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
            PointTest p = new PointTest();
            // Direct access to public members:
            p.x = 10;
            p.y = 15;
            Response.Write(String.Format("x = {0}, y = {1}", p.x, p.y)); 
        }
    }
}

Thanks Ryan,

Really appreciate it! I think I'm getting closer on this with the .cs page, but I'm confused as to how to structure the page to call the code appropriately.

Here's the actual code I'm calling in my .cs page now:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;

namespace calcdistance {

public static class GeoCodeCalc
{
    public const double EarthRadiusInMiles = 3956.0;
    public const double EarthRadiusInKilometers = 6367.0;

    public static double ToRadian(double val) { return val * (Math.PI / 180); }
    public static double DiffRadian(double val1, double val2) { return ToRadian(val2) - ToRadian(val1); }

    public static double CalcDistance(double lat1, double lng1, double lat2, double lng2) 
    {
        return CalcDistance(lat1, lng1, lat2, lng2, GeoCodeCalcMeasurement.Miles);
    }

    public static double CalcDistance(double lat1, double lng1, double lat2, double lng2, GeoCodeCalcMeasurement m) 
    {
        double radius = GeoCodeCalc.EarthRadiusInMiles;

        if (m == GeoCodeCalcMeasurement.Kilometers) { radius = GeoCodeCalc.EarthRadiusInKilometers; }
        return radius * 2 * Math.Asin( Math.Min(1, Math.Sqrt( ( Math.Pow(Math.Sin((DiffRadian(lat1, lat2)) / 2.0), 2.0) + Math.Cos(ToRadian(lat1)) * Math.Cos(ToRadian(lat2)) * Math.Pow(Math.Sin((DiffRadian(lng1, lng2)) / 2.0), 2.0) ) ) ) );
    }
}

public enum GeoCodeCalcMeasurement : int
{
    Miles = 0,
    Kilometers = 1
}

}

Open in new window


and here's what I have on the top of my main page (mainpage.aspx) that calls the .cs page (mainpage.aspx.cs)

<%@ Page Language="C#" debug="true" src="mainpage.aspx.cs" Inherits="calcdistance.GeoCodeCalcMeasurement" AutoEventWireup="true"%>

Open in new window


Right now it seems close, but I'm getting the following error:
Parser Error Message: 'calcdistance.GeoCodeCalcMeasurement' is not allowed here because it does not extend class 'System.Web.UI.Page'.

Thanks so much!!

no problem with an independent class with a different namespace, what you need is just to import and declare it accordingly in the code behind.

try this:

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="test.aspx.cs" Inherits="calcdistance.test" %>

Open in new window


then in code behind:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;

namespace calcdistance
{
    class PointTest
    {
        public int x;
        public int y;
    }

    public partial class test : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
            PointTest p1 = new PointTest();
            // Direct access to public members:
            p1.x = 10;
            p1.y = 15;

            PointTest p2 = new PointTest();
            // Direct access to public members:
            p2.x = 110;
            p2.y = 27;
            
            Response.Write(String.Format("x1 = {0}, y1 = {1}<br>", p1.x, p1.y));
            Response.Write(String.Format("x2 = {0}, y2 = {1}<br>", p2.x, p2.y));

            Response.Write(String.Format("CalcDistance = {0}", GeoCodeCalc.CalcDistance(p1.x, p1.y, p2.x, p2.y)));
        }
    }
}
