I am unable to use Response.Write() in class library?

It gives me error that "The name Response does not exist in the current context".

C#

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;

namespace Default_Construtor
{
    public class Class1
    {
        public void Show()
        {
            Response.Write("Hello World");
        }
    }
}

Please suggest.

Thanks & Regards,
Aditya Kumar

You don't want to do it in a class library, if you can avoid it. However, you can do it by using the full naming:

C#

System.Web.HttpContext.Current.Response.Write(); // as i recall from memory.

It's a bad practice.
Instead you should set one flag in class file and use it later in codebehind.

Hi,

Can you please tell me how set one flag in class file and use it later in code behind?

Using bool. you can check for true/false in code behind.

Add System.Web reference and use that namespace in your class file. Add below code:

C#

namespace Default_Construtor
{
    public class Class1
    {
        public void Show()
        {
            System.Web.HttpContext.Current.Response.Write("Hello World");
        }
    }
}

And call the Show() method from code-behind file file.
