Logically its correct but you will not get info as instance will be a differnt object and not the same what is rendered to the client. Instead you can try one of the following options.

1. Pass end_address as a paramater to the constructor to harversine class.
ex: In login code behind

harversine inst = new harversine(TextBox2.Text);

2. Declare a property EndAddress in harversine class and assign the vlaue in code behind click event
ex:

harversine inst = new harversine(); inst.EndAddress =TextBox2.Text;

Can you post the actual code.

Solution 1

You could do this:

C#

public partial class Login : System.Web.UI.Page
{
    public String End_Address = string.Empty;

    protected void Page_Load(object sender, EventArgs e)
    {
    }
    public void Button1_Click(object sender, EventArgs e)
    {
        End_Address = TextBox2.Text;

Then to access it use exactly what you wrote.

You can easily do it using Properties in C#[^].
Declare a Property in harversine class.

C#

private string _End_Address;
public string End_Address
{
    get { return _End_Address; }
    set { _End_Address = value; }
}

Set it from login page. See this:

C#

public void Button1_Click(object sender, EventArgs e)
{
    harversine obj = new harversine();
    obj.End_Address = TextBox2.Text;
}

You can access it in your harversine class:

C#

public void SomeFunction()
{
    if(End_Address != null)
        string EndAdd = End_Address;
}

Refer the below link for more details:
