The ASPX code will look something like this:

 <asp:RadioButtonList ID="rblist1" runat="server">

    <asp:ListItem Text ="Item1" Value="1" />
    <asp:ListItem Text ="Item2" Value="2" />
    <asp:ListItem Text ="Item3" Value="3" />
    <asp:ListItem Text ="Item4" Value="4" />

    </asp:RadioButtonList>

    <asp:Button ID="btn1" runat="server" OnClick="Button1_Click" Text="select value" />

And the code behind:

protected void Button1_Click(object sender, EventArgs e)
        {
            string selectedValue = rblist1.SelectedValue;
            Response.Write(selectedValue);
        }

Technically speaking the answer is correct  but there is a potential problem remaining  string test   rb SelectedValue is an object and while this implicit cast works  It may not work correction if you were sending it to another method  and granted this may depend on the version of framework  I am unsure  it may not recognize the value     string test   rb SelectedValue     May work fine SomeMethod rb SelectedValue     where SomeMethod is expecting a string may not   Sadly the rb SelectedValue ToString     can save a few unexpected issues
