Check query string in one line

Hello friends
Normally we check query string by this way

if(Request.QueryString["Item"] != null)
{
myItem = Request.QueryString["Item"].ToString() ;
Label1.Text = myItem ;
}
else
{
Label1.Text = "none";
}


We write above code in online like this.

protected void Page_Load(object sender, EventArgs e)
{
Label1.Text = Request.QueryString["Item"] != null?
Request.QueryString["Item"].ToString() : "none";
}



Even shorter way of writing the code:

Label1.Text = Request.QueryString["Item"] ?? "none";
