我遇到了交叉分页和我的get语句的问题

Question

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

public partial class pgCheckOut : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
   {

    }


    public TextBox FirstName()
    {

        get
        {

            return txtFirstName;

        }

    }




}

我一直收到以下错误...错误2只能将赋值，调用，递增，递减和新对象表达式用作语句
