如何在ASP.net c#中的页面之间传递对象而不是值？

protected void Button1_Click(object sender, EventArgs e)
{
    MyClass obj = new MyClass();
    obj.Property1 = "Value1";
    obj.Property2 = "Value2";
    Session["MyObject"] = obj;
    Response.Redirect("Page2.aspx");
}

protected void Page_Load(object sender, EventArgs e)
{
    if (Session["MyObject"] != null)
    {
        MyClass obj = (MyClass)Session["MyObject"];
        Label1.Text = obj.Property1;
        Label2.Text = obj.Property2;
    }
}

protected void Button1_Click(object sender, EventArgs e)
{
    MyClass obj = new MyClass();
    obj.Property1 = "Value1";
    obj.Property2 = "Value2";
    int objId = SaveObjectToDatabase(obj);
    Response.Redirect("Page2.aspx?id=" + objId);
}

protected void Page_Load(object sender, EventArgs e)
{
    int objId = Convert.ToInt32(Request.QueryString["id"]);
    MyClass obj = GetObjectFromDatabase(objId);
    Label1.Text = obj.Property1;
    Label2.Text = obj.Property2;
}
