ASP.Net回送。数据提交另外页面

SetPage.aspx

GetPage.aspx

1、SetPage.aspx

主要：button属性设置为PostBackUrl="~/Upload/GetPage.aspx"

<table cellpadding="0" cellspacing="0" class="auto-style1">
                <tr>
                    <td class="auto-style2">Event</td>
                    <td>
                        <asp:DropDownList ID="ddl_events" runat="server">
                            <asp:ListItem>a</asp:ListItem>
                            <asp:ListItem Selected="True">b</asp:ListItem>
                            <asp:ListItem>c</asp:ListItem>
                        </asp:DropDownList>
                    </td>
                </tr>
                <tr>
                    <td class="auto-style2">First Name</td>
                    <td>
                        <asp:TextBox ID="firstName" runat="server"></asp:TextBox>
                    </td>
                </tr>
                <tr>
                    <td class="auto-style2">Last Name</td>
                    <td>
                        <asp:TextBox ID="lastName" runat="server"></asp:TextBox>
                    </td>
                </tr>
                <tr>
                    <td class="auto-style2">Email</td>
                    <td>
                        <asp:TextBox ID="email" runat="server"></asp:TextBox>
                    </td>
                </tr>
                <tr>
                    <td class="auto-style2">&nbsp;</td>
                    <td>
                        <asp:Button ID="Button1" runat="server" Text="Button" PostBackUrl="~/Upload/GetPage.aspx" />
                    </td>
                </tr>
            </table>

GetPage.aspx
弱接收数据

if (!IsPostBack)
            {
                try
                {
                    //1.
                    DropDownList ddl_events = (DropDownList)PreviousPage.FindControl("ddl_events");

                    string events = ddl_events.SelectedValue;
                    string firstName = ((TextBox)PreviousPage.FindControl("firstName")).Text;
                    string lastName = ((TextBox)PreviousPage.FindControl("lastName")).Text;
                    string email = ((TextBox)PreviousPage.FindControl("email")).Text;

                    this.lbl_message.Text = "events:" + events + "<br/>"
                        + "firstName:" + firstName + "<br/>"
                        + "lastName:" + lastName + "<br/>"
                        + "email:" + email + "<br/>";
                }
                catch{
                    lbl_message.Text = "Request Fail";
                }
            }

2、强接收数据：

2.1 建立类

public class RegistrationInfo
    {
        public string events { get; set; }
        public string firstName { get; set; }
        public string lastName { get; set; }
        public string email { get; set; }
    }

2.2 SetPage.aspx添加公共属性RegistrationInfo

public RegistrationInfo RegistrationInfo
        {
            get {
                return new RegistrationInfo
                {
                    events = this.ddl_events.SelectedValue,
                    firstName = this.firstName.Text,
                    lastName = lastName.Text,
                    email = email.Text
                };
            }
        }

2.3 GetPage.aspx调用

try
                {
                    //2.
                    RegistrationInfo ri = PreviousPage.RegistrationInfo;

                    this.lbl_message.Text = "events2:" + ri.events + "<br/>"
                        + "firstName:" + ri.firstName + "<br/>"
                        + "lastName:" + ri.lastName + "<br/>"
                        + "email:" + ri.email + "<br/>";
                }
                catch{
                    lbl_message.Text = "Request Fail";
                }
