Question

我有一个带有在服务器上运行的表的aspx页面。我写了一个代码在表中插入一行，如下面的代码所示。我想保存现在更新的aspx页面（即，如果可能，覆盖当前的），以便下次访问该页面时，所有信息都显示出来。我不想使用数据库来存储此信息，因为这只是临时的，我的托管包不支持数据库。请帮忙。

以下是我的代码：

 Dim trow As New HtmlTableRow
    Dim tcell As New HtmlTableCell

    tcell.InnerText = "Code: " & TextBox1.Text & ".   Weight: " & TextBox2.Text & ". Date: " & Now
    trow.Cells.Add(tcell)

    trow.Cells.Add(tcell)

    Table.Rows.Add(trow)
    TextBox1.Text = ""
    TextBox2.Text = ""
    'Save the aspx page
    Me.SaveControlState()
    Me.SaveViewState()

Answer 1

您可以将数据保存在Cookie中。试试这个。

Writing a cookie.

HttpCookie myCookie = new HttpCookie("MyTestCookie");
DateTime now = DateTime.Now;

// Set the cookie value.
myCookie.Value = now.ToString();
// Set the cookie expiration date.
myCookie.Expires = now.AddYears(50); // For a cookie to effectively never expire

// Add the cookie.
Response.Cookies.Add(myCookie);

Response.Write("<p> The cookie has been written.");

阅读cookie

HttpCookie myCookie = new HttpCookie("MyTestCookie");
myCookie = Request.Cookies["MyTestCookie"];

// Read the cookie information and display it.
if (myCookie != null)
    Response.Write("<p>"+ myCookie.Name + "<p>"+ myCookie.Value);
else
    Response.Write("not found");
