对Dictionary的理解

当你把字典声明的静态时,关闭网页后,你存储的数据仍然会存储在内存中,例如:

前台代码:

    <div>             <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>         <asp:Button ID="Button1" runat="server" OnClick="Button1_Click1" Text="查询" />         <asp:Button ID="Button2" runat="server" OnClick="Button2_Click1" Text="保存" />         <br />         <asp:TextBox ID="TextBox2" runat="server" Height="158px" TextMode="MultiLine" Width="225px"></asp:TextBox>         </div>

后台代码:

        static Dictionary<string, string> di = new Dictionary<string, string>();

        protected void Button2_Click1(object sender, EventArgs e)         {             di.Add(TextBox1.Text, TextBox2.Text);         }

        protected void Button1_Click1(object sender, EventArgs e)         {             if (di.ContainsKey(TextBox1.Text))             {                 string neirong = di[TextBox1.Text];                 TextBox2.Text = neirong;             }         }
