实现了用户操作时 刷新导致的重复操作问题。 实现原理如下：   使用一个上下文唯一的票据号，该票据号随页面提交或回发而递增，每当用户与服务器端交互时，代码会提取上次的票据号码并与当前票据号码比较，如果当前票据大于上次的票据，则是提交或回发，否则则识别为刷新。     这种方式会用到HttpMoudel，并在其中操作Session。   使用方法如下：   1、引入dll MsdnExt 压缩包中有2.修改web.config，在 添加以下item：               其中“MsdnModule”是一个名字， “Msdn.RefreshModule”是“Msdn”下的“RefreshModule”类型，“MsdnExt”是程序集的名字 3.引入命名空间 using Msdn; 并修改页面类继承Msdn.Page 4.使用代码  代码：  protected void Button1_Click(object sender, EventArgs e) { if (!IsPageRefresh) Response.Write("按钮事件"); else Response.Write("页面刷新");TrackRefreshState();} MSDNPage.cs 核心代码如下：using System;using System.Web.UI;using System.Web;using System.Text;namespace Msdn{ public class Page : System.Web.UI.Page { #region Constants // *********************************************************** // Constants public const string RefreshTicketCounter = "RefreshTicketCounter"; private const string SetFocusFunctionName = "__setFocus"; private const string SetFocusScriptName = "__inputFocusHandler"; // *********************************************************** #endregion // *********************************************************** // Ctor public Page() { m_focusedControl = ""; // Register a PreRender handler this.PreRender = new EventHandler(RefreshPage_PreRender); } // *********************************************************** // ************************************************************** // Indicates if the page is being viewed in response to F5 hit public bool IsPageRefresh { get { object o = HttpContext.Current.Items[RefreshAction.PageRefreshEntry]; if (o == null) return false; return (bool) o; } } // ************************************************************** // ************************************************************** // Increase the internal counter used to generate refresh tickets public void TrackRefreshState() { InitRefreshState(); int ticket = Convert.ToInt32(Session[RefreshTicketCounter]) 1; Session[RefreshTicketCounter] = ticket; } // ************************************************************** // ************************************************************** // Set the control with the input focus public void SetFocus(string ctlId) { m_focusedControl = ctlId; } // ************************************************************** #region Private Members // ************************************************************** // Create the hidden field to store the current request ticket private void SaveRefreshState() { int ticket = Convert.ToInt32(Session[RefreshTicketCounter]) 1; RegisterHiddenField(RefreshAction.CurrentRefreshTicketEntry, ticket.ToString()); } // ************************************************************** // ************************************************************** // Ensure that the ticket counter is initialized private void InitRefreshState() { if (Session[RefreshTicketCounter] == null) Session[RefreshTicketCounter] = 0; } // ************************************************************** // ************************************************************** // Handle the PreRender event private void RefreshPage_PreRender(object sender, EventArgs e) { SaveRefreshState(); AddSetFocusScript(); } // ************************************************************** // ************************************************************** // Add any script code required for the SetFocus feature private void AddSetFocusScript() { if (m_focusedControl == "") return; // Add the script to declare the function // (Only one form in ASP.NET pages) StringBuilder sb = new StringBuilder(""); sb.Append(""); sb.Append("function "); sb.Append(SetFocusFunctionName); sb.Append("(ctl) {"); sb.Append(" if (document.forms[0][ctl] != null)"); sb.Append(" {document.forms[0][ctl].focus();}"); sb.Append("}"); // Add the script to call the function sb.Append(SetFocusFunctionName); sb.Append("(); sb.Append(m_focusedControl); sb.Append();"); // Register the script (names are CASE-SENSITIVE) if (!IsStartupScriptRegistered(SetFocusScriptName)) RegisterStartupScript(SetFocusScriptName, sb.ToString()); } // ************************************************************** #endregion #region Private Properties // *********************************************************** // Private properties private string m_focusedControl; // *********************************************************** #endregion }}
