去掉.net页面中的<input type="hidden" name="__VIEWSTATE" id="_

.net 网站生成页面后，会有 <input type="hidden" name="__VIEWSTATE" id="__VIEWSTATE" value="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

这些东西怎么去掉
我把页面viewstate 设置了false,我在这个页面上放了个搜索，到其他页面，这就参数没法获取到

望高人指教

不用去掉
protected override object LoadPageStateFromPersistenceMedium()
{
return null;
}

protected override void SavePageStateToPersistenceMedium(object viewState) { }
重写这两个方法就可以

C# code


using System;
using System.Data;
using System.Configuration;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;
//添加引用
using System.IO;
using System.Threading;
namespace CCL
{
    /// <summary>
    /// BasePage 的摘要说明
    /// </summary>
    public class BasePage : System.Web.UI.Page
    {
        #region 解决ViewState过于庞大的问题
        //由于这里添加了目录,所以要建立App_Data/ViewState目录.
        protected override object LoadPageStateFromPersistenceMedium()
        {
            string viewStateID = (string)((Pair)base.LoadPageStateFromPersistenceMedium()).Second;
            string stateStr = (string)Cache[viewStateID];
            if (stateStr == null)
            {
                string fn = Path.Combine(this.Request.PhysicalApplicationPath, @"App_Data/ViewState/" + viewStateID);
                stateStr = File.ReadAllText(fn);
            }
            return new ObjectStateFormatter().Deserialize(stateStr);
        }

        protected override void SavePageStateToPersistenceMedium(object state)
        {
            string value = new ObjectStateFormatter().Serialize(state);
            string viewStateID = (DateTime.Now.Ticks + (long)this.GetHashCode()).ToString(); //产生离散的id号码
            string fn = Path.Combine(this.Request.PhysicalApplicationPath, @"App_Data/ViewState/" + viewStateID);
            //ThreadPool.QueueUserWorkItem(File.WriteAllText(fn, value));
            File.WriteAllText(fn, value);
            Cache.Insert(viewStateID, value);
            base.SavePageStateToPersistenceMedium(viewStateID);
        }
        #endregion
    }
}

一个朋友给我的

=============================================================

如果你有一个非常酷的页面，页面上很多东西自动地响应用户操作而展现丰富的变化，你的ViewState是很有可能达到200K的。

这里是我将ViewState持久化保持在服务器端的代码，这样ViewState不占用网络带宽，因此其存取只是服务器的磁盘读取时间。并且它很小，可以说是磁盘随便转一圈就能同时读取好多ViewState，因此可以说“不占时间”。为了再“不占磁盘时间”，我还使用了缓存。

一下这段代码可以放在页面中，或者页面的父类中：

C# code


protected override object LoadPageStateFromPersistenceMedium()
{
    var viewStateID = (string)((Pair)base.LoadPageStateFromPersistenceMedium()).Second;
    var stateStr = (string)Cache[viewStateID];
    if (stateStr == null)
    {
        var fn = Path.Combine(this.Request.PhysicalApplicationPath, @"App_Data/ViewState/" + viewStateID);
        stateStr = File.ReadAllText(fn);
    }
    return new ObjectStateFormatter().Deserialize(stateStr);
}

protected override void SavePageStateToPersistenceMedium(object state)
{
    var value = new ObjectStateFormatter().Serialize(state);
    var viewStateID = (DateTime.Now.Ticks + (long)this.GetHashCode()).ToString(); //产生离散的id号码
    var fn = Path.Combine(this.Request.PhysicalApplicationPath, @"App_Data/ViewState/" + viewStateID);
    ThreadPool.QueueUserWorkItem(obj => File.WriteAllText(fn, value));
    Cache.Insert(viewStateID, value);
    base.SavePageStateToPersistenceMedium(viewStateID);
}

不使用Session，因为它会“丢失”。ViewState保存在磁盘上，即使服务器重新启动，也不会丢失页面状态。

下面这段可以放在Global.asax中，也可以根本不管：

C# code


protected void Application_Start(object sender, EventArgs e)
{
    var dir = new DirectoryInfo(this.Server.MapPath("~/App_Data/ViewState/"));
    if (!dir.Exists)
        dir.Create();
    else
    {
        var nt = DateTime.Now.AddHours(-1);
        dir.GetFiles().ForEach(f =>
        {
            if (f.CreationTime < nt)
                f.Delete();
        });
    }
}

这可以确保绝对稳定可靠地工作。以后请放心使用ViewState，把交互式页面提高水平才是最重要的，不要纠缠在“ViewState太大”上。实际上，由于页面设计不够酷，交互变化看上去不够丰富，ViewState实在是太小太小了。

如果你使用了它有效提高了复杂交互页面的效率，可以说一下提高了多少？！如果你觉得没用，也可以说一下在什么情况下没用。
