ASP.NET(C#)返回上一页(后退)代码
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
ViewState["BackUrl"] = Request.UrlReferrer.ToString();
}
}
/// <summary>
/// 返回按钮点击事件
/// </summary>
protected void Button1_Click(object sender, EventArgs e)
{
Response.Redirect(ViewState["BackUrl"].ToString());
}
另一种方法
在C# Web程序中，如为页面按钮写返回上一页代码
this.RegisterClientScriptBlock("E", "<script language=javascript>history.go(-2);</script>");
其中，history.go(-2)，要写为-2，因在按钮事件触发前，已刷新一次页面，所以应是-2。
Response.Write("<script language=javascript>history.go(-2);</script>");
此处也要写为“-2”。跟直接写脚本的有所不同。
