Page.PreviousPage System.Threading.ThreadAbortException

A页面跳转到B页面

 

<asp:ImageButton  ID="imgSave"  ImageUrl="~/Resources/Images/btnSave.png"
                 PostBackUrl="~/Page/page001.aspx" runat="server" onclick="imgSave_Click" />

 

 protected void imgSave_Click(object sender, ImageClickEventArgs e)
        {

Response.Redirect("~/Page/page001.aspx");

      }

 

 

B页面

 protected void Page_Load(object sender, EventArgs e)
        {
              
                    if (Page.PreviousPage != null)
                    {
                        TextBox tb = (TextBox)Page.PreviousPage.FindControl("txtTitle");
                    }

}

 

结果出异常System.Threading.ThreadAbortException

 

原因是：已经写了PostBackUrl了，所以imgSave_Click不需要了，去掉就正常了
