这是说你缺少引用一个程序
就是说你项目用到了一些控件,但是你项目本身没有引用它
可以添加using
或者在页面最上面添加System, Version=1.0.5000.0, Culture=neutral, PublicKeyToken=969db8053d3322ac
或者在你项目中BIN目录下右键添加引用
下面给你的列子
%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %
%@ Register Assembly="System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"
Namespace="System.Web.UI" TagPrefix="asp" %
看你的样子报错那行是想根据类型创建一个obj实例吧,这样的话你应该用
Dim obj = Activator.CreateInstance(t) 来创建obj实例
没有 86位?! 其实,x86 是说 兼容intelCPU芯片32位
X64 到是真的 64位
